Empetbaceae. 



179 



Corema. Broom Crowberry. 

 (Family Empetraceae). 



Low spreading shrubs: ever- 

 green. Twigs tender, ridged be- 

 low the leaf-scars: pith minute, 

 continuous. Buds solitary, sessile, 

 compressed round-ovoid, minute, 

 with 2 or 3 scales. Leaf-scars 

 subverticillate, minute, half-round, 

 somewhat raised: bundle-trace 1, 

 indistinct: stipule-scars lacking. 

 Leaves linear-oblong, revolute to 

 a dorsal slit, microscopically den- 

 ticulate. 



Though very different in tech- 

 nical characters, the Empetraceae 

 are suggestive of Ericaceae in 

 vegetative characters. Anatomi- 

 cal comparisons are made by Gi- 

 belli in volume eight of the Nuovo 

 Giornale Botanico Italiano, and 

 by Mori in the same journal for 

 1877; and an instructive lecture 

 by Miall, in which their inrolled leaves figure, is published 

 in volume 58 of Nature. The leaf-anatomy is discussed com- 

 paratively by MacEwan in the Bulletin of the Torrey Botani- 

 cal Club for 1894. 



Corema Conradii has borne the generic names Tucker- 

 mannia, given it by Klotzsch in 1842, but already in use for 

 another plant, and Oakesia, given it by Tuckerman in the 

 same year, both botanists failing to identify the supposedly 

 new genus with the earlier named Corema. 

 Glabrate on the ridges: bark exfoliating. C. Conradii.
