(2.) LEPIDANCHE,* n. gen. 
Calyx consisting of many imbricated scales, persistent. Co- 
rolla tubular, 5-cleft. Styles two. Capsule 2-celled, 2-seeded. 
Very similar to Cuscuta when young ; but different in appear- 
ance when in flower or fruit. The stem which connects the dif- 
ferent clusters of flowers having then disappeared, the latter 
only remain, consisting of innumerable crowded sessile flowers, 
and scarious scales, spirally and most tightly coiled (with one or 
several turns) around the stems of the supporting plant, which 
at a distance appears as if a rope were twisted round it. The 
flowers are so crowded that many are abortive, and as it were 
strangled, presenting nothing but a bunch of scales ; and others, 
which are apparently perfect, do not mature seed. 
The principal difference between this genus and Cuscuta con- 
sists in the calyx, which is not monosepalons, but is composed of 
numerous imbricated scales; of which the two or five exterior, 
being much smaller, may be Considered ‘as bracts ; while the ten 
inner, which are nearly equal in size and shape, ‘coenliate, and 
with reflexed or squarrose summits, appear to constitute the 
proper calyx. ‘The corolla and stamens, with their scales, are 
entirely similar to the corresponding organs in Cuscuta: so is the 
ovary ; but the unequal styles are generally longer in proportion, 
and the stylopodium is as large as the ovary proper, or even lar- 
* From ies @ scale, and ayxe to strangle: a scaly plant, strangling those on 
which it grows. . ‘
