Are now any xaxistxssxkHMT varieties known- of yyraphaea odorata 
Eardlyt But only ve-^y doiibtful,. Already Purschr characterizes bis 
var> rosea not only by color but also by leaf-form. For N3nnphaea 
odorata I~ he sayss: N. folio orbiculato-cor*dati s - subma^ginali s 
lobio divericatis.acumin^fus obtuso, for var, ^ rosea ; : f ollis cor- 
datis obtusio, lobio divericatis.acutis«. These differences seem- to 
me to shatter into nothin^,and that once according to analogy of 
Nymphaea alba , where the same difference of the form of the lear 
is found on the same stem:- and change, according to the material^ 
available and proven by me. The main form was to have according ta 
Pursch' leaves' lobis divericati s% which is not always the case. 
Quite frequently the lobes Stretch^ very wide,and that as well for 
the main form as with var, , With the main form the leaf is sup- 
posed to be subemarginatumv for var.^ obtusunr,, I find it often 
with var,^ emarginatiim and for the main form obtusioir, and, on top 
of it,, for both aiDice subacuminatum. In other cases, as e.g. B. 
Sims l.c.t. 1652 presents for var.^ the lobes o^ I are supposed to 
have acTimen obtusum^^for var . however acuti; and are for both forms 
( I and var» ^ ) the leaves lobis plus minus acuminatis, and for the 
leaves of both forms the leaf-lobes at times acuminae acuto- (also 
for the main form',as Sims shows Bot. Mag. t. 819 3 times) and in 
other cases acuminae obtuso subobli terato, . Finally, the difference 
between 1.. folio orbiculato^ co^atis and var,^, fol.cordatis does not 
make sense. I do not find any difference in the mairr shape of the 
leaf of I and var*.|^, Varieties, of which you characterize the twa 
first ones thus = OC sinno and lobis of the leaf more or less" 
rente (? E.D.)''^^ sinno and lobis more or less rounded ?^ To the 
latter form is cited' , N^reniformis Walter Car, p. 1 55, which' accor-
