PENTSTEMON. — Suprd, vol. 13. fol. 1131. 



P. venustum; caule sufFruticoso erecto glabro, foliis sessilibus rectis ovato- 

 lanceolatis acuminatis denticulatis glabris, floribus paniculatis, corollis 

 ■ ventricosis ciliatis, calycibus glaberrimis, antheris pilosis. 



P. venustum. Douglas in herb. Hort. Soc. 



P. diffusa vald^ affinis, prcEcipue differt caule magis erecto, foliis sessilibus 

 longioribus rectioribus, corollce colore obscuriore, calycibusque glaberrimis. 



Found by Mr. Douglas in the dry channels of rivers 

 among the mountains of North-west America. It increases 

 freely either by seed or cuttings ; but is less handsome 

 than P. diffusum or ovatum. To be grown in perfection 

 it should be treated as a biennial : it is apt to become 

 unsightly when old. 



Very like P. diffusum, from which it is known by its 

 more erect habit, its leaves being sessile, not stalked, and 

 longer and more straight, in the colour of the flower being 

 less lively, and in the calyxes being perfectly smooth. 



Flowers in great profusion during the months of July, 

 August, and September. 



We may here remark, what it is extremely important to 

 those who are in possession of seed of the rare Pentstemons 

 to know, that this seed cannot be raised in heat; it is indis- 

 pensable that it should be sown in a cold frame, or all 

 endeavours to raise it will prove fruitless.
