 versely ovate, brownish-green, concave; appendages white, orbicular entire: 

 ovary glabrous : carpels very strongly keeled: styles bifid to near the base, 

 thrice the length of the immature ovary and recurved to its base.— A loosely 

 growing shrubby plant. Branches 12-30<^"' long (as collected) ; internodes^3='», 

 leaves 5-12'""' long, 2-,'-)"'n' wide. Common on stony ridges, near La Paz. Near 

 E. coUectioides. No. 43. 

 Euphorbip Xanti Kngelm. Named from a specimen collected by Xantus at Cape 

 San Lucas. A form with variegated (white and rose) appendages and lanceo- 

 late leaves 2-3 <="' long and 3-7 """ wide. Plants 2-3^ '" high, with a number 

 of stems and but few branches, and having flowers white within and rose col- 

 ored without. No. 12. 



Euphorbia Comonduana MiUsp. Proc. Gal, Acad. 2nd series, II. 229. Named 

 from a specimen collected at Comondu, on this peninsula, by Mr. T. S. Braude- 

 gee. A rather compact plant l-l^ '" high, found growing among underbrush 

 upon mesas. Again we regret the absence of frnit upon the specimens collected, 

 rendering the exact place of this species uncertain. No. 63. 



Euphorbia dentata Michx., var. lasiocarpa Boiss. DC. Prodr. XV^. 72. Named

SALICACEiE. 



Mr. M. S. Bebb kindly furnishes us the followiug notes on the only 

 Willow collected : 



Salix bonplandiana II. B. K., var. pallida Anders. Monog. Sal. 18, DC. Prodr. 16'-, 

 20U. Salix nigra Mumb., forma serotina (?) This appears to bear the same rela- 

 tion to more northerly forms of jS. nigra which the serotinous state of S. lasio- 

 lepis, at one time recognized as a good species, does to the normal development 

 of typical Usiohpis. The appearance of the aments in the axils of the mature 

 leaves is the result of climatic influences, and would seem to bo in the former 

 instance, as it is well-known to be in the latter, of no significance, not even 

 as indicating a variety. The leaves are not thinly pubernlons, as they are 

 said to be in the type specimens from Miizattan, but this character is so incou- 

 Btant in forms of this group that its absence only calls for mention because of 

 the undue prominence given it in describing S. pallida Kuuth,
