Conobea (Schistophragma) intermedia, (sp, nov.); viscoso-pubescens ; foliis subpinnatipartitis; 

 floribus brevissime pediinculatis ; antherae loculis subcontiguis ; capsula ovato-Unceolata calyce 

 subinaaquali dimidio longioribus. — Dry hills around the Copper Mines, New Mexico; very 

 common ; Wright. (1485). Annual, erect spreading, 2-6 inches high, with the aspect of C. 

 (Leucospora) multifida ; only more pubescent ; the flowers very short-peduncled ; the corolla 

 twice as large, purple, or the lower lip pale. Capsule 3 or 4 lines long, pointed. This 

 connects Bentham's Conobea multifida and his Schistophragma pusilla in such a way as to 

 render it necessary to comprehend under one and the same genus these three species of closely 

 similar aspect. The pod is jast intermediate between the ovate shape of the first and the linear 

 form which distinguishes the last ; but it has the spirally striate seeds of Schistophragma. Its 

 unequal calyx (the upper sepal being somewhat larger, or at least longer than the others,) would 

 appear to exclude it from Schistophragma no less than from Conobea ; but I observe the same 

 thing, only rather less marked, in. an authentic specimen of Bentham's S, pusilla var. major, 

 from Santa Martha. The stigma is essentially the same in all three. The present species has 

 one peculiarity : while in its unequal calyx it seems to approach Heri^estis, in its anthers, (the 

 cells of which are not side by side, but one inserted a little above the other) it approaches 



Stemodia and its allies.

Seymeria bipinnatisecta. Seem. Bat. Herald, p. 323, t. 59, var. Texana: pilis glandulosis et 

 viscidis pubescens seu villosa; ramis subvalidis; foliis bipinatifidis vel superioribus pinnatifidi? 

 fiegmentis lato-linearibus obtusis inciso-dentatis ; pedicellis s^epissime brevibus ; antheris obtu- 

 sissimis ; capsulis glandulosis acutatis vel obtusis. — Upper Guadalupe river, etc. ; Lindheimer. 

 Lower Rio Grande; Wright, H?ad of the Pedro river, Sonora? Bigelow. A stouter, more 

 pubescent and glandular plant than S. pectinata, and with the leaves much more cut, sometimes 

 even tripinnatifid. The shape of the capsule varies so in the numerous specimens under exami- 

 nation that I fear it cannot be greatly relied upon in this genus. The above character was 

 drawn up, under a different name, before Seemann's plant was published. I have not seen 

 Mexican specimens. Our plant has less dissected foliage and (except in one or two instances) 

 much shorter pedicels than are delineated in Seeraann's figure, and no such incised or pinnatifid 

 calyx-lobes, (which, by the way, are not mentioned in the character.) still the two are likely to 

 fall under the same species.
