BOTANY.

* San Francisco Spring, Sonora ; Parry, The seeds were not ripe. This is, perhaps, a distinct 



species, but it must remain as a variety until more complete specimens are obtained. 



EupnoRBiA LathyriS; Linn, is somewhat naturalized around Monterey, California. It was 

 doubtless introduced by the Spaniards, We have it also from Saltillo, Mexico, where it was 



collected by Gregg. 



Y. SPARSIFLORJE. 



EupuoRBTA MISERA, BenOi, Bot. SulpJi, p. 51. Near the sea, San Diego, California; Parry. 

 A straggling bush, about 3 feet high, abounding in a milky juice. Nuttall found it at Santa 

 Barbara. 



Euphorbia antisyphiliticA; Zticc. Acad. 3Ion. lyp. 292. Rocky and gravelly hills along the 

 Bio Grande, from the Presidio del Norte to Laredo ; Bigelow^ Schott. Eemarkable for its long 

 terete nearly leafless branches, which resemble an Equisetura or an Ephedra. 



Phyllanthus CarolestianuSj Walt. FL Car. p. 228 j Ell. Sp. 2, p, 661. P. obovatus, Willd. 

 Sp. 4, p. 574. Maschalanthus obovatus, Nutt. Trans. Amer. Phil. Soc, (n. ser,) p. 1Y5.

PiiYLLAi^THus P0LYGON0IDE3, NuH. I. c. P. Rocmerianus, Scheele in Linna^a^ 25, p, 583. Dry, 

 sandy, and rocky places along the Rio Grande, from New Mexico to the Gulf, and westward in 

 the Mexican States. (No. 1819, Wright ; No. SST, Coll. II, DrummondS) This is certainly an 

 annual, but late in the season, when the lower part of the stem and the root have become indu- 

 rated and ligneous, it appears as if suflfruticose. 



Phyllanthus ericoides (n. sp.) : fruticulosus, ramosissimus ; foliis oblongo-lanceolatis imbri- 



cato-confertis subsessilibus glabris coriaceis mucronatis ; floribus dioicis axillaribus solitariis 



brevi-pedicellatis ; calycibus 5-(raro 6-) partitis. High mountains near the Rio Grande, in 



[ Chihuahua, October ; Parry, Plant about a span bigh. Leaves about 2 lines long and scarcely 



more than balf a line wide^ acute, nearly sessile, with a pair of subulate persistent stipules at 

 the base. Male fl.owers about a line long. Calyx deeply 5-parted ; the segments oblong and 

 somewhat obtuse. Petals none. Stamens 3 ; the filaments united into a column^ at the base of 

 which are 5 roundish glands. Female flowers rather larger than the male ; the segments oblong, 

 acute. Petals none. Ovary with 5 glands at the base; cells uniovulate. Styles 3, two-cleft; 

 stigmas sub-globose. A well characterized species, remarkable for its very small crowded leaves. 



Lepidanthus phyllanthoides, Nittt. I. c. Eavines on the San Pedro river, western Texas ; 

 BigelotVj Schott. (No. 636, Wright.) Mr. NuttalPs description of this very distinct genus can 



hardly be improved, 



Croton Berlandieri (n. sp.) : suflfruticosum ; ramulis inferne nudis ; foliis ovatis cordatis. 

 acuminatis membranaceis utrinque stellato-pubescentibus integerrimis vel obsolete denticulatis 

 basi efflandulosis; floribus monoicis, masculis breviter racemosis 5-petalis 20-30-andris, foemineis~ 



petaliferis ; stylis bis bifidis ; fructibus tomentosis demum glabratis. Neuvo Leon^ December ; 

 Thurbei\ (Nos. 708 and 2125, Berlandier,) Plant apparently about a foot high. Leaves 1-2 

 inches long, I-IA inch wide; the petiole more tban half the length of the lamina, Kacemes 



terminating the branches, pedunculate, Male flowers 10-15, crowded on pedicels about a line 

 long. Petals oblong. Stamens with 5 roundish glands at the base. Female flowers 1-2 at
