SAFFORD: SO-CALLED UNONAS OF THE OLD WoRLD 505 
ovaries usually strigose-pilose. Ovules usually 1-seriate, forming 
a single column, sometimes subbiseriate. Style ovoid or oblong, 
recurved, with a longitudinal groove along its inner surface. Ripe 
carpels indefinite, either elongate and constricted between the 
seeds, or baccate and spheroid. 
In restoring the generic name Desmos to its proper place the 
author retains the sectional division of the genus as proposed by 
Hooker and Thomson, changing the name of Section I, from 
Desmos to Eudesmos, and adopting the name Dasymaschalon in 
its original form for Section II. Both of these sections were used 
in Hooker’s Flora of British India (1872), but a third section, 
Pseudo-Unona, was discarded in that work. In Sir George King’s 
monumental work on The Anonaceae of British India (1893) he 
retains the first two sections under their original names but sub- 
stitutes the name Stenopetalon for Section III., in which he places 
Unona stenopetala, U. crinita, and U. desmantha of Hooker together 
with U. Wrayi, described and figured by Hemsley in Hooker’s 
Icones pl. 1553. 
This section is undoubtedly composed of a heterogeneous group 
of plants and will have to be revised. Some of the species included 
in it differ so radically from the generic type, especially in the 
form of their ovaries and styles, that they must eventually be 
removed from the genus. Thus U. desmantha and U. Wrayi have 
nodding hairy swollen styles like those of the genus Polyalthia. 
The ovoid ovary of U. stenopetala terminates in an erect acute 
style, while the truncate ovary of U. crinita, as originally described 
and as figured by King, has a punctate stigma. 
In the following review of the genus I have been much aided 
by the figures in Sir George King’s Anonaceae of British India, 
above referred to, and especially by the citations of the author, 
which have facilitated reference to all the original authorities
