512 DESCRIPTIONS OF NEW SPECIES 
shrubs on the banks of the Guadaloupe. July, September. — Stems prostrate ; branches weak, ascending, supported 
by the shrubs under “ which the plant grows, often 6-10 feet long ;” —the specimens before me are 2-4 feet long. 
Lower leaves 24-34 inches long, 1-1? wide. Pedicels 6-12 and more lines long, thickened at the apex. Sepals 
about one line long ; flowers pclae 4-5 lines in enn purple. Capsule about one line long, almost [154] 
globose, Seeds smoother than in any other of our species.t 
Sma HETEROCARPA, Lngelm. : stellato-pubescens ; caule erecto ramoso ; foliis basi subcordatis eo [163} 
crenato-dentalis, inferioribus lanceolatis, superioribus linearibus ; tuberculo sub basi petioli subspinoso ; petio 
brevibus ce setaceas a oh cellas solitarias s. Suecioulates superantibus ; carpellis 5 nigris ivanell 
apice pubescentibus latere tenuiter rugulosis, dorso membrana tenui evanescente clausis. — Roadsides, waste places, 
Houston, Texas, with S. spinosa. Annual? Flowers in August and September. Distinguished from S. spinosa by the 
narrower dentate-crenate (not serrate) leaves, and smaller black (not light brown) carpels, rugulose (not lacunose- 
reticulated) on the sides, with a prominent point on the back, broader, shorter, more divaricate not erect beaks. The 
escapes through the back, not through the regular opening at the top. 
359. Vitis candicans, Engelm. (V. estivalis, Michz.) 
1 Besides these two species, we have in the flora of the 
United States three others very different from these, but 
nearly related to one another, namely, t the well-known 7’. 
P-» 
lorum, Nutt.; all three now in cultivation with 
me, and are well distinguished. 7’. cal yeinum is or orna- 
mental ; the large flowers have sometimes six to ten 
PORTULACA, 
Mr. Lindheimer rag cone two undescribed species 
in Western Texas se plants are so difficult to preserve 
and so Tn when dried, he did not collect specimens for 
distribution ; but from his seeds both were raised by me last 
difference from that species. I arrange the species of our 
flora (all of them annuals) in the Sure manner.

ern Texas. Flowers open in direct sunshine between 84 and 
934 a.M. (in St. Louis, in August), always before the common 
species. — Distinguished from the nearly allied P. oleracea 
by the broader retuse leaves, and broader calyx ; by the lar-

cending) the number counted was 15. Stigmata almost

almost naturalized ; originally from Chili. Flowers 20-24 
lines in diameter, open from 8 or 9 to 2 or 3 P. M. in sun-
