66 ANNALS OF THE MISSOURI BOTANICAL GARDEN 
are united at the base into a short style, a peculiarity which 
has appeared apparently independently in 7. pusillum. The 
nearest relative of T. Catesbaei is probably T. cernuwm, from 
which the main distinctions are as follows: In T. cernuum 
the leaves are rhombic, 3-nerved, acuminate, and more or less 
cuneate at the base; in Т. Catesbaei they are elliptic or oval, 
5-nerved, acute or acuminate, and constricted at the base into 
a short petiole. The peduncle is nodding in 7. cernuwm, and 
strongly recurved or sometimes declined in T. Catesbaei. The 
petals in Т. cernuum are elliptic, oval or ovate, about 2 cm. 
long, acute or obtuse, revolute, white or pink; in T. Catesbaei 
they are oblong or oblong-lanceolate, reaching more than 4 
em. in length, obtuse or abruptly pointed, crisped, recurved, 
pink or rose-color. In Т. Catesbaei the stamens are much 
longer, reaching 18 mm. (8 mm. in T. cernuum), and Ше fila- 
ments are longer than the bright yellow recurved anthers. 
Yet another difference exists in the absence of a style in 7’. 
cernuum and its relatives.

29. T. affine Rendle, Jour. Bot. 39: 334. 1901. 
This species is known only from specimens collected by 
Rugel in Georgia. It evidently belongs with T. Catesbaei 
from which it is differentiated, aecording to Rendle, by its 
** broader sepals, smaller not undulate petals, shorter stamens, 
and leaves broader above the middle.’’ The filaments in par- 
ticular are only about 4 mm. long. 7. affine recalls 7. cer- 
nuum in size and habit of leaf and flower, but like Т. Catesbaei, 
differs in its longer stamens exceeding the stigmas, and in the 
union of the latter at the base.
