CATALOGUE OF SPECIES. 103 



Above timber-line in the Sierra Nevada (Nos. 1749, 2055). This beautiful species 

 hiis beeii described merely as decumbent. It is really cespitose, however, forming 

 close mats often 50 cm. in diameter, and rising only about 5 cm. above the ground. 



Zauschneria oalifornica Presl, Rel. Haenk. ii. 28 (1830). Type locality, "in 



California ad Monte-Key.'' 



Near Fort Tej on (No. 1153). This is a narrow-leafed form, intermediate between 

 fhe type of the species and the variety latifolia. 



Clarkia elegans Lindl. Hot. Keg. xix. t. 1575 (1833)— Dougl. in lilt. Type lo- 

 cality, "in California." 

 In the lower altitudes of the Sierra Nevada (Nos. 1104, 1145). 



Clarkia rhomboidea Dougl. in Hook. Fl. Bor. Amer. i. 214 (1834). Type locality, 

 "from the Great Falls of the Columbia to the Rocky Mountains." 

 Tejon Mountains (No. 1182). 



Clarkia xantiana Gray, Proc. Bost. Soe. Nat. Hist. vii. 140(1839). Type local- 

 ity, in the vicinity of Fort Tejon, California. 



Dr. Gray, in the original description of this species, mentions the fact that 

 "there are no scales at the base of tbe filaments; but the throat of the short funnel- 

 form tube of the calyx is evenly and densely bearded with villous hairs." These 

 hairs closely resemble the hairy scales at the base of the filaments in C. elegans and 

 C. rhomboidea; and the statement in the Botany of California, vol. i, p. 232, that 

 tli£ claw of the petal is short and broad, but not hairy or appeudaged at tbe base, 

 while technically correct, is apt to mislead the reader. The petals often have, be- 

 low the sinus, a dark purple, light-margined spot. The species is a local one, con- 

 fined, so far as known, to the southernmost Sierra Nevada (Nos. 1060, 1151) and the 

 contiguous portions of the Coast Ranges. Both onr stations were in the scant shrub- 

 bery along the lower edge of the chaparral. The soil was a hard, dry clay, sup- 

 porting considerable annual vegetation. The flowers are remarkably delicate and 

 beautiful. 



Gay ophy turn eriospermum sp. nov. 



Plant 30 to 50 cm. high, widely branched; stem glabrous; leaves narrowly linear, 

 acute at apex, attenuate at base, the largest 5 cm. long and 3.5 mm. broad; pedicels 

 5 to 10 mm. long, erect; ovary appressed-pnbesceut ; calyx lobes 4 mm. long, spar- 

 ingly a p pressed- hairy ; petals 5 to 6 mm. long, obovate, rose-colored in age, probably 

 white when first expanded; capsule erect, about 1 cm. long, torulose, commonly 8- 

 to 10-seeded; seed 2 mm. long, narrowly obovate, densely pubescent. 



Type specimen in the United States National Herbarium, No. 1316, Death Valley 

 Expedition; collected July 28, 1891, along the road at Big Tree Canon, on the 

 East Fork of Kaweah River, Tulare County, California, by Frederick V. Coville. 



This plant differs from all the described species except a. lasiospermum in its hairy 

 seeds, and from that in its much larger flowers and the longer, denser pubescence of 

 the seeds. In general appearance it most nearly resembles G. diffusum, 



Gayophytum lasiospermum Greene, Pittonia, ii. 1G4 (1891). Type locality, 

 "near Julian, San Diego Co., California." 

 Near Kernville (No. 1040), and near Fort Tejon (No. 1180). 



Gayophytum ramosissimum Torr. & Gr. Fl. i. 513 (1840). Type locality, 

 " Pocky Mountains, etc." 



Black Canon, White Mountains (No. 1797). Determined by E. L. Greene. 



CEnothera aiyssoides Hook. & Arn. Bot. Beech. 340 (1840-41). Type locality, 

 "Pine Creek, Snake Country," southwestern Wyoming. 

 Near Keeler (No. 859).
