96 Nelson — JVeu^ Plants from Nevada. 



puberulent with some longer scattered hairs; leaves pinnatifid or those 

 above nearly entire, oblong in outline, petioled, with short matted pu- 

 bescence and some longer scattered white hairs; inflorescence of nearly 

 straight, slightly divergent secund spikes, softly hispid, and giving the 

 whole plant the appearance of certain Asperifolm; sepals similar, linear- 

 oblong, in fruit 5-7 mm. long, hispid-ciliate; corolla campanulate, bare- 

 ly as long as the sejials, its rounded lobes shorter than its tube, color in 

 doubt, appendages narrow, somewhat united at the base of the filament: 

 stamens well exserted, the filaments sparsely long-bearded on the ex- 

 serted portion; the very slender style cleft to the middle; capsule ovate, 

 pointed, somewhat compressed, included; seed solitary (only one matur- 

 ing), conical-oblong, brown, beautifully retriculate-pitted, 2-3 mm. 

 long, slightly carinate ventrally. 



In its solitary seed it resembles P. platyloba Gray, which is a some- 

 Avhat viscid heterosepalous annual; in its pubescence and some other 

 characters P. liupida Gray which is a diffusely branched annual. 



The type was collected by Prof. F. H. Hillman, June 30, 1893, on 

 Alum Creek in the Sierra foothills. 



Mertensla nevadensis sp. nov. 



Perfectly glabrous throughout; roots large and ragged, the croAvn 

 clothed with the brown dead bases of the leafstalks of*former years; 

 stems 1-2 dm. high, slender, simple; crown leaves numerous, large for 

 the plant, oblong, obtuse or subacute, 6-8 cm. long, 1-2 cm. broad, on 

 slender petioles nearly as long as the blade; stem leaves smaller, becom- 

 ing sessile and lanceolate above; inflorescence terminal, crowded; the 

 short pedicels slender; calyx about 4 mm. long, its entire lanceolate 

 segments about 3 mm. long; corolla tubular, its limb but slightly di- 

 lated, about 15 mm. long (tube 9 mm.; throat 4 mm.; the obtuse rounded 

 lobes only 2 mm.); stamens equal, inserted on the margin of the throat: 

 the filaments broader than the anthers and about as long; throat-crests 

 conspicuous, tipped with brown, broad and noticeably saccate; corolla 

 tube glabrous within but at the base a ring of 10 very minute paired 

 nectariferous pits, one pair on each of the 10 principal nerves of the 

 tube: stjde about equalling the stamens. 



The only species that this seems comparable with is M. oUonrjifolia 

 Don. but to this it only bears some resemblance in its floral characters. 

 It differs from that species in its large elongated root; its larger (not 

 succulent) leaves; its fewer-flowered more open inflorescence. 



Type collected by Messrs. Kennedy and True (No. 711) who report it 

 as common in Hunter Creek Canyon, near Reno, Nevada, May 16, 1903.
