PENTSTEMON. Supra, vol. 13. fol. 1121. 
P. pulchellum; caule herbaceo pubescente, foliis sessilibus lineari-oblongis 
serrulatis glabris, panicula simplici secunda, calycibus pubescentibus, 
corollis ventricosis subpilosis eglandulosis, palato villoso, filamento 
quinto barbato, staminibus tubi longitudine. 
Caulis erectus, ramosus, 14-pedalis, leviter pubescens. Folia lineart- 
oblonga, serrulata, glabra, suprema sessilia, subamplexicaulia. Panicule 
lterminales, simplices, subsecundi, pedunculis sub-bifloris, bracteis longioribus. 
Sepala pubescentia, subglandulosa. Corolla violacea v. lilacina, pubescens, 
eglandulosa, ventricosa, albo venosa, laciniis subequalibus, palato maculato, 
villoso. Stamina glabra, suprema tubi longitudine, quandoque exserta ; fila- 
mentum quintum his equale, apice barbatum. 
A handsome, half-hardy perennial, native of Mexico, 
whence seeds were brought, in 1826, to Mr. Tate, of Sloane 
Street, in whose Nursery our drawing was made, in July 
last, by Mr. R. P. Staples, to whom the same collection 
owes many other valuable plants. We understand that it 
throve exceedingly, planted in a warm border exposed to 
the south. 
This is very near P. campanulatum, from which it 
differs principally in its corolla being paler, more inflated, 
and destitute of glands, which abound on the corolla of 
P. campanulatum. The leaves of this plant are also less 
finely toothed, not so much acuminate, and of a more 
oblong figure.* 
* Tt is to be observed, that Professor Sprengel’s definition of P. cam- 
panulatum is so erroneous, that it is to be doubted whether he can possibly 
haye intended the true plant.
