Rupseckta? Porrert, p. 83 (note), has been found anew by H. W. Ravenel, Esq., during the past sum- 
mer, in the mountains of Georgia. A capitulum, just received in a letter from my friend Mr. Curtis, exhibits 
the fructiferous disk considerably prolonged, and the ripe achenia short and thick, obscurely quadrangular. 
The subjoined is a Cruciferous plant which was not received in time to be noticed in the proper place : — 
SYNTHLIPSIS, Nov. Gen. Crucif.-Thlaspid. 
Calyx basi subaequalis, sepalis linearibus laxis. Petala obovata, ungue lato. Discus hypogynus inter petala 
et stamina annularis, contorto-undulatus. Filamenta edentula, filiformia. Ovarium oblongum, multiovulatam, 
Stylo gracili brevius: stigma depresso-capitatum. Silicula septo contrarie compressa, oblongo-elliptica, emar- 
ginata (vel immatura leviter obcordata) ; valyis navicularibus acutissime carinatis, apteris, apice tantum mar- 
ginato-subproductis ; septo lato-lineari uninervi. Semina in quovis loculo 8-10, biserialia, e funiculo libero 
pendula, orbiculata, compressa, immarginata. Cotyledones plane, septo contrarie, radicule adscendenti cari- 
_ nam valvarum spectanti accumbentes. — Herba ramosa diffusa, pube stellata canescens; foliis sinuato-pinnati- 
hin racemis laxis; floribus ut videtur roseis ; pedicellis fructiferis patulis vel recurvis, 
S. Greco. — Valley near Saltillo, Coahuila, January 4, 1847, Dr. Gregg. — Root and radical leaves not 
seen. Stem apparently low, diffusely branching, rigid ; the branchés, like the whole plant, whitened with a close 
and fine stellate pubescence, leafy. Leaves oblong, coarsely sinuate-tédthed or pinnatifid ; the lower naxrowed 
into a petiole ; the others almost sessile. Petals 3 lines long, evidently tinged with purple or rose-color. Pods 
4 or 5 lines long, and 2 lines or a little more in width, canescent, about the length of the pedicel, flattened 
contrary to the narrow septum, pretty strongly emarginate at the apex, tipped by the slender style; the com- 
gereein ES a pne-erred valves sharply carinate, but the keel scarcely if at all margined, except ai the 
' it is | y produced. — The specimen upon which this evidently new genus is founded 
‘¢ollection Dr. Gregg, long since forwarded to me by Dr. Short, but which has only now come 
to jiaiel Although the genus must be referred to the Thlaspidez, its nearest affinity is with Vesicaria through 
‘the Mexican V. argentea, Schauer (which I have in fruit from Coulter’s Mexican collection, no. 691), in 
which the silicle is evidently somewhat compressed contrary to the elliptical septum, but the cotyledons are 
still parallel with it; and with Physaria (vide Gray, Gen. IIl. 1. p- 162) through P. Geyeri (Vesicaria Geyeri, 
Hook.), i in which, moreover, the seed hangs with the cotyledons contrary to the septum, as in the present genus. 
It is also allied to the Californian Lyrocarpa, Hook. § Harv. In aspect it bears considerable resemblance to 
the Dithrea Wislizeni of Engelmann ; —a flowering specimen of which, gathered by Mr. Gordon, near the 
sources of the Canadian, exhibits a pair of ovules in each cell. The name, civOAnfis, compression, alludes 
to the character of the pod which distinguishes the genus from Vesicaria and Physaria. 
_ Dr. Gregg’s collection also contains specimens, gathered “west of Parras,” of a canescent ‘plant with 
ainsi the habit of Synthlipsis Greggii, but with linear-oblong pods (siliques rather than silicles), a cordate- 
capitate stigma, &c.: but the immature seeds seem as if the cotyledons would be incusphasi es a materials ; 
are Fequisite for its proper determination. — Pag: CO gee “Aw ; 7 A
