Nemacladus rubescens. 



Glabrous, like the preceding, and very similar in foliage 

 and habit: pedicels divaricate or somewhat ascending: calyx- 

 teeth twice as long as the very short tube which is adnate 

 to the base only, of the globose, 20 — 40-seeded capsule: co- 

 rolla apparently open-campanulate, without tube, from light 

 rose-color to dark rose-red: stamineal tube elongated, equal- 

 ing the calyx in length : seed oblong, with undulating striae. 



Eeno, Nevada, and Mohave Desert; Mrs. Curran, 1884. 

 Most of the Calif ornian " N. ramosissim/us" of earlier col- 

 lectors appears to belong here ; but the greatly elongated 

 stamineal tube and the beautifully undulate-striate seeds will 

 at once distinguish it from that species. 



Nemacladus montanus. 



Radical leaves spatulate-oblong, entire; whole plant glab- 

 rous, or with some villous hairs on the inner portion of the 

 base of the 'pedicels and on the stem opposite: pedicels 

 firmly ascending: calyx-teeth lanceolate, subequal and equal- 

 ing the turbinate tube, which is adnate to the lower half of 

 the 7 — 12-seeded capsule: corolla rather large, white, open- 

 campanulate: stamineal tube elongated: seed large, ovate- 

 oblong, with longitudinally compressed, zigzag reticulation. 



Mountain districts of the central portions of the State: 

 Butte County, Elisha Brooks; Lake County, D. Cleveland; 

 Yo Semite Valley, Mrs. Curran. In respect to the paucity 

 of the seeds, the species is like N. capillaris, but the reticu- 

 lation of them is widely different. 



Nemacladus pinnatifidus. 



Glabrous throughout: radical leaves linear-lanceolate, 

 once or twice pinnatifid, the cauline coarsely toothed: pedi- 

 cels divaricate, abruptly bent upwards beneath the calyx : 

 calyx-tube short-turbinate, the lanceolate teeth surpassed 

 by the rather acute 15 — 25-seeded, oval capsule: seed short- 

 oblong, flattened at each end, with longitudinally com- 

 pressed, favose reticulation.
