7. B. ORNATrssiMA. Dowmngia omatissima, Greene, Pitt. 



H. 80 (1890), A small species of the lower Sacramento ; the 

 form of the corolla very peculiar. 



8. B. TRICOLOR, Downingia irwolor, Greene, Pitt. ii. 79

9. B. CONCOLOR. Doivningia concolor^ Greene, Bull. Calif. 

 Acad. ii. 153 (1886). Same habitat as numbers 7 and 8; the 

 most showy species of the genus. ^ 



Mr. Howell of Oregon expresses the opinion that in his 

 region there are two other species besides the well known 

 B, elegans ; and he is a most minute observer and faithful 

 reporter in all matters relating to botany. But I have seen no 

 specimens of his, nor has he supplied notes on the peculiari- 

 ties of the plants mentioned. One of them may perchance 

 be the long unidentified '^ Doirningia corymhosa'*^ of Kuttall, 

 concerning the merits of wliich I am unable to offer an 

 opinion; not knowing the plant except from the authors 

 insufficient description.
