appear to be attached to the side of the seed.” All this will be best

BEGONIA PHYLLOMANIACA, Mart.* 
At one of the last meetings of the Royal Bavarian Academy of Sci- 
ences at Munich, a very remarkable species of Begonia was exhibited 
by Professor von Martius, having this extraordinary peculiarity, that it 
produces from the stem, branches, and petioles, innumerable leaflets, 
which, on being detached and placed on moist ground, produce roots 
and perfect plants. In order to mark this singular property, the Pro- 
. fessor calls the species B, phyllomaniaca, being possessed by phyllo- 
. mania. Tt stands nearest to B. papillosa and incarnata; and the fol- 
lowing detailed diagnosis embraces its essential peculiarities :— 
Begonia phyllomaniaca (in serie “foliis semicordatis vel inæqualiter cor- 
datis”); caulescens, erecta; caule ramisque leviter scabriusculis pas- 
sim folia succedanea parvula innumera promentibus ; foliis (ultra 5-6 
Rervos venasque subtus parce albo-pilosos) glabris crassiusculis du- 
.. plieato-inzequaliter dentatis piloso-ciliatis, petiolis teretibus scabrius-
