102 BOTANY OF THE DEATTT VALLEY EXPEDITION. 



Callitriche palustris L. Sp. PL ii. 0(»9 (1753). Typo locality European. 

 Near Whitney Meadows (No. 1641). 



LYTHRACEJB. 



Ammania coccinea Rottb. PI. Hort. Univ. 7 (1773). 



Near Visalia (No. 1272). The true A. lati folia of LiunseuB is now considered to be 

 the more southern plant, without petals, but otherwise very closely resembling our 

 northern species. 



Ammania ramosior L. Sp. PL i. 120 (1753). Type locality, "in Virginia." 

 Near Visalia (No. 1252). This is the Ammania hitmilis of the Botany of California. 



Ly thrum album H. B. K. Nov. Gen. & Sp. vi. 193 (1823). Type locality, "prope 

 Salamaucam Mexieanorum, alt. 900 hex." 



This plant has passed under the names L. ealifonticum Torr. &. Or. and L. alatum 

 linear if olivm Gray, but both have been referred to L. album by Koehne. 



The species was observed at the Eagle Borax Works, Death Valley; in Furnace 

 Creek Canon; in the south end of Keating Springs Valley; at Winters'a ranch, 

 Pahrump Valley; at Ash Meadows; and in Surprise Canon, Panamint Mountains. 

 The plant is characteristic of permanently wet, boggy soil, growing usually among 

 grasses and sedges. 



ONAGRACE3!. 



Epilobium adenocaulon occidentale Trelease, Rev. Epilob. 95 (1891). Type 

 locality, " Vancouver Island and British Columbia to central California, and Nevada." 

 Near Mammoth, Mono County (No. 1823). 



Epilobium anagallidifolium Lam. Encycl. ii. 376 (1786). Type locality, "Mont 

 d'Or," France. 



Whitney Meadows (No. 1617). The capsules in our specimens reach 45 mm. in 

 length. 



Epilobium augustifolium L. Sp. PL i. 347 (1753). Type locality European. 



Valley of the Kaweah River (No. 1367). The American forms of this species are 

 said not to be the same as the type of Linnaeus, and for this reason Lamarck's name, 

 E, spicatum, has been adopted by several writers. There seems no possibility, how- 

 ever, that this group of plants includes two species; but it may be found necessary 

 to use a varietal name for our plant. 1 



Epilobium brevistylum Barbey, Bot. CaL i. 220 (1876). Type locality, "Sierra 

 County," California. 



Near Mineral King, Sierra Nevada (No. 1139). 



Epilobium glaberrimum Barbey, Bot. Cal. i. 220 (1876). Type locality, ''in the 

 Sierra Nevada; Vosemite Valley ; Sierra Valley." 



At low altitudes in the Sierra Nevada (Nos. 1209, 1331, 1773). 



Epilobium holosericeum Trelease, Rev. Epilob. 91 (1891). Typo locality, "Cali- 

 fornia: San Bernardino county and Kern county." 

 Near Bakersfield (Nos. 1245, 1246). Determined by William Trelease. 



Epilobium obcordatum Gray, Proc. Amor. Acad. vi. 532 (1865). Type locality, 

 "in the Sierra Nevada, at Squaw Valley and Ebbett's Passes, alt. 8,000-8.500 feet." 

 The latter locality, and probably the first also, is in Alpine County, California. 



1 The retention of E, augustifolium is advocated by Edward S. Marshall in the British 

 Journal of Botany, vol.xxix, p. 309 (1891J.
