284. Castimiesa inpivisa (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. coccinee, et quoad folia,C. lithospermi- 
folie, ab illa imprimis foliis indivisis, ab hac statura sepius 
elatiore differt, foliis acutioribus et capsulis majoribus.”

285. Hepeoma Drummonpu, Benth.: but the verticillastri 
are only about 3-flowered, 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 
Scutellarinee rather than Stachydez. It may be thus charac- 
terized.
