Reinwardtia 21(2): 63‒80. — There are 53 species and three varieties of Sumatran Cyrtandra (Gesneriaceae) included in the checklist. Thirty-three lectotypes and four neotypes have been assigned, including for two excluded species. Two species are designated as incertae sedis due to a lack of type material or any associated specimens. A new name of C. jackii is proposed here to replace the illegitimate C. glabra Jack. Most of the species included in the checklist are endemic to Sumatra, with some species distributed in neighboring islands in Malesia. The next step for Cyrtandra in Sumatra is to carry out a full taxonomic revision to better understand distribution patterns and species limits and also to assign appropriate neotypes for those species still missing original material.

MANSUR, M., SALAMAH, A., MIRMANTO, E. & BREARLEY, F. Q. 2022. Nutrient concentrations in three Nepenthes species (Nepenthaceae) from North Sumatra. Reinwardtia 21(2): 55‒62. — Nepenthes is a genus of carnivorous plants that are unique ornamental plants, but their nutrient concentration relationships have not been studied much, especially in endemic species on the island of Sumatra. So far, the analysis of the nutrient concentration in Nepenthes is mostly limited to leaves. There are few reports of nutrient concentrations in the pitcher fluid and the soil around where it grows. Leaves, pitcher fluid, and soil around the growth sites of each species i.e., Nepenthes sumatrana, N. spectabilis, and N. tobaica, from North Sumatra province were collected for nutrient analyses (N, P, K, Ca, Mg, and Na). The results showed that the nutrient concentrations in the leaves and pitcher fluid in the three Nepenthes species were generally low with those in the leaves greater than in the pitcher fluid. The concentration of nutrients in the leaves of N. sumatrana (lowland species) was least (except for N and Na) when compared to N. spectabilis and N. tobaica (highland species), likely reflecting the poorly fertile soil. In contrast, the nutrient concentration in the pitcher fluid of N. sumatrana was greater than N. spectabilis and N. tobaica. When compared across an extensive data set, we show that leaf N does not change with elevation, whereas P declines and the N:P ratio increases with elevation, suggesting that Nepenthes plants are obtaining sufficient N from prey at higher elevations.

YULIZAH, RAHAJOE, J. S., FEFIRENTA, A. D. & NUGROHO, A. D. 2022. The population and distribution of agarwood producing tree (Aquilaria malaccensis) in Riau Province. Reinwardtia 21(1): 1–11. — Riau Province is one of the largest agarwood producers and supplier of Aquilaria malaccensis species in Indonesia, based on the data of trade quota that was issued by the Ministry of Environment and Forestry in 2018. The quota data will be used for monitoring the sustainability of the population agarwood producing trees in the wild. The aimed of the study were to determine the natural population distribution and habitat preference of wild agarwood-producing trees in Riau Province. The agarwood population census carried out by making random plots in the study sites, soil moisture, soil pH, temperature and the humidity recorded, and the macronutrients data also used to support the habitat preferences for the agarwood producing taxa tree. Seven locations of agarwood producing trees were selected for the study sites including Taman Hutan Raya (TAHURA: Forest Park Garden) Sultan Syarif Hasyim (SSH), three community forests in Siak Sri Indapura District (Gosib, Perincit and Dosan), and three community forests in Bengkalis District (Langkat, Pangkalan Jambi, and Duri Km 13). The density of agarwood producing trees in TAHURA SSH recorded for about 38 plants ha-1, with an average diameter distribution was 15 cm, and the tree height was 9.51 m. Perincit data showed the highest density, with 8.13 plants ha-1 with an average distribution of tree diameters was recorded for 20.8 cm and the tree height was 9.11 m. While the lowest tree density was recorded for 0.58 plant ha-1 in Gosib, the average diameter and tree height were recorded for 40.15 cm and 14.70 m, respectively. Environmental parameters and soil chemistry were the main factors to support the tree growth of agarwood. The result was necessary for the conservation program of A. Malaccensis, and support data for providing potential seeds source and seedling. The nutrient content preference from the finding of this research will also be used as the necessary information of the needs of nutrient content in the natural habitat of agarwood plantations.

SEDAYU, A., SARASWATI, R. A. & ASTUTI, Y. P. 2022. Light preferences in two landscape managements and ontogenic light requirements of terrestrial ferns in Kebun Raya Baturraden, Central Java. Reinwardtia 21(1): 25–33. — Human management on landscapes influences environmental requirements including solar irradiation, which may affect fern establishment in different age classes. Two contrasting terrestrial fern communities were inspected in Kebun Raya Baturraden, Central Java; the first thrives among the garden (collection) area, representing the well managed area, and the latter living on the less managed area closest to a natural forest remnant. We found 78.7% species living exclusively in either landscape type; only 21% were shared on both, indicating a light preference among ferns and lycophytes. The four most common species (out of 32 fern and lycophyte species), Cyclosorus heterocarpus, Selaginella ornata, Nephrolepis biserrata, and Sphaerostephanos arbuscula in three different age classes and under gradient canopy openness were surveyed. Statistical test on the canopy openness of individuals of S. ornata and N. biserrata showed that three age categories used significantly different canopy openness, which is not the case for C. heterocarpus and S. arbuscula. It showed that some ferns and lycophytes ontogenically have gradual requirements on light exposure, while others are able to live in wide range of light exposure. This implies that in terms of wild species management, including ferns, the Baturraden gardens landscape management must be directed toward the ecological understanding of species of interest for Botanical Gardens and conservation
SEDAYU，A.，SARASWATI，R.A.和ASTUTI，Y.P.2022。中爪哇Kebun Raya Baturraden陆地蕨类植物的两种景观管理中的光偏好和个体发生光需求。Reinwardtia 21（1）：25-33--人类对景观的管理会影响环境需求，包括太阳辐射，这可能会影响不同年龄段的蕨类植物的建立。在中爪哇的Kebun Raya Baturraden考察了两个截然不同的陆地蕨类群落；第一种生长在花园（收藏）区，代表管理良好的地区，而后者生活在最接近天然林遗迹的管理较少的地区。我们发现78.7%的物种只生活在两种景观类型中；两者仅占21%，这表明蕨类植物和番茄属植物对光的偏好。调查了三个不同年龄段和梯度冠层开放度下最常见的四种蕨类植物（32种蕨类植物和番茄植物中），即异果环孢属、卷柏属、双叶肾孢属和熊果木属。对S.ornata和N.biserrata个体冠层开放度的统计测试表明，三个年龄组的冠层开放度显著不同，而C.heterarpus和S.arbscula则不然。研究表明，一些蕨类植物和番茄属植物在个体发育过程中对光照有逐渐的要求，而另一些则能够在宽范围的光照中生活。这意味着，就包括蕨类植物在内的野生物种管理而言，巴都拉登花园的景观管理必须着眼于对植物园和保护所关注物种的生态理解

A. & ASTUTI, Y. P. 2022. Light preferences in two landscape managements and ontogenic light requirements of terrestrial ferns in Kebun Raya Baturraden, Central Java. Reinwardtia 21(1): 25–33. — Human management on landscapes influences environmental requirements including solar irradiation, which may affect fern establishment in different age classes. Two contrasting terrestrial fern communities were inspected in Kebun Raya Baturraden, Central Java; the first thrives among the garden (collection) area, representing the well managed area, and the latter living on the less managed area closest to a natural forest remnant. We found 78.7% species living exclusively in either landscape type; only 21% were shared on both, indicating a light preference among ferns and lycophytes. The four most common species (out of 32 fern and lycophyte species), Cyclosorus heterocarpus, Selaginella ornata, Nephrolepis biserrata, and Sphaerostephanos arbuscula in three different age classes and under gradient canopy openness were surveyed. Statistical test on the canopy openness of individuals of S. ornata and N. biserrata showed that three age categories used significantly different canopy openness, which is not the case for C. heterocarpus and S. arbuscula. It showed that some ferns and lycophytes ontogenically have gradual requirements on light exposure, while others are able to live in wide range of light exposure.
