1 An undescribed North American species, collected in the Alleghanies of Vir- 
ginia and North Carolina by Dr. Gray and Mr. Sullivant, in the autumn of 1843, is 
here appended. (This was named C. orycarpa,n. sp.; but, just as these sheets 
are going to press, Dr. Engelmann writes that Mr. Shuttleworth has distributed the 
same plant from Rugel's collection, with a printed label, under the name of C. ros- 
trata, which he therefore now substitutes for his own. A. Gr.) 
C. rostraTA (Shuttlew. in coll. Rugel): caule ramoso; floribus pedunculatis 
cymoso-umbellatis 5-partitis; tubo corolle globoso-campanulato calycis segmenta 
ovata obtusa leviter crenulata et lacinias limbi ovatas obtusas patentes (demum 
reflexas) duplo superante; staminibus limbum subequantibus; squamis fimbriatis 
(convergentibus ?) basi inter se connatis; stylis filiformibus ovarium stylopodio 
ejusdem longitudinis coronatum pyriforme subequantibus; corolla marcescente ad 
basin capsule (maxime) acutate persistente.— Alleghany Mountains from Vir- 
ginia to South Carolina, (Mr. Buckley! 1842.) Prof. Gray and Mr. Sullivant ! 
1843. — August to October. — Particular localities recorded by Messrs. Gray and 
Sullivant are: Grandfather and Negro Mountains, N. Carol.; Tygart’s Valley, Va. ; 
and ‘common in moist, shady ravines in western Virginia.” The specimens which 
came under my observation grow on Urtica, Rubus, Aster, Solidago, Rudbeckia, and 
some other plants, 
After repeated and careful investigation, and with some hesitation, I have ad- 
mitted this mountain plant as a distinct species, different from C. rulgivaga. The 
large pointed capsule would seem to characterize it at once; but C. rulgivaga 
offers so many different forms and sizes of the capsule, that other characters were 
necessary ; and they are found in the tissue of the corolla, which is ever destitute 
of the large pellucid dots constantly observed in C. vulgivaga, but is composed, 
especially about the tube, of regular, somewhat elongated, hexangular cells, easily 
distinguishable in dried specimens with a common glass. In the common species, 
the cells are linear, mostly much elongated, interspersed with the large air-cells, 
which have been frequently mentioned. The flowers are mostly twice as large as 
in C. vulgivaga, but of the same shape and proportion, about 2, and sometimes 
(especially in Tygart’s Valley specimens) 3 lines long; but the elongated ovary, 
whose stylopodium is nearly as long, though only half as thick, as the ovary proper, 
distinguishes it at once even from those forms of C. rulgivaga where the stylo- 
podium is unusually large. The filiform styles are at first about the length of the 
stamina, but soon after they are long exserted. The capsule is very large, fully 
3 lines long, globose, attenuated to a bifid point; it is larger and more acute than in 
any other known American species.— During the same journey, the following 
species was abundantly collected : 
C. (Leripancue) compacta (Choisy): caule ramoso; floribus sessilibus glome- 
ratis 5-partitis ; sepalis sub-novem leviter crenulatis orbiculatis concavis adpressis,
