as deseribed, but round-ovoid, and more compressed than in 
any other species of the group. hey are more than an inch 
long when well grown, nearly as broad, but less than a half- 
inch in thickness.

the genus from without: a kind of practice which, it seems 
to us, can hardly be condemned too strongly, having nothing 
to recommend it, and tending only to the further complica- 
tion of our troubles with synonomy. Although the present 
plant is one of the oldest species, it remains the only rare
