single plant of it by one of the great Continental Nurseries ; 
he adds that it has much the appearance of P. cretica, and 
is quite hardy, flowering in May. 
P. Wittmanniana is a native of cool shaded forests in the 
Caucasus and Armenia; also of North Persia, according 
to Bossier, who gives Asterabad as a habitat on the 
authority of Bunge; but Bunge’s Asterabad plant, so 
named by himself, and which he communicated to the 
Hookerian Herbarium, cannot be this species, having very 
woolly carpels. The true plant is, however, in the same 
Herbarium, collected in the Caucasus by Frick.
