REVISION OF EPILOBIUM. 97 
Haussknecht ; San Diego county, Palmer, 1875, 94 in part 
and 142; Santa Cruz Island, G'reene, 1886). — Apparently 
this species, but with more appressed pubescence, in the 
Santa Rita Mountains of Arizona (Pringle, July 8, 
1881.).— Plate 26. 
Somewhat intermediate between what I have placed un- 
der adenocaulon as var. ( ?) perplexans, and the next species. 
21. E. Parisum, Trelease.—Tall, at length stout and 
rather intricately branched even from the base, glabrous be- 
low, the inflorescence and capsules very sparingly, the young 
buds densely white tomentose; leaves 25 to 75 mm. long, 
lanceolate, very obtuse or the reduced uppermost leaves 
acutish, somewhat unequally serrulate or denticulate, 
gradually or abruptly narrowed to slender more or less 
elongated winged petioles, rather thin and glabrous ; flowers 
at length numerous, suberect, rosy; fruiting peduncles 
about 15 mm. long; seeds short beaked, .4x1 to 1.25 
mm.; coma white.— Zoe, i. (1890), 210. — San Bernardino 
county, California (Parish, Nov. 1889, nos. 2094 and 
2095, the former apparently summer seedlings or offsets 
- from the latter); and near Todos Santos, Lower Cali- 
fornia ( Brandegee, Jan. 22, 1890), — unless this, with more 
closely crisp flower buds, should prove to be #. Mexi- 
eanum. — Plate 27. 
++ Habit and general characters of the preceding group, but innova- 
tions in the form of very short rhizomes ending in open fleshy-leaved 
turions below ground or developing into rosettes or tufts of thin leaves 
when they emerge: leaves not revolute, 
22. E. pornate, Hausskn.— Becoming large and consid- 
erably branched, glabrate below, very crisp-pubescent above 
even as to the young leaves and flower buds ; leaves 50 to 75 
mm. long, ovate to lanceolate, gradually very acute, 
coarsely denticulate to almost serrate, the upper rather 
gradually narrowed to evident petioles, thin ; flowers finally 
abundant, erect, rosy, 5 mm. long; capsules at length 
glabrate, their crisp-pubescent peduncles scarcely 5 mm.
