398 PROCEEDINGS OF THE AMERICAN ACADEMY 



421. Gilia (Navarretia) intertexta Steud. ; Gray, 1. c. 



422. Gilia capitata Dougl. ; Hook. Bot. Mag. t. 2698. 



423. Nicotiana multivalvis Lindl. Bot. Reg. t. 1057. 



424. Erythr^ea Nuttallii S. Watson, Bot. King, Expl. p. 277, 

 t. 29. I presume that this is also Cicendia exaltata Griseb. in Hook. 

 Fl. Bor.-Am. 2, p. 69, t. 157, and that the characters "stylo nullo" 

 and " stigmate vix distinguendo " were based in some way upon the 

 imperfection of the specimen, — the style perhaps broken off. The 

 anthers are linear-oblong, and as much twisted when dry as in several 

 other species of Erythrcea. The stigma is actually that of Grisebach's 

 section Euerythrcea, in these specimens much more divided than in 

 Watson's figure. 425. Var. tenella. A smaller form, one to three 

 inches high. 



426. Gentiana affinis Griseb. in Hook. 1. c. p. 56. 



427. Apoctnum andros^emifolium L. : the Western form. 



428. Asclepias speciosa Torr. Ann. Lye. N. Y. A. Douglasii 

 Hook. Fl. Bor.-Am. 2, p. 33, t. 142. 



429. Asclepias fascicularis Decaisne in DC. Prodr. 8, p. 569. 



430. Fraxinus Oregana Nutt. Sylv. 3, p. 59, t. 99. 



431. Asarum caudatum Lindl. Bot. Reg. sub 1. 1399. A. Hookeri 

 Fielding & Gardn. Sert. t. 32. 



432. Atriplex littoralis L. : narrow-leaved variety, in few 

 specimens. 



433. Atriplex (Obione) truncata. Obione truncata Torr. in 

 Watson, Bot. King, Expl. p. 291. Two or three specimens of the 

 typical plant : those distributed are — Var. stricta : foliis hastato- 

 lanceolatis nunquam cordatis, inferioribus basi cuneatis ; inflorescentia 

 virgata minus foliata. A. patula var. foliis magis argento-furfuraceis 

 Hook. Fl. Bor.-Am. 2, p. 128, ex char. The fruit (indurated theca), 

 as in the Nevadan specimens, is 3 - 4-toothed at the truncate summit, 

 the teeth variable, middle one rarely a little produced, and some tuber- 

 cles occasionally developed on the disk. 



434. Amarantds retroflexus L. var. A. occidentalis Nutt. 

 herb. ; a depauperate and smooth form. 



435. Eriogonum compositum Dougl. in Benth. Eriog. t. 17;
