Siempre Verde Reserve is located in Imbabura Province, Ecuador, in the northwestern Andes within the “Chocó-Andean Corridor” and occupies an area of 504 ha, ranging in elevation from about 2300 to 3500 m. It is privately owned by the Lovett School, originally purchased in 1992 to construct a research center and to protect one of the few remaining tracts of undisturbed cloud forest in the region. It was legally established as a “bosque protector” by the Ecuadorian government in 1994. A study was initiated in April, 2016, to inventory the flora and assess the conservation value of the site by collecting botanical specimens and by evaluating prior and on-going studies on the flora and fauna of the site. The resulting study documents 408 taxa of vascular plants, including 42 pteridophytes, 1 gymnosperm, and 365 angiosperms. Of the angiosperms, 47 are Monocots, 24 are Magnoliids and Chloranthales, and 294 are Eudicots. Included in the list are 40 taxa endemic to Ecuador and 97 taxa on the IUCN Red List of Threatened Species. Previous and on-going studies indicate a high diversity of orchids, epiphytes, and a rich fauna, including many plant-animal associations involving bats, birds, and insects. Some of Ecuador’s most charismatic and threatened animals are known from Siempre Verde, including the spectacled bear, the puma, the olinguito, and at least nine species of bats. Much of the lower elevations along the river and around the building sites have been highly disturbed, but the higher elevations are still occupied by mature forest, with “elfin” forest at the higher sites. In comparisons with the tree and shrub species of other selected cloud forest studies in the region it was found that Siempre Verde shares 41 to 68% of the genera and 14 to 28% of the species for the lower montane zone, and 73 to 87% of the genera and 22 to 42% of the species for the upper montane zone. Notably, there are 30 genera and 144 species at Siempre Verde not found at any other of the 14 sites selected. Several non-native plant species were found, but none were particularly invasive. These results suggest that a rich flora exists at Siempre Verde, and that the Reserve harbors a unique combination of species unlike other similar cloud forest sites, providing evidence of the high conservation value of the site. Already a part of Ecuador’s private forest reserve system, Siempre Verde Reserve is located in a region facing increasing threats from mining activities and climate change, and like other cloud forest sites in the region, faces a precarious future. This study summarizes the biological richness at the site, highlights the uniqueness of the Siempre Verde Reserve, and provides an important tool for decision-making and conservation policy.

Microlicia crenatifolia is described from the Diamantina Plateau, a well-known hotspot of plant endemism in southeastern Brazil. It can be recognized by its small leaves (up to 8.3 mm long) that are conspicuously crenulate to slightly serrate, short floral pedicels (0.7–1.0 mm long), and linear calyx lobes that are externally glandular-punctate and covered with short gland-tipped trichomes 0.1–0.3 mm long. We provide line drawings, SEM photos of leaves, seeds and indumentum, a distribution map, and an identification key to M. crenatifolia and putative relatives (M. canastrensis, M. pabstii, M. serratifolia, and M. thomazii).

The objectives of this investigation are to study nitrogen uptake, translocation, accumulation and distribution in mango tree organs using labeled nitrogen (15N) and to understand the mechanism of boron action in increasing fruit yield in the off-year. A field experiment was conducted using fifteen-year-old mango trees (cv. Zebda) grown at Al Malak Valley Farm, El-Sharkeya Governorate-Egypt. Treatments included the application of (15NH4)2SO4, “in the on-year”, at a rate of 50 g nitrogen/tree through the stem injection technique. While boron was sprayed on the same trees “in the off-year” at the following rates: 0.0 (control), 250 and 500 mg·L–1. The authors hypothesize that boron and nitrogen act synergistically to increase mango fruit yield in the off-year. Results indicated that the highest 15N uptake and accumulation in the on and off-years was observed in the upper (young leaves). When boron was applied at 250 mg·L–1, in the off-year, the upper (young leaves) recorded the highest 15N uptake and accumulation (%15Ndff = 13.93) relative to the other two leaf categories and those of the on-year. In the on-year fruit accumulated higher 15N than leaf or bud. In the off-year, bud exhibited the highest 15N accumulation without boron application, while leaves exhibited the highest 15N with boron application. The highest %15Ndff in all tree organs was observed at 250 mg·L–1 boron rate. Boron increased nitrogen uptake, translocation and accumulation in mango tree organs. A synergistic relationship was observed between boron and nitrogen which led to an increase in fruit yield in the off-year.

Amenity trees are an essential element of most urban communities, contributing significantly to human well-being and improving environmental quality. Good knowledge of the diversity and abundance of trees in our environment and their importance can help promote conservation, which is essential for sustainability. This study aimed at assessing the diversity and abundance of amenity trees on the premises of the International Institute of Tropical Agriculture (IITA), Ibadan Nigeria. The institute was divided into working and residential areas. The trees in the study area were identified using a walking and windshield survey. A total population of 2626 trees from 126 species and 42 families were identified on the premises of IITA. The highest tree population of 523 trees was recorded in the Tropical Crescent residential area with 321 trees of Lagerstroemia speciosa being the most frequent species. Across working and residential areas, Elaeis guineensis was the most frequent species accounting for 19.92% of the total tree population. A Shannon-Wiener Diversity Index (H’) of 3.383 and species evenness of 0.43 was obtained from the study area. The high values of diversity indices obtained indicate that IITA premises are rich in diverse tree species both indigenous and exotic hence should be referenced as a good urban landscape. The current management practices can be recommended for other institutions.

From the publisher: This magnificent flora of the Sonoran Desert’s southern edge represents decades of meticulous workand the genius of Richard Felger (1934–2020) and his colleagues at their best. It is many things at once. A project of passionthat was sparked by a trip in 1953 by an impressionable young scientist whose world was opened by canyons lined withpalms, fig trees, agaves, and plants awaiting his description. The most thorough treatment of the plants of the southern halfof the Sonoran Desert ever assembled, which fills a long-standing gap in the knowledge of Mexican Biodiversity. A florabrought to life by hundreds of vivid and beautiful images of the majority of the 837 plant taxa found here, most by SueCarnahan, who brought this life-spanning project to realization with Richard and Jesus. And a flora made approachablethrough accurate diagnostic keys (as Richard says, “the poetry of botany”), tailored to this specific region over years in thecanyons and along the coasts and countless hours at the herbarium refining measurements and decoding a floristic jumbleinto an orchestrated whole.

The Convolvulaceae is a diverse family and it is particularly well represented in Mexico. The current inventory confirms the presence of 313 species within Mexico, and this quantity represents nearly 20% of the family’s global diversity. Convolvulaceae species are found in all states of our country but are most frequent at elevations below 1500 m. The preferred habitat is tropical deciduous forest and secondary communities derived from it. Whereas most species are herbaceous to woody climbers, it is noteworthy that some species are arborescent, and the distribution of this growth form is essentially Mexican, with a few species in the Andes.

Castner Range National Monument encompasses 2.70 ×107 m2 of land in the northeast section of the Franklin Mountains adjacent to El Paso, Texas to the east and surrounded by Franklin Mountains State Park. The vegetation of this area has remained mostly undisturbed, outside of its role as a military weapons firing range from 1926 to 1966. A checklist of the plant species present in the area has not previously been published. In order to provide a comprehensive vascular plant list of the Castner Range National Monument, we compiled records of historical plant specimens of the UTEP Herbarium and other digitized records from SEINet and GBIF databases for georeferencing. Using QGIS, a map of vascular plant specimens found within the boundary of the Castner Range was constructed, which included 1,637 records. This data was supplemented with verified observational data from iNaturalist. From these records, we constructed a vascular plant checklist. A total of 82 families, 293 genera, and 470 species (and subspecies or varieties) of vascular plants were identified to occur in the boundaries of Castner Range National Monument. Two species, Escobaria sneedii and Sicyos glaber, have global vulnerable status (G3), and several collections in the Castner Range and Franklin Mountains represent the only records in Texas. This checklist can be applied to future studies and the high level of diversity helps justify preservation efforts regarding this area.
