Rivea campanulata House in Muhlenbergia 5 (1909) 72. 
G. E. S. 93, local names alalag, abubo. 
A species of wide distribution in the Indo-Malayan region, introduced 
in other tropical countries. 
In adopting both the generic and specific name of this species much 
depends on interpretation of types, and differences in interpretation accounts 
for many of the synonyms cited above. Dr. House claims that the actual 
type of the genus Rivea is the same species that Hallier more recently 
selected as the type of the genus Stictocardia, but there may be a difference 
as to interpretation for Choisy includes in Rivea, in its original place of 
publication, more than the single species Rivea tiliaefolia, judging from 
Index Kewensis. I am, hence, content to retain Stictocardia in the sense 
that Hallier proposed it, but I do not accept his specific name tiliaefolia, 
which is antedated by Ipomoea paniculata Linn. Hallier™ states that the 
specimen in the Linnean herbarium under Ipomoea campanulata is Thes- 
pesia populnea Corr., and in this he is certainly correct. B. Daydon Jack- 
son, Secretary of the Linnean Society, informs me that the specimen is 
named campanulata by Linnaeus himself, and that Sir J. E. Smith has 
pencilled on the sheet “Hibiscus populneus J. E. S.” The species is checked 
off in Linnaeus’ personal, interleaved copy of his Species Plantarum indi- 
cating that the specimen was in the herbarium if not before the Species 
Plantarum was published, at all events a very few months afterwards. 
However, as to the actual type, the first reference under Ipomoea campanu- 
lata is to Adamboe Rheed Hort. Malabar. 11: 115, t. 56 which is Sticto- 
cardia tiliaefolia=Stictocardia campanulata, and to which the first part of 
Linnaeus’ description manifestly applies. The last part of the description 
apparently applies to Thespesia populnea Corr. I maintain that the species 
is to be typified by Rheede’s figure, not by the specimen in the Linnaean 
“ Meded. Rijks Herb. 1 (1910) 26.
