RECAPITULATION OF THE SECTIONS AND GROUPS 133 
groups, the typical one covering those species with uniserrate 
leaflets and smooth peduncles, that of Deseglise: having the latter 
hispid. The Canescentes have biserrate leaflets and smooth 
peduncles, wild there is a fourth subgroup having ner 
leaflets and hispid peduncles, to which I have placed B. cesia Sm, 
and &. Lucandiana Déségl. I feel sure now — . cesia Sm. 
should be referred to the group of BR. corisfolia, w TL 
diana Déségl. is a very rare species of which I hays! seen too little 
material, but which I think may very likely belong to the same 
group, so that there is no British representative of this fourth 
subgroup of &. dwmetorwm. The whole group is liable to be mis- 
taken for that of R. coriifolia, while the members of the ee fo 
subgroup may be confounded with those of the Stylose. Th 
absence of subfoliar glands should suffice, in most cases, to 
prevent confusion with the &. Borrert group. 
Thou have not much improved my knowledge of FR. obtust- 
folia Desy. since I wrote my paper on the Hu-canine, I still think 
it best placed in the present group. Prof. Dingler places ve 
in habit, shape of leaflets, &c., but uniserrate and sounds 
being named by him &. ———— in the absence of information 
as to the colour of the flow 
The group R. glauca, in as far as its typical forms are con- 
cerned, is a fairly distinct one. The short peduncles, —— sepals, 
and, above all, the flattish head of very woolly styles, are marked 
features, but all these may occur, collectively or individually, in 
the group of BR. canina. In the subgroup Subcanine the sepals 
are reflexed. This subgroup does vats appear to have been fully

right in referring R. cesia Sm. to it, that species should replace 
R. coriifolia as the type of the group, since R. cesia Sm. ante- 
one R. cones Fries by three years. The mem mbers of the
