point to accept, and one that could only be adopted if 
ft. Schaueriana be treated as a very variable species which 
includes R. calvescens as well. A figure of R. Schaueriana 
has been given at t. 4147 of this work under the name 
R. lilacina. It differs from R. Devosiana in having firm, 
somewhat shining leaves that are almost or quite glabrous, 
in having larger lilac to purple flowers, and in having a 
different ovary. In this work, however, two other plants 
that approach even more closely to R. Devosiana than 
R. Schaveriana does have also been figured ; one at t. 4366 
as Strobilanthes lactatus, the other at t. 5106 as Dipterac- 
anthus calvescens. Of these the former is readily distin- 
guishable from R. Devosiana, because its leaves are very 
like those of A. Schaueriana ; it differs from &. Schaueriana 
in having a more slender ovary. The latter, which is 
believed to be the same as R. calvescens, differs con- 
siderably from R. Devosiana as regards the indumentum on 
the stem and leaves and has an ovary like that of the plant 
figured as Strobilanthes lactatus. It is, however, necessary 
to remark that, in his review of the Acanthaceae under culti- 
vation in collections, the late Col. Beddome has placed two 
of these four plants under R. solitaria, a species only 
known from Velloso’s figure and his rather meagre descrip- 
tion, while Nees has referred &. solitaria to R. Schaweriana. 
In view of this dubiety all that can with safety be said is that 
&. Devosiana, here figured, belongs to a group of species 
of which #. Schaueriana is the best-known member; that it 
is readily distinguishable from the other members of this 
group already in cultivation; and that, from the garden 
standpoint, it is desirable to accord it separate recognition. 
The plant from which the material for our figure has been 
obtained was received at Kew in 1903 from the Jardin des 
Plantes, Paris. It forms a compact little shrub and is 
useful to grow as a trailer or basket-plant in a warm house. 
Its flowers are produced in autumn.
