CONTRIBUTIONS TO W^ESTERN BOTANY NO. U 143 



In Brandegee's Phynanfhus pemnsularis Erythea 7 B 18S9, got 

 Anthony as his No. 364, wc have specimens of the type labded in Br 

 degee's handwriting, there appear to be two species under this name

the type. Standley refers P. peninsularis to P. Galeottianus. 

 the type is manifestly P, Galeottianus, but most of Brandegee'si descrip- 

 tion is taken from the rest of the material and seems to be a distinct 

 species and shquld stand. The chief c]iaracters are in flie oblong-ovate 

 leaves, sharply acute and widest below the middle, in the pwds being 

 subtended by 5-6 nearly orbicular and green and thick and leaf-like calyx 

 lobes about 4 mm. long, appearing as if a whorl of leaves, and in the 

 sharply triquetrous seeds having flat faces with irregular worm 

 ridges. This is my No. 24489, got at the first ranch out of Todos Santos, 

 on the road to La Paz, and just opposite the house at the south. P. Gale- 

 ottianus is my No. 24485, got on the slopes of the Laguna mountains, 

 March 2, 1928. Both species grow about a yard high, fomnng inconspicu- 

 ous bushes. - 



Euphorbia eriantha Bth. The plants referred to this .species by 

 Brandegee dp not accord with the description in Bot. Sulph. 51 in several 

 particulars, but Brandegee collected the species in the type locality in fine 

 condition, and his specimens correspond well with my own from Todo? 

 Santos. The plant is a woody rooted perennial, a foot to a foot and a 

 half high, from a thick base. The leaves are 2-3 inches long, and mortly 

 2 mm. wide and entire and acuminate or triangular-acute, flat, and with 

 scarcely a petiole, the floral ones inclined to be a little thickened nt b^s^ 

 and pinkish. There are many floral ones in a whorl which form the con- 

 spicuous part of the plant, there are a fe^v stem leaves lower dowTi but 

 inconspicuous. The flowers are about 3 mm. long and hardly reach the 

 basfe of the fruit at maturity. The appendages hardly 1 mm. lon^ and 

 rather rudimentary, the whole flower Jioary with rather dense ard v.-n 

 short hairs. The pods are exserted a trifle from the flo\\er on a st^p^^ 

 and are 6 mm. long by 3 mm. wide, nearly round 

 3_^alcat^ blunt, oblong, ashy with closely appressed and very .short hnim.

 The hilum is excavated a little and with the caruncle raised on a fjicrt 

 pinnacle, and flat and cellular, and round-reniform in outline and about 

 1 mm. wide, and is easilv broken off. This is my No. 24107 from Todo^
