52 PITTONIA. 
G. Hormrana. Commonly 1} feet high and loosely panic- 
ulate from near the base: leaves about an inch long and 
spreading, very narrowly linear, acute, only very minutely 
roughened: pedicels filiform, about an inch long: calyx- 
teeth very short: corolla deep rose-purple, ? inch broad and 
nearly as long, the lobes all spreading, broader than long, 
truncate or retuse, villous-ciliate: the longer filaments very 
villous, as also the throat of the corolla behind them ; an- 
thers with prominent incurved mucro. i 
Plentiful in open pine and oak groves along Michigan 
Avenue south of the Soldiers Home grounds near Brook- 
land, D. C., colleeted by Mr. Holm and the writer, 20 Oct., 
1898. Possibly heretofore confused with G. tenuifolia, from 
which it differs very strikingly in that all its corolla-lobes 
are spreading and subequal. In G. tenuifolia (which is a 
much smaller plant) in all its forms, the two upper lobes of 
the corolla are erect,and galeately arched over the stamens, 
while the others are larger and spreading. This excellent 
species I dedicate to my friend Mr. Theodor Holm of Brook- 
land, D. C., not merely out of compliment; for the detection 
of the characters of both these species as distinct and prob- 
ably new, was the result of his own study of them in the 
field; and the excellent plates accompanying this paper are 
from his drawings.
