are all sessile, while in /. perpusilla the culms (8 or 10 to each 
plant) are prostrate, and of the 3 to 6 spikelets in each umbel some 
are sessile and some on peduncles 1-4 mm. long. (That part of 
the original description conflicting with this is erroneous.) 
Mr. M. L. Fernald has suggested the resemblance of my 
plant to ¥. dipsacea (Rottb.) B. & H., an Asiatic species, but this 
resemblance is probably only accidental. /. dipsacea has been 
treated as the type of a distinct genus (Echinolytrum Desv.), on 
account of some peculiarities of its achenes, which find no parallel 
in my plant. It should be borne in mind that nearly all the pine- 
barren plants are endemic species, so that the probability of one 
of them being identical with an Asiatic species is very small. And 
there is not the slightest possibility of my plant having been 
introduced. 
RHYNCHOSPORA SOLITARIA Harper, Bull. Torrey Club, 
28: 468. Igor 
Collected again at the type-locality in Tifton, September 26 
(zo. 7677); also seen in similar situations in Colquitt County a few 
days earlier and in Irwin County a few days later. Since seeing 
this species in the field again I can now indicate its affinities with 
more certainty. It seems nearest related to X. ciliaris (Michx.) 
Mohr (RX. czliata Vahl), from which it differs principally in being 
more slender and glabrous, with longer erect leaves, narrower 
spikelets and longer perianth bristles, and in its later flowering 
period. These two species, together with R. Baldwinti, seem to 
form a small natural group. If my view is correct &. solitaria is 
not a near relative of R. Zracyi (which is scarcely a true Rhyncho- 
spora), which it immediately follows in Dr. Small’s Flora, 
RHAPIDOPHYLLUM Hystrix (Pursh) Wendl. & Drude 
This, one of the rarest of our palms, I first found in rich shady 
woods northwest of Cuthbert, on October 21 (wo. 1769). Here 
there were only a few specimens, but a few days later I found it 
more abundant in similar situations along Samochechobee Creek 
in Clay County. 
This species seems to have been previously known in Georgia 
only from the type-locality, “near the town of Savannah,” but I
