340 Harper: BoTANICAL EXPLORATIONS IN GEORGIA 
have seen (mostly from Georgia), agree very well with Michaux’s 
description and are easily distinguished from A. rubra, a plant of 
more northern range, by the shape of the leaves, which appears 
to be quite constant. But as this is about the only difference, it 
seems best to treat Michaux’s plant as a variety of A. ruédra. 
This may possibly have been done before, but it would be impos- 
sible to ascertain this without wading through a great mass of 
literature. Michaux himself did not contrast the two plants, as 
he did not mention A. rubra. Miss Vail, who has seen his type 
specimen, which was found ‘secus amnem Althamaha, in 
Georgia,’ says that my specimens resemble it very closely. In 
the Columbia University Herbarium are specimens of the same 
plant collected in Georgia by Dr. Boykin and Dr. Chapman (with- 
out definite locality), and in Louisiana by Dr. Hale. 
‘Nama ovata (Nutt.) Britton. (Hydrolea ovata Nutt.) 
Collected in shallow water in the Slough near Camilla, Mitchell 
County, August 8 (no. 1170). I know of no other definite sta- 
tion in Georgia for this species, which is more frequent farther 
west, It is remarkable for being one of the few aquatic or semi- 
aquatic plants which are both pubescent and spiny. The spines 
are sufficiently numerous to make collecting disagreeable when 
one has to wade in after it barefooted. 
COLLINSONIA TUBEROSA Michx. 
In rich shady woods on the north side of a bluff of Oostanaula 
shale east of Dalton, Whitfield County, at 720 feet altitude, Sep- 
tember 7 (no. 1287). Has very much the babit of Phryma Lef- 
tostachya, which grows with it, and its flowers have almost exactly 
the same odor as those of Dicerandra odoratissima, This Col- 
ae : ae 
onia seems to be quite rare, but it is imperfectly understood 
and its nomenclature is somewhat uncertain 
Linaria FLoripana Chapm. 
Collected on the rosemary sand-hills of Emanuel County, 
June 28 (no. 976) ; evidently long past flowering, and with over — 
ripe capsules. Previously known only from drifting sands along 
the Gulf coast,
