The leaves are smaller than is usual in the genus, 
very sharp-pointed, with the toothing unusually 
sharp ; the uppermost leaves become gradually 
narrow, till those immediately below the flowers 
are not unfrequently linear and entire. As this 
species leafs early, the young shoots are apt to be 
killed by frost, and when this takes place no flowers are produced that season, 
as it is from the ends of the lateral shoots that blossoms always appear in this 
genus. (Bot. Reg.)

We have given this description and figure from 
Schrader and Guimpel, because in 1837 there was a 
plant in the Hort. Soc, Garden which answered to BBN Be (ly) granaifibrus, 
it, and which differs from P. specidsus in the leaves being nearly entire.
