respect to our Californian species. I may add, that in re- 

 spect to color, B, volubilis is commonly rose or nearly white, 

 but not rarely exhibits the violet shade which predominates 

 in the genus. Its flowering season is from early in May to 

 the middle of June. 



B. MULTIFLORA, Bentli. Scape 2 — 4 feet high, scabrous, 

 under the umbel, tortuous or occasionally twining as in the 

 last: perianth deep violet-purple, 8 — 10 lines; tube narrowly 

 constricted above, twice as long as broad, shorter than the 

 spreading segments: staminodia obtuse, entire, little ex" 

 ceeding the oblong, deeply bifid anthers. — PI. Hartw. 339;

From central California to Oregon, in the mountains onlyr 

 at least in California. Mr. Watson's remark in the second 

 volume of the Botany of California, that the present species 

 flowers a month or two earlier than B. congesta, evinces en- 

 tire lack of knowledge on the part of his informants. B. 

 multifiora is the latest of all species, being found in good 

 condition of flower as. late as July. It is considerably later 

 than B. congesta, which is next to it in tardiness. 



B. CONGESTA, Smith. Scape 3 — 5 feet high, flexuous, but 

 apparently never twining: flowers blue-purple, in a dense 

 capitate raceme: perianth as in the last species: staminodia 

 bifid, spreading with the limb of the perianth, and purple, 

 as in no other species. Trans. Linn. Soc. x. 3. t. 1; Baker,

Central California to the borders of British Columbia, in 

 open or wooded places among the foothills, flowering in May 

 and June. The figure in the Transactions of the Linnean 

 Society was apparently taken from a specimen not well de- 

 veloped, and does not indicate that distinctly racemose char- 

 acter of the inflorescence which Mr. Watson supposes to be
