INTRODUCTION 5
INTRODUCTION
My interest in the pteridophytes of Costa Rica, Panama, and the Choc6 began
as a result of helping to teach a fern course in Costa Rica offered by the
Organization for Tropical Studies in the summer of 1967. In preparing for the
course, I compiled most of a checklist of the pteridophytes of Costa Rica based on
specimens present in the U. S. National Herbarium. Later, in attempting to
identify specimens collected during the course, it became obvious that the
checklist was incomplete, that few adequate monographic works were available to
aid in identification, and that a modern pteridophyte Flora was vitally needed for
the region.
. The pteridophytes of the area are as diverse as the landscape; I recognize about
1100 taxa in 117 genera, and new species or species new to the area still are
discovered from time to time. Species that became known to me after the plates
were assembled (e.g., 137a Llavea cordifolia) are given "a" numbers. They and a
few others are not illustrated. Judging by the rate of discovery, the Flora appears
to be at least 90% complete. The relatively little-known Atlantic slope of the
mountains from Central Costa Rica to central Panama is most likely to yield new
discoveries and should have first priority in future exploration.
The Nicaraguan border with Costa Rica was chosen as the northern boundary
for the Flora because Nicaragua lacks the high mountains that characterize Costa
Rica and western Panama. As Costa Rica is phytogeographically continuous with
Panama, so is eastern Panama with adjacent Colombia. To find a natural
southern limit for the Flora, Prof. Elias R. de la Sota, of the Museo de La Plata,
La Plata, Argentina, and I undertook a survey of Choco pteridophytes in
January -March, 1971. We gathered what data we could from other pteridophyte
collections and made several collecting trips to diverse sites, mostly in the
northern half of the Depto. del Choco. We found that the Choco pteridophyte
flora changed rather abruptly at an elevation of 1000 m in the Andes Mountains to
the east of the Choco basin, and so this was taken (with the Golfo de Urabd and
the drier regions to the east and the perpetually wet regions to the south beyond
the Rio Calima in Depto. El Valle) as the limit of the Flora (Lellinger, 1975).
Although these boundaries do not coincide precisely with those of the Depto.
Choco, they do come fairly close. Tallies of the species of pteridophytes found in
the Choco and in Panama and other countries and island groups of the western
hemisphere also show that the pteridophytes of Costa Rica, Panama, and the
Choc6 are a coherent phytogeographic group (Lellinger, 1975, 1985). Cocos
Island, a possession of Costa Rica far from the mainland, is not treated in this
Flora (see G6mez P., 1975a, b).
Many species of pteridophytes are quite restricted in the elevations at which
they will grow; coastal and lowland habitats versus montane habitats is a
fundamental and useful distinction to make. The lowland ferns (up to 500 m
elevation) tend to be widespread, ranging as far as southern Mexico and Brazil.
The montane ferns (500-1500 m or greater elevation) are often more restricted in
distribution and are more likely to be endemics. The richest pteridophyte areas
are the undisturbed saddles between mountains from central Costa Rica to
western Panama at mostly 1000-1500 m elevation, where cloud-borne moisture
6 INTRODUCTION
from the Caribbean refreshes the epiphytic ferns almost daily, even during the dry
season. Any lengthy dry season, as in the northern half of the Choco, makes it
impossible for most epiphytes to grow, and so severely limits their diversity.
Throughout the Flora area, species diversity is greatly diminished in secondary
forests, even those in good condition that are often thought to be primary forests.
The diversity of ferns and fern-allies in primary forests is at least twice that in old
secondary forests in good condition. Many of the rare epiphytes in such genera as
Elaphoglossum are known only from old collections. It may well be that some did
not survive cutting of the primary forests and are now extinct. The best hope for
rare species lies in preserving large tracts of undisturbed forest, as is being carried
out on an unprecedented scale by the people of Costa Rica.

My aim has been to produce a Flora especially useful for identification and
curation. Therefore, I emphasized the keys, generally using two or more
characters in each couplet to make each choice more certain. In addition, I tried
to include all names based on New World types, and so the synonymies are
extensive and will be useful widely. Specimens wrongly named or placed under
synonyms in herbaria are an impediment to rapid and careful taxonomic work.
This book is arranged in part taxonomically, with few exceptions according to
the generic arrangement of Crabbe, Jermy, and Mickel (1975), so that related
families and genera fall close together (see List of Families, Genera, and
Subgenera or Sections). The accepted taxa are given serial numbers and virtually
all, except for the late additions, are illustrated to enable the reader, after using
the keys, to confirm the identification without reference to a herbarium, although
a herbarium should be consulted if one is available. The taxa are arranged
alphabetically within the genus (or in large genera, within subgenera) in order to
group related taxa and their illustrations together. I have tried to adopt generic
concepts that are useable by non-specialists and to avoid both microgenera that
are difficult to distinguish (e.g., in the Hymenophyllaceae) and composite genera
that contain readily distinguishable and presumably related groups of species that
can stand as genera (e.g., in the Polypodiaceae). The family descriptions are not
inclusive but concentrate on the characteristics of the genera and species of each
family that are found in the Flora area. I have adopted the name Tectariaceae to
replace the illegitimate and unconservable Aspidiaceae, which has in addition
been used formerly in a much broader and confusing circumscription; the name
Pteridaceae, which was incorrect when published because it included types of
earlier published family names, but which is correct in a narrow circumscription;
and the names Adiantaceae, Dicksoniaceae, and Dryopteridaceae, all of which
have recently been accepted for conservation by the Committee for Pteridophyta.
The genera are numbered sequentially throughout the Flora. These numbers
are used in the keys to the families and to the genera and also appear in the
running heads so the reader can turn readily from the keys to the generic
treatments. Likewise, all species and infraspecific taxa are numbered sequentially
so that the reader can turn readily from the keys to the text to the illustrations.
Those species and infraspecific taxa with a letter following the number are mostly
not illustrated.
Illustrations are based on specimens in the U. S. National Herbarium (US),
unless otherwise noted by another herbarium acronym. They are based on
specimens from the Flora area, unless another countiy is noted, ’^^en the country
is designated as Colombia, the specimens illustrated are not from the Choco. All
bar scales are 1 cm long, except as noted. Scales referring to two or more
illustrations are centrally placed and have full cross-bars at the ends. Those
referring to a single figure are placed near that figure and have half bars at the
ends.
Many pteridophytes, because of wide ranges, have accumulated many scientific
names. To save space and to prevent this Flora from being unwieldy, I have cited
only basionyms in the synonymies, but not transferred names having parenthetical
authors. Transferred names, at least for most species, are listed in the “Index
Fiiicum” (Christensen, 1905 “1906, 1913, 1917, 1934; Pichi Sermolli et ah,
8 INTRODUCTION
Map of Panama
INTRODUCTION 9
1965; Jarrett et al., 1985). Furthermore, I have replaced descriptions of the
species and infraspecific taxa with augmented keys; one or more phrases
describing the taxon may follow the strictly contrasting information in each portion
of the key that leads to a species or other infraspecific taxon. For the same
reason, specimens are cited only of the rarest taxa, in order to document their
presence in the Flora area. Some of the uncited specimens I have seen are in an
unpublished, largely typewritten data base that I used in preparing the Flora.
Literature cited in synonymies conforms largely to standard usage (Lawrence et
al., 1968; Stafleu & Cowan, 1976-1988), with some amplifications so that the
citations are intelligible without recourse to the standard works. I have included
page numbers (but not dates, even if they are different) for some widely held
reprints (Mettenius in Triana & Planchon, 1864; K. Presl, 1845a, 1851; Sodiro,
1897) and postprints (Presl, 1843, 1845b, 1847). I have also included some widely
held alternate titles, such as Fee’s memoir series, Jenman’s treatment of the ferns
and fern allies of Jamaica, Spring’s monograph of Lycopodium, and Domin’s
treatment of the pteridophyta of Dominica.
Types and lectotypes of many early names are based on plates published in
three pre-Linnaean works. Plunder’s “Traite” (1693), his “Description” (1705),
and Sloane’s “Voyage” (1707-25). The full titles of these works are cited below.
In the citation of specimens (mostly types), the word photo followed by a
number refers to the numbered series of photographs taken by C. V. Morton to be
found at US and distributed to other herbaria. For the type specimens of many
collectors, the usual herbarium of deposit is given, even when I have not seen the
specimens.
Because collectors have so frequently revisited a few choice collecting localities,
I have placed these localities and the provinces of Costa Rica and Panama on
maps (pp. 6, 8, and 10). For these localities, the province is not cited in the
discussions but can be learned by examining the maps. Localities in the Flora area
are cited from northwestern Costa Rica through eastern Panama to the southern
Choco.
The ranges cited in the discussion are based on herbarium specimens, both old
and new. Insofar as collecting has been adequate, they reflect the original range
of each taxon in the Flora area. In the more settled areas of this region, the
landscape has been virtually entirely altered by agricultural and other activities,
and most of the pteridophytes can no longer be Wnd. Their preservation in large,
well protected parks and nature preserves appears to be their best chance of
survival.
Special literature, mostly relatively recent monographs and revisions, is cited
under each genus. Since this work was begun, several general works have been
published that I have consulted repeatedly in matters of taxonomy, nomenclature,
and plant distribution. ITiese are Kramer (1978), Mickel and Beitel (1988),
Proctor (1977, 1985), Smith (1981, 1985), and Stolze (1976, 1981, and 1983).
My fieldwork in the Flora area was supported by the Smithsonian Research
Foundation, the National Geographic Society, and the Organization for Tropical
Studies. Herbarium visits (to A and GH, CR, DUKE, F, MO, NY, PMA, and UC)
were supported by the Smithsonian Institution. Preparation of the illustrations
was entirely supported by the Smithsonian Research Foundation and by the

these organizations. I am indebted to my colleagues D. S. Barrington (for the
treatment of Polystichum), L. E. Bishop, M. D. Correa A., F. R. Fosberg, L. D.
Gomez P., R. J. Hickey, R. E. Holttum, J. T. Mickel (for the treatment of
Elaphoglossum), J. D. Montgomery, R. C. Moran, the late C. V. Morton, D. H.
Nicolson, B. 011gaard, R. L. Petersen, G. R. Proctor, H. E. Robinson, A. R. Smith
(especially for his meticulous reading of the entire manuscript), R. G. Stolze, A. F.
Tryon, R. M. Tryon, Jr., W. H. Wagner, Jr., H. van der Werff, P. G. Windisch, and
J. J. Wurdack, for lending specimens or for help with problems of taxonomy and
nomenclature. Mary Monsma prepared the illustrations over a period of many
years, except for the drawings of Elaphoglossum scales done by Alice Tangerini;
and Brian Kahn, Gregory McKee, and Alice Tangerini assembled and lettered the
plates and prepared the maps. I am grateful for their work, which has added so
much to the usefulness of the Flora. Ellen Farr and Robert Sims provided much
needed advice on data bases and desk-top publishing, and Gregory McKee also
assisted with the desk-top publishing, for which I am most thankful.

LYCOPODIACEAE
Monotypic in this treatment; see description oi Lycopodium.
2. LYCOPODIUM L.
Plants terrestrial or epiphytic; rhizomes very short and inconspicous or wide-
creeping and conspicuous, provided with tufts of dichotomously branched roots at
the nodes and with sparse leaves; aerial stems simple, dichotomously branched, or
apparently pinnately branched, usually glabrous, seldom hairy, the leaf-like
appendages arranged in a series of spirals, minute or not, 1-nerved, mostly linear,
narrowly lanceolate, or narrowly lanceate, all alike or the fertile ones slightly to
greatly different, often forming discrete strobili; sporangia axillary, sessile or short-
stalked, yellow, reniform or subglobose; spores of 1 kind.
Pantropical with some temperate species; ca. 500 species. The infrageneric
taxonomy of this genus has not yet been settled, and many tropical species are
poorly known. The subgenera adopted here follow 011gaard’s concepts, which
emphasize branching patterns and spore morphology.

I separate as var. aristatum the tropical American specimens, which are large
and coarse, compared to the north temperate specimens of var. clavatum. Variety
aristatum hybridizes with L. contiguum in the northern half of the Cordillera de
Talamanca and on Volcan Chiriquf. The hybrids have one or more sessile strobili
terminating upright branches, and the rhizomes may be hypogeous or epigeous.

However, Hb. Juss. no. 668, labelled “magellan... Commerson” is L. confertum Willd., whereas no.
669, without collector or locality and labelled both L. magellanicum and L. confertum, is true L.
magellanicum. I suspect that Palisot was sent part of 669, which I assume should bear the same
locality and collector as 668.
Plants terrestrial, at 3300-3800 m, in paramos, in the Flora area known only
from Cerro Chirripo, Pcia. S. Jose {Evans & Lellinger 182, US). Also from

TYPE: Martinique, J. Martin (P-Hb. Lam. 442 not seen), cited by Underwood
and Lloyd (Bull. Torrey Bot. Club 33: 104. 1906).
Plants terrestrial, at 600-3300 m elevation, on wet banks or occasionally on
rotting tree trunks, mostly in open areas, from the Cordillera Central, near
Puriscal (Pcia. S. Jose), and the Cordillera de Talamanca to Pcia. Code. Also
from the Antilles, Trinidad, Mexico to Bolivia, Brazil, and Paraguay.
This species is related to L. hojfmannii and may hybridize with it. Proctor
(Rhodora 68:464. 1966) recognized L. reflexum var. rigidum (J. F. Gmel.) Proctor
from Jamaica, Hispaniola, and several islands in the Lesser Antilles.

Argentina.
Rolleri (Revista Museo La Plata, Secc. Bot. 13:79. 1981) has ascribed L.
capellae (Herter) Morton to Costa Rica on the basis of one specimen from Cerro
Asuncion, Pcia. S. Jose {de la Sola 5048, LP), which I have not seen. Lycopodium
capellae differs from this species in having sporophylls shorter and wider than the
sterile leaves and in having the leaves thinner and less appressed to the stems.
011gaard (pers. comm.) is of the opinion that true L. saurunis does not occur north
of Peru. If so, this species may be without a correct name in the Flora area.

is a new species because the name L. panamense Willd. is unpublished, but it is also superfluous
because L. brongniartii Spring is cited in synonymy.
Urostachys costaricensis Herter, Amer. Fern J. 48:83. 1958. TYPE: Costa Rica, Mar 1908,

Ecuador, and Brazil.
This species differs only slightly from L. tuerckheimii Maxon (Contr. U. S. Natl.
Herb. 13:23. 1909). The only difference I have seen is that the sporophylls of L.
tortile are often much shorter than the sterile leaves, a condition much less marked
in L. tuerckheimii. If the two are united, L. tortile has priority by a few days.

42 LYCOPODIACEAE: 2. LYCOPODIUM
LYCOPODIACEAE; 2. LYCOPODIUM 43
This variety is slightly distinct from typical material from Reunion in its shorter,
more spreading sterile leaves. It differs from L. tortile in having thinner, laxer, less
appressed sterile leaves, particularly at the base of the stems. 011gaard in Stolze
(Fieldiana, Bot. N.S., 12:32. 1983) considers this to be a species distinct from the
Old World L. verticillatum and calls it L. acerosum Swartz. Specimens from Sitio
Birds, Pcia. Cartago [?] {Pittier 191, US) and Volcan Chiriqui {Davidson 1021, US)
look much like L. verticillatum var. parvifolium but may prove to be a variety of L.
tenue Willd., according to B. 011gaard (in litt.).

Plants epiphytic, at 900-2700 m elevation, in forests, from Los Angeles de S.
Ramon (Pcia. Alajuela), the Cordillera Central, and the Cordillera de Talamanca

This species has pendent stems up to 10-times branched. The sterile leaves are
more spreading than are those of L. verticillatum W3X. parvifolium, which are clearly
ascending.

Martinique, and Mexico to Venezuela and Ecuador.
011gaard in Stolze (Fieldiana, Bot. N. S., 12:43-44. 1983) has united L.
stamineum with L. wilsonii. The plants of the former species tend to have
narrower leaves with reddish bases, but the coloration may be inconstant and
specimens of the latter with narrow leaves matching those of L. stamineum are
known.

44 SELAGINELLACEAE: 3. SELAGINELLA
SELAGINELLACEAE
Monotypic; see description of Selaginella.
3. SELAGINELLA Pal. Beauv.
Plants terrestrial, occasionally epipetric, rarely hemiepiphytic or epiphytic;
stems mostly prostrate and long-creeping, ascending, or erect, rarely caespitose,
branched, ca. 0.5-3 mm in diam., often articulate, usually stramineous or
greenish, often sulcate, bearing often long, wiry, dichotomously branched roots
from the axils of the branches and bearing numerous, small, 1-nerved, usually
ovate or lanceolate, often aristate and ciliate or denticulate leaves, the leaves
monomorphic, crowded, and spirally arranged around the stems or dimorphic,
usually not crowded, and arranged in 2 small, dorsal, appressed ranks and 2
ventral, larger, usually spreading ranks; sporophylls usually monomorphic, slightly
modified, aggregated into usually rather loose terminal strobili; sporangia solitary
in the axils of the sporophylls, the megasporangia bearing 1-4 large, pale, trilete
megaspores, the distal microsporangia bearing many, much smaller, often orange,
trilete microspores.
Pantropical with some temperate and xerophytic species; ca. 700 species.
Selaginella is usually divided into subg. Selaginella, with uniform, spirally arranged
leaves, and subg. Stachygynandrum (Pal. Beauv.) Baker, with dimorphic leaves
arranged in 4 ranks. (Only the latter is represented in the Flora area.) Hellwig
(1969) found that spore characters support the subgeneric classification and point
toward a classification below that level. However, additional characters, such as
habit and stelar structure, need to be taken into account. Some species of
Selaginella are attractive plants in tropical gardens and in greenhouses, especially
S. pallescens, with white-margined leaves, S. umbrosa, with red stems, and S.
exaltata, a large, scrambling species with ample, feathery branches.

SELAGINELLACEAE: 3. SEU\GINELLA 49
Plants terrestrial, at 0-1000(1700) m elevation, in or at the edges of forests,
often covering large areas, from throughout the Flora area. Also from Venezuela
to Bolivia.
46. Selaginella arthritica Alston, Arch. Bot. Sist. 11:43. 1935.
TYPE: Golfo Dulce, near Puerto Jimenez, Pcia. Puntarenas, 30 m, Cufodontis

Plants terrestrial, at 0-900(1200) m elevation, in forests, throughout Costa Rica
and Panama and from the Rio Nuqui, Depto. Choc6 (Haught 5460, BM, US).
Also from Nicaragua and Colombia.
This species has both a prostrate, juvenile, usually sterile phase with upright
branches up to ca. 8 cm long and an arborescent, mature, fertile phase with
upright branches over 30 cm long. Although the two phases are completely unlike
in habit, the leaves of both are similar in their details. Occasionally the lateral
branches of S. arthritica become abnormally long and bifurcate, bud, or root at the
apex.

Plants terrestrial, at 0-2400 m elevation, in forests, from scattered localities in
the Cordillera Central and the Atlantic coastal plain through the Choco. Also
from Venezuela to Peru.
This species exists in a low-altitude (up to ca. 600 m), rather erect growth form
and in a high-altitude, creeping form. The leaves in both forms are variable,
especially in marginal cilia length and in the width of the whitish, marginal band
around the leaves. Neither of these characters correlates with habit. Bruce
McAlpin (pers. comm.) found that the two forms maintained themselves under
conditions of uniform culture. Although it is possible that two species are
involved, I have not been able to separate the specimens by any character other
than habit.

70 ISOETACEAE: 4. ISOETES
ISOETACEAE
Monotypic; see description of Isoetes.
4. ISOETES L.
Plants aquatic, amphibious, or terrestrial in vernal pools, rooted in mud or
sometimes gravelly soil; roots and leaves borne on 2- or 3-lobed, erect, usually
subterranean, indeterminate, globular, corm-like stems; roots rather fleshy, borne
in longitudinal lines on the outer and basal faces of the corms; leaves rush-like,
erect or spreading, crowded, borne on the apical and outer surfaces of the corms,
triangular or terete, with an unbranched midrib, 0- several longitudinal strands of
thickened supporting cells, and longitudinal air chambers divided by lateral
septae; fertile leaves swollen at the base, bearing an adaxial, embedded
sporangium often partially or entirely covered by a scarious velum and a usually
triangular ligule just distal to the sporangium; sporangia of 2 types, the
megasporangia bearing a few large, spherical, white, often highly ornamented
megaspores, the microsporangia bearing many minute, usually ellipsoid, tan
microspores.
Widespread in temperate and tropical regions; ca. 100-200 species. The genus
is the only extant representative of the Lycopsida subclass Isoetidae, which has a
long fossil record. Tlie peculiar morphology of Isoetes has made it the object of
much study (Karrfalt, 1980; Paolillo, 1963). Some of the species show
physiological adaptations to their hot and sunny habitat (Keeley, 1981). The
taxonomy of this genus is difficult but is made easier through examination of
mature spores with the scanning electron microscope. The tropical American
species of the genus are currently under study by H. P. Fuchs-Eckert (1982) and R.
J. Hickey (1986). According to Hickey (pers. comm.), the upland populations of
southern Central America all differ slightly from one another, as do the lowland
ones, and it is best to treat each of the two groups as a single species, rather than
to name several populations of each as separate species.

72 EQUISETACEAE: 5. EQUISETUM
EQUISETACEAE
Monotypic; see description of Equisetum.
5. EQUISETUM L.
Plants terrestrial, often in wet places; rhizomes subterranean, blackish, wide-
creeping with wiry roots, branched, bearing erect stems at their nodes; erect stems
cylindrical, hollow, unbranched or with few to many branchlets in a whorl at some
or all nodes; erect stems and branchlets gray-green, hollow between the nodes,
slightly fluted, tough and harsh from silica deposited in the cell walls; leaves
reduced, connate laterally to form nodal sheaths with often scarious and deciduous
distal teeth; sporophylls highly modified (peltate) and aggregated to form strobili
terminal on the branches or branchlets; sporangia ca. 6 per sporophyll, dehiscent
adaxially; spores of 1 size, spherical, greenish, bearing 4 hygroscopic, coiled bands
(elaters).
Widespread in temperate and to some extent tropical regions; 15 species plus
many interspecific hybrids. The genus is the only extant representative of the
ancient class Equisetopsida, which was especially conspicuous in the
Carboniferous. The taxonomy of the genus has been well worked out by Hauke,
but the identification of individual specimens remains difficult because of the
minute characters and the frequent interspecific hybrids.

76 OPHIOGLOSSACEAE: 6. BOTRYCHIUM
OPHIOGLOSSACEAE
Rhizomes subterranean, short and erect or rarely globular, glabrous, bearing
fleshy roots lacking root hairs and 1-few fronds; fronds small, brittle, not
circinate, partially dimorphic; stipes fleshy; laminae papyraceous to subcoriaceous,
the sterile portion simple or forked to 3-pinnate, the usually erect fertile portion
greenish or yellowish, unbranched and bearing 2 rows of sunken sporangia or
branched several to many times and bearing 2 rows of short-stalked sporangia;
sporangia globular, lacking an annulus, dehiscing transversely; spores trilete,
numerous (more than 1,000 per sporangium).
1. Sterile portion of the laminae 2-3-pinnate, more or less deltate, with free veins; fertile portion
of the laminae pinnately divided.
6. Botrychium
1. Sterile portion of the laminae simple or furcate, not deltate, with anastomosing veins; fertile
portion(s) of the laminae simple.
7. Ophioglossum
6. BOTRYCHIUM Swartz
Plants terrestrial, in meadows and pastures or occasionally in forests; rhizomes
subterranean, erect, short, bearing fleshy roots at the base and usually a single
frond near the apex; buds of new fronds protected by the sheathing base of the old
frond, the laminae when young folded, not circinate; fronds glabrous, partially
dimorphic; sterile portion of the laminae expanded, 2-3-pmnate, spreading,
yellow-green or bright green, the lamina subternate, the venation free; fertile
portion of the laminae contracted, 1-3-pinnate, erect, yellow, bearing short-
stalked, globular sporangia.
Widespread in temperate regions, with some tropical representatives; ca. 35
species. The species of Botrychium are subtle and their characters tend to be
variable, all of which causes considerable difficulty in identifying them. The genus
is being monographed by W. H. Wagner, Jr., who has combined herbarium and
field studies to arrive at far better species concepts than were formerly known.

7. OPHIOGLOSSUM L.
Plants terrestrial, in meadows and pastures (subg. Ophioglossum) or epiphytic
on tree trunks in wet forests (subg. Cheiroglossa); rhizomes subterranean, erect,
short, rarely globose, bearing fleshy roots at the base and 1-few fronds near the
apex; fronds glabrous, not circinate, partially dimorphic; sterile portion of the
laminae expanded, simple (furcate in subg. Cheiroglossa), pale to dark green, the
venation irregularly areolate, sometimes with finer veins dividing the major
areolae into yet smaller ones; fertile portion of the laminae (1 in subg.
Ophioglossum, several in subg. Cheiroglossa) contracted, simple, erect (in subg.
Ophioglossum) or pendulous (in subg. Cheiroglossa), bearing 2 rows of globular
sporangia partially embedded in the tissue.
Widespread in temperate and tropical regions, but nowhere common; ca. 25
species. These reduced plants have few characters, and they are variable. The
sterile, expanded portion of the laminae is peculiar in lacking a midrib. Species
delimitation in Ophioglossum may be difficult; size is not a reliable character, and
venation is sometimes influenced by size.

19. ALEURITOPTERIS Fee
Plants terrestrial or epipetric, in seasonally dry, open areas; rhizomes erect or
ascending, scaly, the scales linear-lanceate, weakly bicolorous, the margins entire;
fronds medium-sized, largely lacking hairs or scales; stipes brown, reddish-brown,
or atropurpureous, shiny, slightly scaly, especially at the base, terete; rachises
resembling the stipes in color; laminae 1-2-pinnate- pinnatifid, commonly
lanceolate, rather coriaceous, copiously farinose on the abaxial surface, the basal
and suprabasal pinnae strongly basiscopically produced; pinnae lanceate, the
pinnules elongate, lobed, with continuous, wide, membranaceous, brownish
marginal indusia; veins free, simple or forked, hidden within the lamina tissue; sori
laterally confluent, at the tips of veins; sporangia short-stalked.
Tropical and subtropical subxerophytes, all but one exclusively in the Old
World; ca. 15 species. This genus is sometimes considered to be a synonym of
Cheilanthes, and some apparent species of Cheilanthes do resemble species of
Aleuritopteris, but the similarities presumably are due to convergence.

Punta and near David (both Pcia. Chiriquf). Also from Jamaica, Hispaniola,
Mexico, Guatemala, and Peru.
This species, which is fairly common in Mexico, is rare in the Flora area.
Apparently it is becoming more widespread and frequent as drier habitats appear
due to deforestation and climatic change.

Plants terrestrial, at (2100)2700-3400 m elevation, in high montane and
paramo regions, from the Cordillera de Talamanca.
A. F. Tryon (1970, p. 162) considered this to be a variant of E. flexuosus, which it
may be, although it differs from typical material of that species in the shape of its
ultimate segments as well as in its pubescence. Scamman (Contr. Gray Herb.
191:88. 1962) maintained E. villosulus as a distinct species, principally because it
usually grows at higher elevations than does typical E. flexuosus. Some or all of
the specimens of E. villosulus may be hybrids between E. flexuosus and E. congestus
or, because they resemble E. flexuosus in lamina architecture, may be backcrosses
between such a hybrid and E. flexuosus.

putative parents, sharing the lamina scales of A. obliquum and the pinna shape and
rhizome scales of A. petiolatum. They are also intermediate between these two
species with respect to pinna number and marginal lamina serrations.

ADIANTACEAE: 32. ADIANTUM 151
Plants terrestrial, at 0-500 m elevation, from the Pacific lowlands of central
Costa Rica. Also from Peru, Bolivia, Brazil, and Argentina.
The name A. pectinatum Kunze ex Ettingsh. (Farnkr. Jetztw. 85, t. 45, f. 14-16.
1864) must be considered a nomen nudum because there is no description and the
three figures are coordinate, each being a pinna; therefore there is no “illustration
with analysis” to validate the name.

Weatherby or Tryon.
Plants terrestrial, at 0-600 m elevation, in forests, from throughout the Flora
area. Also throughout tropical America.
This species occasionally has long-creeping rhizomes with rather widely spaced
stipes (ca. 1 cm); in this character it mimics A. latifolium. Intermediates exist
between the specimens with ovate or lanceolate fronds bearing few lateral pinnae
and those with oblong laminae bearing many pairs of pinnae. The latter slightly
resembled, ohliquum, which see for a further comment on this species.

ADIANTACEAE: 32. ADIANTUM 153
Plants epipetric or terrestrial, at 0 - 700(1100) m elevation, in forests and
ravines, from the Peninsula de Nicoya, the Cordillera de Tilaran, the Pacific
coastal plain of northern Costa Rica, the Meseta Central, Penonome and vicinity,
and the Canal Zone. Also from Mexico to Nicaragua, Colombia, and Venezuela.
This species may be difficult to distinguish from A. tenerum; the angle of the
pinnule or segment base varies in both species. In Mexican specimens, the
segments of^. princeps are larger than are those of^. tenerum, but this difference
is less marked in Costa Rican material.

Rosenstock’s variety refers to the large form with four or five pairs of lateral
pinnae. This variant is scattered throughout the range of the species, but in
Central America it is predominantly in the southern portion of the range. There
seem to be no substantial characters to separate it from var. wilsonii.

Also from Cuba, Hispaniola, Guatemala, Belize, Guyana, and French Guiana.
This species is allied to H. brevistipes Liebm. of Mexico and Honduras, which
has the stipes narrowly alate almost to the base, and to H. abruptum Hook, of the
Greater Antilles, which has fronds that are a little larger and less divided.
280. Hymenophyllum contoitum v. d. Bosch, Nederl. Kruid. Arch. 5(3): 170. 1863.

Guatemala.
This species is closely related or possibly conspecific with the South American
H. fendlerianum Sturm in Mart. (FI. Bras. 1(2):291. 1859), which has longer and
narrower fronds with even more contorted segments that seem invariably to be the

Plants epiphytic on trunks, at (400)1000-2900 m elevation, in forests, from the
Cordillera Central, Cerro Tablazo, the Cordillera de Talamanca to Pcia. Chiriqui,
and northwest of Sta. Fe.
This species is often misidentified as H. polyanthos, but differs in having entirely
exalate stipes. However, it is possible that a few specimens from the Flora area
could be referable to H. polyanthos var. protrusum (see a comment under H.
polyanthos). The pinnae of H. costaricanum are less crowded and often its laminae
are longer and more linear than are those of H. polyanthos var. polyanthos. Two
small, sterile specimens found at 200 - 900 m elevation in the Choco {Killip 35339

H. costaricanum, but are insufficiently known to be described.

Plants epiphytic on trunks and branches, at (600)900-3300 m elevation, in
forests and open areas, from the Cordillera Central, Cerro Tablazo, the Cordillera
de Talamanca to Pcia. Chiriquf, the valley of the Rfo General, the Peninsula de
Osa, Cerro Jefe, Cerro Pirre, and the northern half of the Choco. Also from
throughout tropical America.
This species and H. nigrescens are not strongly separated, and are part of a large
and variable complex that is much in need of critical study. Proctor (FI. Less.
Antill. 2:76-77. 1977) distinguished H. polyanthos V2S. protrusum (Hook.) Farw.,
with pendent, elongate, apparently indeterminate laminae, as seen in Valerio 214
(US) from Volcdn Barba and in Michel 3220 (US) from the Cerro de la Muerte.
The tendency toward indeterminateness occurs sporadically in Costa Rican
material, and in my opinion these specimens are not worthy of taxonomic
recognition (although the Antillean ones very well may be). Therefore, I have
excuded synonyms of wdiV.protrusum from the synonymy.

surface are variable in this species. Gleichenia bradeomm and part of G. compacta
are terminal portions of laminae, whereas G. mellifera is a basal portion. The
scales on terminal portions are reddish-brown with rather long, lax setae; those of
the basal portions are darker brown and sometimes paler toward the center of the
scale, with fewer, shorter, and stiffer setae.

rhizome form it seems more allied to the other species of that genus than it does
to the species of Polypodium subg. Marginalia. If hybrids between Pleopeltis and

El Cope (Pcia. Code). Also from Ecuador.
This species is probably related to, or may even be conspecific with, the little-
known Ecuadorian Polypodium chionolepis Sodiro. The only character that sets
this species, which is the type of the genus Marginariopsis, apart from other species
of Pleopeltis is its coenosori. In venation and chromosome number (jc = 35,
according to F. Wagner, pers. comm.), it is a Pleopeltis; its rhizome scales are like
those of P. fructuosa and P. panamensis. Either of the latter species could be
considered Marginariopsis, but both lack coenosori, and P. panamensis is not
always dimorphic. Since a continuum of characteristics occurs in these three
species, generic or even infrageneric separation is not warranted for any of them.

Kunze, which is known from Nicaragua but not from the Flora area. From the
latter species it differs in having a usually dark, abaxial stipe and rachis stripe,
narrowly lanceolate-attenuate, often denticulate rhizome scales ca. 0.5 - 0.75 mm
wide, and usually segments that are contracted distal to the base. Gomez

This species commonly has been identified as large P. fraxinifolium, but differs
from that species in having adnate distal pinnae, or as P. adnatum Kunze ex
Klotzsch, but differs from that species in lacking adnate proximal pinnae. It is also
close to the Andean P. caeceresii Sodiro, but differs in having broader, distinctly

POLYPODIACEAE: 55. POLYPODIUM 289
Wagner, Wagner, and Gomez (Brenesia 12/13:81 - 103. 1977) indicate that this
species usually is diploid through much of its range, but is commonly tetraploid
between Tres Rios and Cartago, which accounts for its ability to hybridize with P.
friedrichsthalianum to form P. aspidiolepis in that area. Wagner & Wagner (Fern
Gaz. 11:125-135. 1975) have found that this species also hybridizes with
Pleopeltis macrocarpa var. macrocarpa to form Pleopeltis xleucospora. In the Flora
area this hybrid is known from the crater of Volcan Irazu (O. Jimenez 1155, US).

Guatemala, Venezuela, Colombia to Peru, and Surinam.
This species is rather variable in frond form throughout its extensive range.
Specimens from the Choco differ from those of the remainder of the range in
being sparsely hairy on the axes, veins, and lamina surfaces, like P. chnoophonim
Kunze. But they differ from that species in having laminae that are dark green,
truncate, and fully pinnate at the base.

298 POLYPODIACEAE: 57. GRAMMITIS
57. GRAMMITIS Swartz
Plants mostly epiphytic, occasionally epipetric or on fallen logs; rhizomes mostly
short-creeping to erect, conspiculously to inconspicuously scaly or rarely glabrous,
the scales lanceolate, clathrate or not; stipes obsolete to longer than the laminae,
wiry, inconspicuously articulate, not scaly or scaly only at the base, often long-
setose throughout; fronds minute to medium-sized, monomorphic or rarely slightly
dimorphic; laminae simple to pinnatisect (rarely more divided in sect.
Cryptosorus), mostly linear, oblong, or elliptic, glabrous, sparsely setose, pilose, or
pilosulous, or rarely glandular, the setae stiff to lax, short to long, mostly reddish-
brown, sometimes confined to the sori; veins unbranched, forked, or pinnate,
rarely irregularly anastomosing with a few included veinlets; sori terminal on a
vein or vein branch, superficial or occasionally impressed, round or rarely oblong,
exindusiate; paraphyses present or absent; sporangia long-stalked; spores trilete,
commonly greenish.
Pantropical; ca. 400 species in the broad sense, including ''Cryptosorus'' and
''Xiphopteris.'' The name ''Grammitis sect.. Xiphopteris (Kaulf.) Presl” used below
is the traditional name applied to this group of plants. This name is based on
Xiphopteris Kaulf., which is a synonym of Cochlidium, and so cannot be correctly
used in Grammitis. I do not wish to coin a new sectional name because Grammitis
is being divided into several genera by L. E. Bishop and the current sectional
names and concepts are not likely to continue in use.

Plants epiphytic, at 0-300 m elevation, in forests, from the Rio S. Juan basin
and Boca Curiche (both Depto. Choco). Also from Venezuela and Colombia to
Bolivia.
This species is similar to G. blepharodes, which is an upland species, and to G.
blepharolepis (C. Chr.) Morton, which has shorter, wider, and more distant
segments. Some of the segments of G. daguensis are gibbous, and so that
character does not separate the species from G. blepharolepis very well. Most of
the Choco specimens of G. daguensis are slightly intermediate between that
species and G. blepharolepis', they have relatively shorter, less parallel-sided
segments than do specimens of G. daguensis from Pcias. El Valle and Cauca.

The American members of Dicksonia are in need of additional study; new,
perhaps chemical, data would be especially welcome. This species and D. gigantea
are not always easily separated; the largely southeastern Brazilian D. sellowiana
Hook, apparently differs in having soral paraphyses shorter than the sporangia.

Information for Contributors
Manuscripts and accompanying illustrative material must be submitted in
duplicate and should follow the format used in recent issues of PTERIDOLOGIA.
All manuscripts must be double-spaced throughout, including title, text, table,
captions, lists, literature cited, etc. Figure captions and tables must be typed on
sheets separate from the text. All measurements should be given in S. I. (metric)
units, except for quotations and transcribed data, such as elevations on herbarium
specimens.
Line illustrations should be proportioned (including space for their captions) to
the PTERIDOLOGIA page and designed for reduction to 1/2 to 2/3 original size.
Halftone copy should be designed for reproduction at actual size. Scales and
explanations of symbols should be included in figures, rather than in captions.
Maps must include latitude and longitude references. In no case should original
illustrations be sent prior to acceptance of the manuscript. When needed, they
should be mounted on stiff board and mailed flat.
Presentation of nomenclatural matter (accepted names, synonyms, and
typifications) should follow the format used in PTERIDOLOGIA. Institutional
abbreviatons in specimen citations should follow a recent edition of Index
Herbariorum, part 1. The Herbaria of the World (Regnum Vegetabile vol. 92.
1974, or later). Abbreviations of names of journals should follow those in
Botanico-Periodicum-Huntianum (Lawrence, G. H. M. et al. 1968. Hunt
Botanical Library, Pittsurgh). Abbreviations of book titles in synonymies should
follow those in Taxonomic Literate, ed. 2 (Stafleu, F. A. and R. S. Cowan. 1976ff.
Bohn, Scheltema & Holkema, Utrecht). Abbreviations from the foregoing works
that are uninterpretable without reference to those works may be expanded. If the
correct abbreviation cannot be determined, the full title should be used, subject to
abbreviation by the editors. Titles of books cited in bibliographies should have at
least the principal title given in full, together with the place and date of
publication, name of publisher, and an indication of the edition, if other than the
first.
Additional questions regarding format should be addressed to the editor.
