able doubt that it is earlier by several months than A. praecoz of 
Martius. Linnaea came out in six parts and since Vogel’s paper 
is in the third number it surely appeared not later than the early = 
ae of 1837 and more probably in June.

This Florida species is very closely related to C. grammica — | 
Spreng. of Cuba and perhaps should be regarded only as a geo- 
graphical variant but I have seen no specimens that appear inter- 
mediate in character. Dr. Pennell’s statement, ‘‘ C. grammica.. 
differs by its appressed pubescence and conspicuously 
glands,” seems rather misleading as the pubescence is not ap- — 
pressed in the sense that the hairs lie flatly against the stem, — 
they rather strongly diverge and then curl back at the tip. The 
pubescence of C. keyensis is strictly spreading and the individual 
hairs are straight even to the tip. ‘

Specimens of C. Deeringiana hing do ce show the perennial 
root may be distinguished from material of C. brachiata only by — 
the fewer and distinctly larger seeds. The latter species is very 
closely related, indeed, to the highly variable C. fasciculata but it 
is confined essentially to peninsular Florida and seems to oa 
stantly recognizable by the depressed, rather than somewi® 
elongated, petiolar gland. 
Dr. Pennell has shown that the plant commonly known as C.
