112 Evans: TAXILEJEUNEA PTEROGONIA 
Cipacon, two stations in the vicinity of Bogota, Colombia, the 
collector in both instances being A. Lindig.* Here, for the first 
time, a monoicous inflorescence is ascribed to the species. 
Next in order is the full and careful account by Spruce in his 
‘“Hepaticae of the Amazon and of the Andes,” which appeared 
in 1884. He emphasizes particularly the cordate or auriculate 
features of the leaves and underleaves, describing the auricles of 
the leaves as ‘“‘rotundo-circinata,” and those of the underleaves as 
“‘forficato-imbricata.”’ He alludes, moreover, to the small leaves 
and underleaves of the female branches and states that each 
innovation bears ‘‘only a single row of them below the flower.” 
He describes the leaves as “pauciserrulata’’ (with about four 
teeth) in the vicinity of the apex, and implies that the lobule is 
always very minute. With regard to the bracts he makes no 
mention of the lobule but states that the lobe varies from oblong 
to ovate-lanceolate, the upper portion being more or less serrate. 
The perianth he describes as five-angled in the upper part with 
winged angles, the wings being extended as “‘laciniato- ciliatove- 
cristata” horns. Spruce cites the species from the Pastasa River, 
Ecuador, R. Spruce; from’ Mount Campana, Peru, R. Spruce; 
and from Caldas, Brazil, G. A. Lindberg. He notes also its earlier 
collection in Peru and Mexico, apparently ignoring Gottsche’s 
statements regarding the Mexican specimens. 
It will be seen that definite and well-authenticated records for 
T. pterogonia up to this time are restricted to scarcely half a dozen 
localities in South America. The researches of Stephani, however, 
brought a few additions to the list. In his revision of the “Gat- 
tung Lejewnea im Herbarium Lindenberg.” published in 1890, 
he quotes the species from Peru (the original Kunze specimens) 
and also from the following stations: Mirador, Mexico, Liebmann 
262, 326; Merida and Tovar, Venezuela, Moritz.t The Mexican 
specimens represent Omphalanthus subalatus, which, in Stephani’s 
opinion, is a form of O. pterogonius with entire leaves. He thus 
differs from Gottsche who found the differential characters in 
the perianths. Some of the Venezuela specimens are listed in 
the Synopsis under the name O. debilis y* columbicus; the others
