ABRUS. This tropical Genus extends to 
Florida ; but our Sp. has not been described s 
the A . precatorius is said to have 3 varieties 
with red, white and yellow seeds. They must 
be again compared, also, the Asiatic, Antillian 
and Floridan plants. Linneus once mixt those 
plants with the Glycine. 
ABUTILON. Tournefort, MaJvinda Dil- 
len, Sida Linneus &c. This good old Genus 
hardly preserved except by Adanson, is per- 
fectly distinct from Sida by the many truncate 
and 3 seeded capsules around a hollow in a 
stellate and campanulate form, 10 to 20 with as 
many styles, the Sida having only 5. There 
are many species of it ; not yet well distin- 
guished, perhaps all the multicapular Sidas of 
Linneus belong to it, or to the Genus Dia~ 
desma.
