June 2019. The New England Botanical Club held its June away meeting at the Vermont Grange Center, in Brookfield, Vermont, and included a weekend full of activities from June 14 to 16. Friday arrivals enjoyed a potluck dinner together. On Saturday morning, Ernie Schori cooked up breakfast and everyone headed out to a field trip or workshop. Charley Eiseman gave a most interesting workshop on galls, leaf mines, and other signs of herbivorous insects, introducing participants to arthropods that feed on plants. Participants learned to identify a number of insects and arachnids, many of which can be identified to species by the plant host and type of damage. Art Gilman led a field trip to Berlin Pond where the group studied willows, including Salix bebbiana, S. discolor, S. eriocephala, S. nigra, S. petiolaris, S. sericea, and one probable hybrid with the persistent stipules of S. eriocephala and the abundant, silky hairs on the abaxial leaf surfaces of S. sericea. They also visited a fern hotspot with Goldie’s fern (Dryopteris goldieana), bulblet-bladder fern (Cystopteris bulbifera), maidenhair fern (Adiantum pedatum), and a hybrid of male fern (Dryopteris filix-mas) and marginal fern (D. marginalis); long known as Vermont fern and now called Jim Montgomery’s fern (D. 3 montgomeryi). They ended the day at Williamstown Gulf, a deep north-south chasm created by glacial meltwater where they explored a very rich northern hardwood community. The group found Wherry’s hybrid woodfern (Dryopteris3 neowherryi [D. goldiana3marginalis]) and a large population of glade fern (Homalosorus pycnocarpon), along with numerous rich woods species. Brett Engstrom took a group to Chickering Bog Natural Area (an intermediate fen) and then to Calais Town Forest. On the trail hike to the fen, Brett and others pointed out features of the northern forest (moose tracks, abundant white spruce, a millipede that smells like almonds) and interesting species: Carex peckii (historical in Massachusetts), Lobaria pulmonaria (lung lichen), and deer truffles Elaphomyces granulatus. The fen was stunning, with flowering Sarracenia purpurea (purple pitcherplant), Utricularia (bladderworts) and Tricophorum alpinum (alpine sedge). Sedges observed included the beautiful Carex limosa, C. peckii, C. palescens, C. aquatilis, and C. lasiocarpa, among others. The highlight of the trip was seeing Pyrola asarifolium (pink pyrola).

ABSTRACT. Silene regia Sims (Caryophyllaceae), commonly referred to as royal catchfly, is known to ensnare small insects with its glandular trichomes. This morphological adaptation is primarily thought to deter herbivory, but in many plant species glandular trichomes have been co-opted to secrete digestive enzymes that, when combined with an ability to absorb released nutrients, form the basis of a carnivorous life habit. To determine if S. regia is carnivorous we investigated the following: (1) whether S. regia actively attracts, captures, and retains prey, and/or secretes digestive enzymes to facilitate nutrient absorption; and (2) whether it absorbs and translocates the resultant nutrients. We tested the first requirement of carnivory through field observations, ultraviolet photography, scanning electron microscopy imaging, and a series of experiments designed to examine a capture-induced proteinase response. While S. regia was able to passively ensnare insects and possessed highly specialized morphological structures for doing so, a form of active attractant could not be demonstrated. Furthermore, negative test results for a capture-induced proteinase response suggest S. regia does not actively secrete proteases that would act on captured insects. As the criterion of actively attracting and/or digesting prey is unsupported, we conclude that S. regia is not carnivorous. Instead, we propose the glandular trichomes on the S. regia calyx provide a passive defensive benefit to the flowers and seeds by protecting the very structures that are supporting their development.

ABSTRACT. Frontenac Provincial Park is located on the Frontenac Axis, a southern extension of the Canadian Shield, linking Algonquin Park to the Adirondack Mountains. To better understand the lichen biota of this interesting ecosystem, an inventory was conducted during several field visits from 2016–2019. During these surveys, 280 species of lichens and allied fungi in 115 genera were discovered. Presented is the first published record of Lempholemma cladodes (Tuck.) Zahlbr. in Canada, as well as the first published discoveries of Cladonia petrophila R. C. Harris, Coccocarpia palmicola (Spreng.) Arv. & D. J. Galloway, and Leprocaulon adhaerens (K. Knudsen, Elix & Lendemer) Lendemer & B. P. Hodk. in Ontario. Sixteen species are provincially ranked as critically imperilled (S1, S1S2 or S1S3), sixteen species as imperilled (S2 or S2S3), and nineteen species as vulnerable (S3 or S3S4). Unranked species reported for the second time in Canada are Dermatocarpon muhlenbergii (Ach.) Müll. Arg. and Cladonia atlantica A. Evans. An undescribed species of Lempholemma growing on flooded deciduous tree bases in vernal pools was also discovered. A discussion of Lobaria pulmonaria (L.) Hoffm., a pollution and habitat disturbance sensitive species, is presented. The records of L. pulmonaria discovered in Frontenac quite possibly represent the most southern observations in the province and are of conservation concern. It is recommended that a lichen awareness and education program be created for the park staff and visitors to highlight these rare and sensitive lichens and habitats within the park in the hope that lichens are protected through appropriate management and planning.

We report that a small, naturalized population of Euphorbia serpillifolia Pers. was discovered in Grand Isle County, Vermont, in 2015, a new state record. It has persisted and was vouchered by JGM in 2018. The population is growing on disturbed limestone boulders and gravel of a boat launch along the shoreline of Lake Champlain below West Shore Road just north of Eagle Camp Road in South Hero, Vermont. The range of Euphorbia serpillifolia is mostly west of the Mississippi River (Berry et al. 2016), though Gleason and Cronquist (1991) note that it is occasionally introduced eastward. While occasionally present in New York and Eastern Canada (Berry et. al. 2016; USDA 2019), in New England the species has only been reported naturalized in Gorham, Coos County, New Hampshire (Haines 2011; Pease 1964). The only known voucher records of E. serpillifolia in New England are one collected from a garden (not naturalized) in 1911 in Middlebury, Vermont, (The Pringle Herbarium [VT], UVMVT079518) that was not included by Gilman (2015), and a collection from 1917 mentioned by Pease in his book (ASP 17087; The New England Botanical Club Herbarium [NEBC] 00754933; Pease 1964). This Pease specimen is currently cataloged as Chamaesyce glyptosperma (Engelm.) Small, which accounts for Angelo and Boufford (2014) noting that no voucher was known for E. serpillifolia in New England. However, we believe that Pease was correct in his identification, based on leaf serrations more typical of E. serpillifolia. The population in Vermont was confirmed as Euphorbia serpillifolia by Nathan Taylor. Approximately 20 plants were observed in August 2018, in an area of ~15 3 20 m. The population has spread from a

This Pease specimen is currently cataloged as Chamaesyce glyptosperma (Engelm.) Small, which accounts for Angelo and Boufford (2014) noting that no voucher was known for E. serpillifolia in New England. However, we believe that Pease was correct in his identification, based on leaf serrations more typical of E. serpillifolia. The population in Vermont was confirmed as Euphorbia serpillifolia by Nathan Taylor. Approximately 20 plants were observed in August 2018, in an area of ~15 3 20 m.

ABSTRACT. This is the first checklist of Maine mosses since the publication of the state bryoflora, Maine Mosses. The checklist lists and ranks the 455 taxa of mosses that have been collected in Maine. This includes collections cited in Maine Mosses and/or the Tropicos Database of the Missouri Botanical Garden (denoted by M). These collections have been verified by Bruce Allen, Lewis Anderson, or Richard Andrus. Literature reports cited in Maine Mosses are denoted by m. Also included are collections in the database of the Consortium of North American Bryological Herbaria (denoted by r). The identity of these latter collections is mostly unverified with the exception of the Sphagnum. An * denotes species not yet found in Maine but expected to occur there.
