No. 739. In Herb. Kew. ; 
This is a bright species which I have described from Purdom’s 
dried specimens in Kew Herbarium. Messrs. Veitch have been 
so good as to present to the Royal Botanic Garden a living 
plant of a Primula raised from Purdom seeds said to be of this 
plant, but in its growth so far—it is not a plant of easy cultiva- 
tion—it does not show the characters of Purdom’s dried speci- 
mens, but rather impresses me as being the plant described by 
Maximowicz as P. flava, Maxim.* I have seen no example of 
Maximowicz’s plant, and Purdom’s dried specimens differ 
conspicuously from the description of P. flava, Maxim. in the 
petioles, which are long and narrow (not broad) 
shorter than the foliage (not ‘‘ much longer ’’) 
puberulous calyx not tubular and mealy, 
slightly) shorter than the pedicels. It must be remembered 
however, that P. citrina, Balf. fil. et Purdom is described from 
* Maxim. in Bull. Acad. St. Petersb. XXVii (1881), 497.
