sinuato-pinuatifida, omnia basi cuneato-attenuata : corolla plano- 

 rotata, violacea : antheriE luteoe ovali-oblongae : semina parum 

 numerosa majuscula, dorso crassiore subtuberculato-rugosa. Planta 

 juvenilis atomis papillisve albidis quasi furfuraceis conspersa, casterum 

 glabra.

 at least as to var. subintegrifolium. I have not the Eerlandierian 

 numbers cited under the typical form, but there is no reason to doubt 

 the species. The corolla probably is never yellow in the living plant. 

 The seeds are not very ^Qvf, as Torrey at first supposed, but are pretty 

 large. The aspect of this small and low species is peculiar and much 

 like that of Chamcesaracha ; but the fruiting calyx is that of a true 

 Physalis. The papillose scurf, in place of pubescence, is peculiar, but 

 very sparse or evanescent.

 Nunquam furfuraceo-atomifera^. 



* Corolla laete alba vel cserulescens, concolor, late rotata, fauce to- 

 mentosa : antheroe lutesB vel cajrulescentes : calyx fructifer bacca 

 repletus, subglobosus : pubes simplex. Annua?. 



2. P. GRANDiFLORA Ilook. ; Gray, Man. ed. 5, p. 381. — Michigan 

 to Saskatchawan. Corolla an inch to fully an inch and a half in diam- 

 eter. Pubescence of young parts villous and viscid. Pedicels often 

 in threes. Orifice of fruiting calyx open at maturity. 



3. P. Wkightii. Humilis, diffuse ramosa, subglabra, pube minima 

 perbrevi parca ; foliis oblongis plerumque sinuato-dentatis repandisve 

 basi acutis (pollicaribus) ; pedicellis filiformibus floi^e calyceque fructus 

 (semipollicai'i) longioribus ; corolla ut videtur alba diametro ultra- 

 semipoUicari ; antheris aut caaruleo tinctis aut luteis (in sicco). — 

 Prairies along the San Pedro River, Southwestern Texas, C. Wright, 

 no. 1 G02. Apparently the same at Fort Yuma on the Rio Colorado, 

 Schott, Thomas, in herb. Torr. ; but the specimens are insufficient. 



* * Corolla flavida, luridi-ochroleuca, seu viridula, fundo fere semper 

 fusco vel brunueo-purpureo. 



H— AnnuiE, fere glabrse, nee stellate- nee viscido-i:)ubescentes : antherse 

 violacea3. 



+♦ Parviflorae : calyx fructifer amplus vesicarius, primum carinato- 

 angulatus basi umbilicatus, maturitate subrepletus, dentibus conni- 

 ventibus clausus : caules ramique insigniter angulati : petioli elongati.
