hood the upper part of the globose capsule. — It appears to 

 be an intermediate form between Cuscuta proper and Lepi- 

 danche. The var. § has larger and thinner flowers, of paler 

 color, and the lobes of the corolla lanceolate and acute. Engel.

1 An undescribed North American species, collected in the A lleghanies of Vir- 

 ginia and North Carolina by Dr. Gray and Mr. Sullivant, in the autumn of 1843, is 

 here appended. (This was named G. oxycarpa, 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 corolla; globoso-campanulato calycis segmenta 

 ovata obtusa leviter crenulata et lacinias limbi ovatas obtusas patentes (demum 

 reflexas) duplo superante; staminibus limbum subsequantibus ; squamis fimbriatis 

 (convergentibus?) basi inter se connatis ; stylis filiformibus ovarium stylopodio 

 ejusdem longitudinis coronatum pyriforme sub;equantibus ; corolla marcescente ad 

 basin capsula; (maxima?) acutatae 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 Urlica, 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. vulgivaga. The 

 large pointed capsule would seem to characterize it at once ; but C. vulgivaga 

 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 . vulgivaga 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. (Lepidanche) compacta (Choisy) : caule ramoso; floribus sessilibus glome- 

 ratis 5-partitis ; sepalis sub-novem leviter crenulatis orbiculatis concavis adpressis,
