This ought perhaps to be considered as merely a species of 

 Phytolacca^ rather than as a distinct genus. It differs from 

 Phytolacca chiefly in the inequality of the lobes of the calyx, 

 the ascending stamina, and the absence of an elevated central 

 axis, leaving the ovaria entirely free at their inner edge.

The flowers are by far the largest of the whole family, of 

 which it may justly be reckoned the most showy genus. The 

 long filaments essentially distinguish it from Lithospermum and 

 Batschia, to which it otherwise comes nearest in affinity. The 

 Boragincte may be divided into five very natural groups, dis- 

 tinguished by the form and structure of their corolla. The 

 Jirst, consisting of Borage, Trachystemon *, Trichodesma, and 

 perhaps also Rindera, characterised by a deeply-parted corolla, 

 with pointed segments, exserted stamina, and a diffuse inflo- 

 rescence, may be termed Boragece. The second may be deno- 



• This genus is founded on Borago orientalis, which differs essentially 

 from Borago, by its lengthened hairy filaments ; by its incumbent, pointless 

 anthers; and lastly by the blunt abbreviated processes of the corolla.
