otherwise tripinnate nearly throughout; primary and secondary rachises stout, terete, 
marginate only at their extreme apices; basal primary pinne deltoid, 75 cm. long, 
60 cm. broad at the strongly equilateral base, the inferior basal secondary pinna 40 cm. 
long and 25 cm. broad (the proximal portion strongly produced), the superior basal 
secondary pinna 20 cm. long and 9 cm, broad, the other secondary pinnz more nearly 
equal, essentially so near the abruptly acuminate apex, the tertiary rachises alate 
only toward the apices; second pair of primary pinnie less basiscopic, deltoid, 55 cm. 
long, 30 cm. broad; third and fourth pairs nearly equilateral, respectively, 30 and 
40 cm. long, 23 and 17 cm. broad, the succeeding pinnie (about 3 pairs) successively 
shorter and finally simply pinnate below the abruptly short-acuminate apex of the 
lamina; larger pinnules (third order) of the basal part of the frond 10 to 17 em. long, 
2.5 to 7 cm. broad, oblong, acuminate, pinnate (the rachises widely alate), the 
quaternary segments mostly oval to oblong (1 to 1.5 cm. long), rounded or obtuse, 
lightly crenate, with 5 to 7 pairs of simple or once forked dark veins, or a few of the 
largest ones longer (3 to 4.5 cm, long), deeply lobed, with 7 to 10 pairs of veins, each of 
these with several alternate branches within the lobes. Under suriaces of the secondary 
and tertiary rachises bearing a few thin flaccid light brown scales; ultimate rachises 
and veins bearing a few whitish spine-like trichomes upon the upper surface; lea! 
tissue naked upon both surfaces, dark green, slightly lighter beneoth. 
Type in the U. S. National Herbarium,. nos. 676198-203, consisting of a single frond, 
collected in humid forest near the upper Caldera River, at “Camp I,’’ Holcomb’s trail, 
above El Boquete, Chiriqui, Panama, altitude 1,625 meters, March 24, 1911, by 
William R. Maxon (no. 5704). 
Only a single plant of this species was observed during three days’ collecting in the 
general region of ‘Camp I”’ and this, unfortunately, had but one frond, The charac- 
ters afforded by this individual, however, even in a sterile condition, are sufficiently 
marked to warrant its description as a new species. In the remarkable basiscopic 
development of the basal pinnz, as well as in the widely alate tertiary rachises and 
the peculiar spine-like trichomes of the upper leaf surface, Marattia pittieri shows an 
undoubted affinity with M. kaulfussii, so that there can be scarcely any question as 
to its proper reference to the subgenus Eupodium. From M. kaulfussti it differs 
greatly in its enormous size and in its much larger and differently shaped segments. 
which for the most part are lightly crenate, only the very largest ones in the most 
dissected part of the basal pinnie being lobed. 
Named in honor of Mr. Henry Pittier, with whom the writer was associated in 
botanical exploration during the Smithsonian Biological Survey of the Panama Canal 
Zone and adjacent territory. 
NOTES ON LYCOPODIUM. 
The following notes are in continuation of earlier studies of tropical 
American species of Lycopodium, published either separately or as 
parts of longer papers, and relate mainly to species previously 
described. There are included, also, descriptions of two new species, 
and the publication of the new name Lycopodium blepharodes, applied 
to a South American plant described originally under an invalid 
name. 
Lycopodium dichotomum Jacq. Enum. Stirp. Vind. 314. 1762. 
The original description of this species in 1762, though brief, is sufficiently complete 
to fix its application to the plant so elaborately figured by the same writer a few years 
later.’ The type is from Martinique, and the species is not uncommon in the West 
Indies and continental North America, excellent specimens being at hand from 
‘Hort. Bot. Vind. 3: p/. 45. 1776.
