tost, scouleri Lind. bot. reg. 1277. Suffruti- 
cose, leaves cuneate serrate, upper linear ob- 
tuse entire, flowers subracemose second— Ori- 
gon, large purple flowers. Akin to Dasanthe- 
ra fruticosa 397. 
411. Apentostera triflora Raf. Chelone! 
ne in or os a Lind. bot. reg. 1211. Herbaceous, 
leaves ovate acurn. serrate, upper amplex. cor- 
date, peduncles axillary triflore — Origon, quite 
similar to the last in the structure of flowers, 
yet put into a different Genus by Lindley ! 
412. LEPTEIRIS Raf, (minute sterile) 
calix 5parted, corolla tubulose incurved beard - 
ed inside, limb 51obed subequal. A minute ru- 
diment of a fifth sterile stamen. Leaves oppos. 
narrow, flowers glomerate verticillate whitish 
- — another and nearer link to Pentostemon, dis- 
tinct from it by corolla and habit quite pecu- 
liar : akin to Russelia and Pagesia. 
413. Lepteiiiis parviflora Raf. Pentoste- 
mon micranthum Nut. cat. 83. Smooth, leaves 
linear lanceol. acute entire subamplex. flowers 
spicate paniculate glomerate in whorls, seg- 
ments of calix lanceolate — Origon, stem slen- 
der pedal, seen dry, collected by Wyeth. 
I must end here this long survey of the Gen- 
era akin to Gerardia, without attempting yet 
all those akin to Pentostemon. They are fur- 
ther removed from Digitalis to which Nuttal 
compared them. Thus we have already 12 Gen- 
era and 40 sp. of plants akin to Gerardia or once 
added thereto, many of which are quite rare 
plants seldom seen by our botanists; some are 
beautiful and yet hardly known in Gardens. 
There must be others in the Missouri and Ori- 
gon regions. It is a fact that in this tribe the 
colors of flowers indicate Genera ! I have not
