408 M. A. Curtis on New and Rare Plants. 



i 



peduncle, alternating on different sides of the stem from the sec- 

 ond or third pair of leaves to the summit. Follicle ? 



Sandy pine woods of Cumberland Co., N. Car., west of the Cape 

 Fear; also, Society Hill, S. C, where it was detected by my 

 young friend, Miss Serena Williams. Flowers May, June. Has 

 very much the aspect of Acerates, and, like A. viridiflora, varies 

 exceedingly in the form of the leaves. 



Fraxinus platycarpa, Michx. &. pubescens. — Young branches, 

 petioles and underside of folioles, softly tomentose. 



F. platycarpa, Mickx. y. oblanceolata. — Glabrous. Samaras 

 oblanceolate. — For these two forms of F. platycarpa I am in- 

 debted to my generous correspondent, Mr. Ravenel, who sent them 

 from the region of the Santee Canal. The species can hardly 

 be confounded with any other, though apparently subject, as are 

 probably the other species, to considerable variation. These va- 

 rieties, like the more common form, frequently have the samaras 

 three winged. The calycle is not noticed by Michaux either in 

 his description or figure, but it is as conspicuous as in any other 

 of our species. 



Quercus Georgiana, n. sp. — Dwarf. Leaves small, petioled, 

 very smooth, somewhat obovate in outline, cuneate and often 

 unequal at base, 3- mostly 5-lobed, the lobes triangular lanceo- 

 late, acute, mostly entire. Cup subpeduncled, saucer-shaped, the 

 scales very smooth and closely appressed, margin thin, enclosing 

 about one-third of the oval-globose acorn. 



"Growing in clusters like Castanea pumila, 6-8 feet high, and 

 bearing abundantly," very smooth. Leaves, including the peti- 

 ole, 3-4 inches long, smooth and shining, the underside a little 

 paler. A small villous tuft is found in the axial of one or two ot 



the largest veins beneath. Petiole £-f inch long. Sinus of the 



leaf rounded, extending about §■ the way to the midrib. Acorns 

 h inch long, subglobose, marked longitudinally with pale lines. 

 This species is nearest allied to Q. palustris, but differs in its 

 small size, smaller and differently shaped leaves. In the outline 

 of the leaves and in the fruit, it has some resemblance to Q, ilicl- 

 folia ; but the leaves are smooth, much larger and differently cut. 

 fruit smaller and the cup less top shaped. — Stone Mt., Georgia.

Cyperus Iria, Linn.— Santee Canal, S. Car., Mr. Ravenel 

 — This interesting addition to our Flora I had taken for a new 

 species and intended dedicating it to its discoverer, but Dr. Tor- 

 rey, on the authority of a specimen from Nees, refers it as above. 

 It was before known as a native only of the East Indies, China 



i 



and the Philippines. In the florets it has a remarkable similarity 

 with C. flavicomus, but in the character of the inflorescence and in 

 the seed it is very distinct.
