PENSTEMON Ovatus. 

 Ovate-leaved Penstenion 



Class and Order. — Didynamia Angiospermia. 

 Syn. Penstemon ovatus. Curt. Bot. Mag. N. S. pi. 2903. 



Koot fibrous, stent erect, two or three feet high — cauline leaves sessile, am- 

 plexicaul at the base, cordate, margins dentate, becoming smaller and 

 entire as they approach the summit — radical leaves, large, ovate, den- 

 tate, on long channelled petioles — flowers in fascicles, which are axil- 

 lary — calyx five segments, equal, lanceolate acute — corolla bilabiate, 

 tube purple, lip bright blue, upper lip erect, divided into two segments, 

 three lower reflexed — throat hairy — stamens four, two long, and two 

 short, curved — one barren filament, with an acute claw at the base, 

 apex hairy, style recurved — leaves, when young, of a beautiful purple 

 on the under side. 



Great additions have lately been made to this ;^enus, by Mr. 

 Dougflas, who has discovered many new and valuable plants in North 

 America, among which is the species figured. According to the Bot. 

 Mag. pi. 2903, N. S. it was found by him " growing plentifully among 

 the limestone rocks on the high moimtains about the grand rapids of 

 the Columbia river, at the distance of 140 miles from the ocean," and 

 sent to the Hort. Soc. in 1826; it likes a light loam and shel- 

 tered situation, and may be increased by seeds or parting the roots. 

 When well grown it is a very beautifid and elegant plant, and a great 

 acquisition to the flower garden. As we are yet scarcely aware how 

 it may bear the cold of our winters, it will be desirable to protect it 

 from severe frosts. The genus can now boast of many new and beau- 

 tiful species,
