MAXON—STUDIES OF TROPICAL AMERICAN FERNS. 423 
Dominica, Grenada, Santo Domingo, Cuba, Jamaica, Mexico, Guatemala, and Costa 
Rica. Not infrequently plants produce sporangia while still very small (10 cm. long, 
or less) and only once or twice dichotomous. This state was described as a new 
species, Lycopodium barbatum Christ,’ in 1905, upon a Costa Rican specimen collected 
by Wercklé, a portion of which Prince Roland Bonaparie has courteously presented 
to the U. 8. National Museum. Matching it completely are certain specimens from 
‘osta Rica (Ridgway), Nicaragua (Fliat; Wright), and Brazil (Lindman A2705); 
while a second Brazilian specimen (Malme 1664) shows a less juvenile condition 
approaching the normal form of the species. This species is unusually variable in 
the direction of its leaves, the less mature plants not being typical in this respect. 
Lycopodium wilsonii Underw. & Lloyd, Bull. Torrey Club 33: 109. 1906. 
In the original description of L. wilsonti only the type specimens (Wilson 153) 
were mentioned. There are in the U.S. National Herbarium two additional collections 
of this species, both from the type region, the Sierra Luquillo. 
Porto Rico: Sierra de Luquillo, in sylvis montis Yunque, July 18, 1885, Sin-- 
tenis 1543 (distributed as L. dichotomum). El Yunque, March, 1912, 
Hioram 383. 
Lycopodium blepharodes Maxon, nom. nov. 
Lycopodium affine Hook. & Grev. Bot. Misc. Hook. 2: 364. 1831, not Bory, 1804. 
Typr Locauity: Mount Pichincha, Ecuador (Jameson ). 
DistrisuTion: Mountains of Ecuador and Venezuela, ascending to 3,300 meters. 
This species, of which several collections from Ecuador and Venezuela are mentioned 
by Hooker and Greville and by Spring, can not retain the name affine on account of 
the earlier use of this name by Bory for a very unlike species (from Bourbon) which is 
an ally of L. carolinianum. The South American plant is accordingly here renamed 
blepharodes, in allusion to the numerous curved cilia which fringe both sporophyls and 
leaves. ‘T'wo sheeis of Ecuador specimens, both collected by Jameson, one of them 
labeled Cerro de Pichincha, are in the National Herbarium, and a third, also from the 
Quitensian Andes, collected by Jameson, is in the Gray Herbarium. These agree 
well with the descriptions by Hooker and Greville and Spring.” The habit of the 
specimens points unmistakably to an epiphytic habitat. 
The Costa Rican specimens erroneously referred to this species by Hieronymus 
are to be regarded as a new species, L. hoffmanni. 
Lycopodium hoffmanni Maxon, sp. nov. 
Plants apparently terrestrial, rigidly arcuate-ascending or erect, 25 to 40 cm. long, 
once or twice (rarely 3 times) dichotomous, the divisions erect, diverging at a very 
acute angle, continuously or discontinuously sporangiate in the apical half or two-thirds. 
Stems 2 to 3 mm. in diameter, woody; leaves and sporophyls alike, borne apparently 
in 10 ranks, ascending or mostly spreading and recurved, wholly or partially concealing 
the stem, radial, straight or nearly so, not twisted at the base, lanceolate to narrowly 
deltoid-lanceolate, 5 to 7 mm. long, 1 to 1.5 mm. broad at or just above the base, 
gradually narrower toward the acute (but not attenuate) apex, thick, rigidly spongiose- 
herbaceous, dull yellowish green, the inner surface slightly concave and sometimes 
transversely corrugate, the outer surface often longitudinally striate in drying, the 
costa percurrent, evident as a slight dorsal ridge, a little stronger at the base and 
decurrent, the stem thus angled, but not sharply so; margins of the leaves and sporo- 
phyls strongly hyaline, distantly denticulate-serrulate, the teeth mostly low and 
rounded or those of the sporophyls a little more evident, sharper and closer; sporangia 
crowded, orbicular-reniform, 1.5 to 2 mm. broad, extending far beyond the sides of 
the sporophyls.
