lanthium was established by Clayton and Gronovius on M. Vir- 
ginicum, and thus taken up by Linnaeus, with the addition of a 
Siberian plant, which belongs to Zigadenus.* The Melan-

afterwards. — 
The rocky summits of the mountains afforded us Sedum tele-

~~. forms dense silvery tufts on the highest and most exposed peaks ; 
Veronica officinalis, serpyllifolia, and agrestis, (all certainly na- 
‘tive;) Lycopodium rupestre, in a very beautiful state, and on the 
Phenix Mountain we found a solitary specimen of L. Selago ; 
Arabis lyrata, with perfectly accumbent cotyledons; Potentilla 
tridentata, which we only saw on the Bluff Mountain ; Wood- 
sia ilvensis ; Saxifraga leucanthemifolia, which not unfrequently 
attains the height of two feet, with a large and slender effuse 
panicle; Diervilla trifida, entirely resembling the northern plant ; 
eels melanocarpa ; Sorbus Americana, 8. microcarpa ; Rho- 
lendron Catawbiense, just out of flower, while &. mazi-

Bs somewhat i in tufts, and scarcely exceeding four or five 
inches in height. The flowers, which are deep pink, while in 
the ordinary form of this region they are nearly white, present 
the dimorphism which obtains in several sections of the genus ; 
the stamens in some specimens being inserted in the throat of 
the corolla and exsert, while in others they are inserted near the 
base of the tube and included; in the former the style is uni- 
formly short and included, sna in the latter long and somewhat 
exserted. These two forms were often seen growing side by 
. The Helonias glaberrima, Bot. Mag. t. 1680, on which Zigadenus commuta- 
tus, of Schultes is founded, is Z. glaucus ; the specimens came from Fraser’s nur- 
sery, but doubtless were not derived from the Southern States. Helonias a, 
Bot. mag. t. 1703, is Z. glaberrimus, Michx., not fully developed.
