Resembling T. parvum in size, but very distinct from it in the remarkably 
large flowers for the size of the plant, the leaf, calyx, and corolla characters also 
showing well-marked differences. It appears to be as distinct from T. parvum 
as T. tenerum is from T. monanthum, and to show these differences descriptions 
of all three species are given.

HeMsLEy’s description is based upon Parry and Palmer’s no. 134, although 
other specimens are mentioned. Loyacono’s description is also based upon 
a plant collected by Parry and Palmer, but no collection number is given. His 
description, however, agrees well with a duplicate of HemstEy’s type in the 
National Herbarium, and the conclusion was forced upon me that they are iden- 
tical.
