4. loNiDiuM FRUTicuLOSUM (Benth. Bot. Voy. Sulph. p. 6, t. 2) : 

 var. DENTATUM : caulibus herbaceis 9-pollicaribus ; foliis lanceolatis 

 seu linearibus, majoribus argutissime dentatis. — This must belong to 

 Bentham's I. fruticulosum, a bad name ; for in our plant the stems are 

 wholly herbaceous, and I am not sure that the indurated and stout root 

 is really perennial. The leaves vary from linear to broadly lanceolate, 

 and the larger ones especially are beset with sharp salient teeth. The 

 short peduncles, flowers, &c., accord with the published character and 

 figure. 



5. Dryjiaria frankenigides, H. B. K. Nov. Gen. «S; Sp. 6, p. 

 21, t. 515 ; Torr. in Mex. Bound. Surv. 2, p. 36. Spergularia rupes- 

 tris, Benth. Bot. Voy. Sulph. p. 17? non Camb. The leaves are nar- 

 rower than in the figure above cited, and the small intermediate lobes 

 of the petals are three instead of four ; otherwise there is no obvious 

 difference, and No. 698 of Coulter's Mexican collection (from Zima- 

 pan) is intermediate in appearance. Without examining the petals 

 the plant might naturally be taken, as I suppose it was by Bentham, 

 for a Spergularia.

10. Sph.eralcea incana, Torr. in Gray, Fl. Fendl. p. 23, «& 

 Bot. Mex. Bound, p. 39. One of the less canescent forms. 



11. Hibiscus (Bombicella) kibifolius (sp. nov.) : fruticosus, 

 humilis, fere glaber; stipulis setaceis persistentibus ; fohis rotundatis 

 subcordatis crenato-dentatis saepe trilobis chartaceo-membranaceis venu- 

 lis reticulatis ; pedunculis axillaribus unifloris folio longioribus sub 

 apice articulatis ; involucello 8 - 9-phyllo, phyllis lineari-setaceis calycis 

 lacinias ovato-lanceolatas subsuperantibus corolla (purpurea?) triplo 

 brevioribus capsulam subglobosam aequantibus ; seminibus in loculis
