148	2020-05-21 08:08:15		Vascular Plants: Ferns and Lycophytes	Pteridaceae	33423	Adiantum aleuticum		species		N	N	N	N	N	N	N	Native	Occurring on both sides of the Cascades crest in Washington;	{"Herbarium":"WTU"}	The combination A. aleuticum var. subpumilum has been published (Alverson, American Fern Journal, 100(4):230-233. 2010), so the full combination here can be var. aleuticum if one recognizes the distinctiveness of var. subpumilum.<br><br>FNA2: "Although the western maidenhair has traditionally been interpreted as an infraspecific variant of Adiantum pedatum , the two taxa are reproductively isolated and differ in an array of morphologic characteristics. Therefore, they are more appropriately considered separate species (C. A. Paris and M. D. Windham 1988). Morphologic differences between A . pedatum and A . aleuticum are subtle; the two may be separated, however, using characteristics in the key. Adiantum aleuticum occurs in a variety of habitats throughout its range, from moist, wooded ravines to stark serpentine barrens and from coastal cliffs to subalpine boulder fields. Although morphologic differences exist among populations in these diverse habitats, they are not consistent. Consequently, infraspecific taxa are not recognized here within A. aleuticum."

D.C.  Eaton from the Olympic Peninsula (VPPN1) have not been confirmed by FNA or Buckingham et al. (1995).<br><br>FNA2: "Cheilanthes feei is an apogamous triploid of unknown parentage. It has small, beadlike blade segments similar to those of subg. Physapteris , but most morphological characteristics suggest a clear relationship to members of subg. Cheilanthes (T. Reeves 1979). The species is most often confused with C . parryi , from which it can be distinguished by its thinner, sparser pubescence and smaller ultimate segments."

The leaves are easily detached, and many herbarium specimens consist of separate leaves and stems, the latter covered with petiole bases of approximately equal length."

Isozyme studies (G. J. Gastony 1988) indicate that P . glabella subsp. missouriensis was the diploid parent of plants found in Missouri, whereas diploid P . glabella subsp. occidentalis was involved in the origin of P . gastonyi populations occurring in western North America. Pellaea gastonyi is most often confused with P . atropurpurea , from which it differs in having sparsely villous rachises, smaller ultimate segments, and spores averaging more than 62 Âµm in diameter."

A. F. Tryon (1957) and D. B. Lellinger (1985) hypothesized that it might have arisen as a hybrid between the western diploid member of the P . glabella complex (here called subsp. occidentalis ) and P . atropurpurea . G. J. Gastony (1988) has shown conclusively, however, that P . glabella subsp. simplex is an autopolyploid derivative of subsp. occidentalis and does not contain genes contributed by P . atropurpurea."

This subspecies comprises a complex of morphological, cytological, and phytochemical variants, at least some of which may deserve formal taxonomic recognition, following more detailed studies. Plants with yellow farina reported from Arizona, Nevada, and Utah may represent tetraploid hybrids between P . triangularis subsp. triangularis and P . triangularis subsp. maxonii and are not mapped herein."

Zika	Vascular Plants: Ferns and Lycophytes	Pteridaceae	33975	Pteridaceae		family		N	N	N	N	N	N	N	Native			FNA2: "Considerable disagreement exists concerning the circumscription and proper name of this family. The taxa comprising the Pteridaceae in this treatment were assigned to the Sinopteridaceae and Pteridaceae by D. B. Lellinger (1985) and were included in five families by R. E. G. Pichi-Sermolli (1977). The broad concept followed here is similar (except for the exclusion of Ceratopteris ) to that espoused by R. M. Tryon and A. F. Tryon (1982), who applied the name Pteridaceae to the group. Until very recently, the newer name Adiantaceae was more commonly used.<br><br>As represented in North America, Pteridaceae comprise three major evolutionary lines (the adiantoids, the pteroids, and the cheilanthoids). Characteristics holding the family together include abaxial (usually submarginal) sori that lack indusia or are protected by a reflexed or revolute leaf margin, spores that are usually globose-tetrahedral and trilete, and chromosome base numbers of 30 or 29 (rarely 27). The xeric-adapted members of the family (particularly the cheilanthoids) have undergone extensive parallel and convergent evolution, and they have frustrated attempts to produce a natural generic classification based on macromorphologic characteristics alone. Although some workers have aggregated species into a few large genera (e.g., J. T. Mickel 1979b), most tend to recognize smaller segregate genera based on a combination of morphologic, chromosomal, and biochemical data. The latter approach seems to provide a more useful, evolutionarily informative classification and is the one adopted here. Aspidotis and Notholaena are maintained here as distinct from Cheilanthes , and three recently described genera ( Argyrochosma , Astrolepis , and Pentagramma ) have been incorporated into the treatment. The reasons for these changes in generic circumscription are discussed under the individual genera."
