418 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. 
and the smaller distal portion reduced to a few tortuous, spreading, filaments which 
resemble flaccid paraphyses. The divisions of the indusia appear like a lax scaly 
covering to fertile portions of the leaf, but sterile segments will be found nearly or 
quite devoid of scales. 
Besides a portion of the type received from Berlin, the following specimens are in the 
U.S. National Herbarium:

7. Hemitelia escuquensis Karst. Fl. Columb. 2: 181. 1869. 
Type Locatrry: Humid mountains near Escuque, western Venezuela, upon the 
southern shores of Maracaibo Harbor, altitude 100 meters. 
DistripuTION: Known also from Porto Rico. 
ILLUSTRATION: Karst. op. cit. 2: pl. 196. 
Hemitelia escuquensis was described and elaborately illustrated by Karsten from 
specimens collected by Engel in a district now included in western Venezuela, Aside 
from this collection the species is apparently known only from Porto Rico, two num- 
bers (4102 and 6156) of Sintenis’ specimens from that island being cited by Urban.! 
Of these only 4102 is found in the U.S. National Herbarium, this being represented 
by two specimens, one of which is unmistakably Cyathea portoricensis Spreng. and the 
other a partially fertile condition of a Hemitelia which, in the writer’s opinion, is not 
specifically different from J/. escuguensis. This opinion is based upon a comparison 
of the latter with a pinnule of Engel’s original specimen, received from Berlin through 
the courtesy of Dr. Georg Hieronymus. Upon the authority of Doctor Hieronymus, 
however, the Berlin specimens of nos. 4102 and 6156 represent a single species which 
(both of the specimens being sterile) can not be referred definitely to the genus 
Hemitelia. They are said by him to be certainly distinct irom /. eseuquensis and it 
is probable that both appertain to Cyathea portoricensis. 
The Hemitelia element of no. 4102 in the U.S. National Herbariuin agrees closely 
in the more essential minute characters with the type fragment of H. eseuquensis and 
with the detailed description by Karsten. It differs mainly in the lesser size of nearly 
all of its parts and in having the segments less strongly lobed. It has the following 
data:
