walls of limerock, Iguala Cafion, near Iguala, Guerrero, Mexico, 28 
December, 1906, C. G. Pringle, no. 10,367 (type, in hb. Gray), A 
species peculiar in its terete canescent-tomentose stem. 
Stemodia macrantha Robinson, n. sp., suffrutescens 1 m. vel ultra 
alta ; caulibus decumbentibus gracilibus teretibus pubescentibus ; ramis 
saepius simplicibus erectis vel ascendentibus viridibus patenter pilosis 
6 dm. longis, internodiis 3-10 cm. longis; foliis lanceolato-ovatis 
pian angustatis 5-6 cm. longis 2.5-3 em. latis basi cuneata excepta 
crenato-serratis supra atroviridibus adpresse pilosis subtus paulo palli- 
dioribus in costis et venis lateralibus pinnatis hirsutulis ; petiolis 1 cm. 
longis hirsutulis superne alatis ; inflorescentia terminali 1-4 dm. longa 
perlaxa folioso-bracteata, pedicellis filiformibus flexuosis glanduloso- 
pubescentibus unifloris 2-4 cm. longis ascendentibus ex axillis brac- 
tearum saepissime ternis vel quaternis orientibus; calycis laciniis 
glanduloso-pulverulis et hispidulis lanceolato-linearibus superioribus 
anthesi usque ad 7 mm. longis infimis paulo brevioribus omnibus a 
basi gradatim angustatis sed apice vero obtusiusculis; corolla 1.8-2 
em. longis, tubo viridi-flavescenti cylindrato ca. 13 mm. longo 4 mm. 
diametro purpureo-nervio intus externeque piloso ad fauces distincte 
sursum curvato, limbo laete purpureo, lobis suborbicularibus subae- 
qualibus apice saepissime retusis ; staminibus brevioribus mediae parti 
tubi affixis 3 mm. longis longioribus paulo supra basin tubi affixis 
8 mm. longis omnibus inclusis antheriferis glabris ; capsula ovoidea 
5 mm. longa atrobrunnea a calyce persistenti circumdata. — Shaded 
bluffs of the deep barranca, near the foot of the Falls of Tzardracua, 
below Uruapan, Michoacan, Mexico, 28 January, 1907, C. G. Pringle, 
no. 10,356 (type, in hb. Gray). This species is amply distinguished 
from its Mexican congeners by its much larger flowers, which in fact 
are decidedly showy for the genus. 
Losetia Netsonm Fernald, var. fragilis Robinson & Fernald, n. var. 
a forma typica recedit foliis utrinque viridibus juventate sparse pilo- 
sulis mox omnino glabratis lineari-lanceolatis multo brevioribus, maxi- 
mis ca. 7 cm. longis 8-10 mm. tantum latis. — Mexico, C. G. Pringle, 
no. 10,360 (type, in hb. Gray). This variety shares with the typical 
form the sof woody stems and branches as well as all the more impor- 
tant characteristics of the inflorescence. The varietal name is suggested 
by the extreme brittleness of the branches, at least when dried. The 
variety, like the typical form, has numerous showy flowers with bright 
scarlet corolla. Both plants seem worthy of cultivation.
