campanulato-ampliata, labio inferiore intus villoso-barbato ; antheris 

 filamentisque glabris; filamento sterili subexserto hinc longe parce- 

 que barbato. — N. W. California, on Humboldt Ridge, Humboldt 

 Co., 1878 and 1879, in a spruce forest, V. Rut tan. The upper part 

 of our plant is. in general, not badly represented by the figure of P. 

 campanulatus in Bot. Mag. t. 3884, which seems to be P. perfoliatus, 

 Brongn.. a Mexican species. It is very unlike any other Californian 

 species, and is dedicated to the discoverer, who began his contributions 

 of materials for the flora of that State several years ago, and has now 

 for two summers devoted his vacation to the botanical exploration of 

 its northwestern counties with gratifying success. Mature fruit has 

 not yet been collected ; but partially-formed capsules show forming 

 seeds with an apparently loose cellular coat, investing a small nucleus. 

 Its seeds may, therefore, be not unlike those of an anomalous species 

 of the forests farther north, Chelone nemorosa of Douglas, which Traut- 

 vetter transferred to Peiitstemon, and which in Syn. Fl. N. Am. ranks 

 as a subgenus, Nbthockelone. Its seeds are really not those of Chelone, 

 and the two genera might be better defined by transferring this con- 

 necting section to Pentstemon. But mature seeds of the present spe- 

 cies should first be examined. 



Var. minor is apparently a depauperate state or form of the 

 present species with flowers one half smaller. Collected on Indian 

 Creek, Del Norte County, California. 



Orthocakpcs Bidwelli;k. Triphysaria, facie O.eriantM, Benth.; 

 spica laxiore ; corolla graciliore, fauce cum galea atro purpurea, labio 

 trisaccato laste aureo ; testa seminum laxa arilliformi cellulosa. — Cali- 

 fornia ; near Chico, Mrs. John Bidwell ; near Auburn, Placer Co., 

 Mrs. Pulsifer-Ames. — Within a few weeks after the publication of 

 the first part of the Synoptical Flora of North America, which con- 

 tains this already large genus, we received, almost simultaneously 

 from these two sources, specimens of this well-marked new species. 

 The name of Mrs. Ames is well known in Californian Botany, to 

 which she has made many interesting contributions. Let this neat 

 species commemorate its other discoverer, Mrs. Bidwell, from whom 

 we have received excellent collections, made by General Bidwell and 

 herself upon their own ranche at Chico, and upon the mountains 

 toward the sources of Chico Creek. In foliage this species is hardly 

 distinguishable from 0. erianthus, although somewhat less pubescent ; 

 the filiform tube of the corolla is even more slender, over half an 

 inch long ; and the trisaccate lip is rather smaller, of a bright golden 

 yellow color, while the throat as well as the galea is dark purple.
