Only two small bushes seen iu a shady place below Sylvan Lake, altitude 1,900 in., 

 July 18 (No. 687). 



Ribes lacustre (Pers.) Poir. Encycl. Supiil. ii, 8.56 (1811); Rihcs oxi/cavthoides 

 lacnsirc Pers. Syn. i, 252 (1805). 



In shady, damp places; not common: South of Lead City, altitude 1,500m., July 

 6; Sylvan Lake, altitude 1,900 m.. August 17, (No. 688). 



Ribes cereum Dougl. Trans. Hort. See. Lend, vii, 512 (1830). 



In Coulter's Manual and in the Botany of California this species has been placed 

 in the wrong section, as the calyx is tubular and the foliage glandular. In the 

 Botany of California the form of the calyx is given in the description of the species, 

 but in Coulter's Manual this is oraraitted. Specimons collected in flower, therefore, 

 have been named E. fiaiigiiineum varieyatum. 



Common : Custer, altitude 1,700 to 1,800, June 11 ; 15 miles oast of tlie same place, 

 altitude 1,400 m., July 23 (No. 689). 



Ribes aureum Pursh, Fl. i, 164 (1814). 



In the foothills: Hot Springs, altitude 1,100 m., .Tune 11 and August 3; Fall River 

 Falls, altitude 1,000 m., June 17 (No. 690). 



CRASSULACEiE. 



Sedum stenopetalum Pursh, Fl. i, 324 (1814). 



It is nearly always more or less branched from the root. On rocky hills: Pied- 

 mont, altitude 1,100 m., June 27; Lead City, altitude 1,700 m., July 6; Buckhorn 

 Mountain, near Custer, altitude 1,800 m., July 18 (No. 691). 



HALORAGIDACEiE. 



Callitriche palustris L. Sp. PI. ii, 969 (1753). 



I mistook this for FJaiine americana, which the plant very much resembles. Com- 

 mon in springs and brooks ; spring, near Buckhorn Mountain, altitude 1,700 m., July 

 15; brook, 6 miles northwest of Custer, July 25 (No. 571). 



ONAGRACEiE. 



Epilobium angustifolium L. Sp. PI. i, 347 (1753). 



Woody hills: Itochford, altitude 1,700 m., July 11; Sips Spring, in the Limestone 

 District, altitude 1,800 m., July 28 (No. 692). 



Epilobium Uneare Muhl. Cat. 39 (1813). 



The leaves are often opposite and are acutish, short-petioled, and without veins. 

 In a marsh near Priugle, altitude 1,500 m., August 6 (No. 693). 



Epilobium palustre L. Sp. PI. i, 348 (1750). 



This was named thus doubtfully by Dr. William Trelease. In his letter respecting 

 the 8]tecimens submitted he adds: "However, they are pretty clearly that species, 

 or possibly a hybrid of Uneare, with the leaves broadened by hy bridity." The latter 

 seems to be the case. They are, very likely, hybrids of the preceding and E. adeno- 

 eaiilon, together with which two they were growing. After a careful search in the 

 marsh, I could not find more than four specimens, nor did I see it elsewhere in 

 the Hills. Priugle, altitude 1,.500 m., August 6 (No. 694). 



Epilobium adenocaulon Ilaussk. Oest. Bot. Zeitsch. 110 (1879). 



Two forms wi-rt-. collected. One is branched, with smalhu', more dentate leaves, 

 approaching E. coloratiim in general habit. Priugle, altitiule l,5l>0 m., August 6 

 (No. 695). 



The other is simple, with larger oliloug-ovale leaves Hochford, altitude 1,()00 ra., 

 July 11 ; Custer, altitude 1,600 m., July 14; Hot Springs, altitude 1,050 m., August 8 

 (No. 696).
