284. Castilleja indivisa (Engel. MSS.) : " piloso-hispi- 

 da ; foliis integris lineari-lanceolatis acutis basi pleraque rotun- 

 datis, floralibus apice ovato- vel obovato-dilatatis coloratis ; 

 spica demum elongata ; calycis lobis late obovatis apice colora- 

 tis truncatis retusisve corolla paulo vel vix longioribus. — Valde 

 affinis quoad flores C. coccinece, et quoad folia C. lithospermi- 

 folicn, ab ilia imprimis foliis indivisis, ab hac statura saepius 



elatiore differt, foliis acutioribus et capsulis majoribus."

 Colorado : March to June. Also collected by Drummond and 

 Berlandier. 



285. Hedeoma Drummondii, Benth. : but the verticillastri 

 are only about 3-flovvered, and the corolla is long and much 

 exserted. Yet it is certainly the same species as Nos. 276 

 and 278 of Drummond's Third Texan Collection. — Sandstone 

 rocks near Industry. July. The whole plant has the taste 

 and odor of lemon-peel. 



The two following Labiate plants, upon which Dr. Engel- 

 mann proposes to establish two new genera, viz., No. 286. 

 Stachyastrum (so called from the resemblance of the plant to 

 Stachys in habit) ; and 287. Brazoria (from the habitat on 

 the river Brazos,) we think may, notwithstanding minor dif- 

 ferences, be properly associated in a single genus, which will 

 be well distinguished from Physostegia by the inflated bilabiate 

 calyx which becomes closed in fruit by the inflexion of the 

 lower lip. The genus should perhaps be referred to the tribe 

 Scutellarinere rather than Stachydese. It may be thus charac- 

 terized.
