This is clearly the Cuscuta compacta of Choisy’s monograph, (and of DC. prodr. 
excl. syn.) described after specimens collected in Alabama and Georgia; the notice 
in Silliman’s Journal, Vol. XLIV. p. 195, must therefore be corrected. — It is very 
near Cuscuta (Lepidanche) adpressa, which thus far has only been found on the 
bottom lands of the Mississippi and Illinois Rivers. This is again a remarkable 
instance of two nearly allied species, one growing in the mountainous region of the 
Southern States, the other one in the western lowlands. Analogies offer in Baptisia 
alba and leucantha, Phacelia fimbriata and Purshii, and others. The mountain 
species is distinguished from its western relative by the closer and compacter glome- 
rules, and much more slender and mostly smaller flowers. The tube of the corolla 
exceeds the compact scales of the calyx considerably, and is much narrower in pro- 
portion to its length; it gives, therefore, to the capsule which it covers, a much 
more pointed appearance, though the capsule itself is nearly globose. This appear- 
ance of the vestiges of the corolla on the capsule distinguishes this species from 
C. adpressa just after flowering. The corolla appears to be more membranaceous 
than in the western species, and remains whitish when well preserved in the herba- 
rium; the other usually turns reddish-brown.
