124 CONTRIBUTIONS TO WESTERN BOTANY NO. U 



The type specimens and localities were accidentally omitted from th? 

 following: 



Pentstemon flaviflorus Jones Cont. 12 66. Colonia Juarez, Mexico, 

 September 12, 1903, 6,000 feet altitude. 



Collinsia Brucae Jones Cont 12 69. Little Chico, California, June, 

 1897. Na 2063, Mrs. Bruce. 



In regard to the blunder in my key referred to by Femald I would 

 .say that the error arose in my finding other material with more leaflets 

 than in tjie type species and which I referred to the type, but I failed to 

 correct my key accordingly. This would tend to vitiate Fernald's new 



species.

 first on the page.

Himantostemma Pringlei Gray. This plant seems to grow at La Paz. 

 Certain things which Gray failed to see in this plant are very peculiar. 

 The very' rough pubescence is made of tapering hairs which are warty 

 and stand out straight from the stems and leaves. The bark is very 

 corky and splits up into rectangular areas. The copious hairs on the 

 ipside of the corolla are flat and ribbon-like, and mostly white and about 

 .1- long as the appendages. The outside of the corolla is hairy like the 

 lexi\-e3 .toward the tip and the segments are conspicuously 10-veined.
