calyx, often on the corolla, and rarely on the filaments or style. 
Brown is of opinion that the two glands, or rather bladders, of 
which a stomate is composed, are each analogous to the single 
bladders found occupying the inner face of the meshes of the 
cuticle. 
The surface of the cuticle is either smooth or furnished with 
numerous processes or appendages, which originate either from 
the cuticle or the cellular substance beneath it, and are entirely 
independent of the vascular and ligneous systems; these are, 
hairs , scurjiness, glands , and prickles. Hairs are minute 
transparent cellular bodies, formed either of a single cell of 
tissue or of several placed endways in a single series; they are 
not found on true roots, except at the time of germination, nor 
upon any parts of the stem that are formed under ground or 
that grow under water. They are of two kinds, namely, 
lymphatic and secreting; the former taper gradually from the 
base to the apex, the latter are visibly distended into recep¬ 
tacles of fluid. The various parts of plants, when clothed or 
furnished with hairs, are described as being downy, pilose, 
villose, tomentose, ciliated, bristled, stinging, hispid, silky, 
arachnoid, rough, bearded, and stellate, to which might be 
added other terms, chiefly modifications of the above. Scurfi- 
ness is of two kinds: scurf\ properly so called, is the small, 
roundish, flattened particles which give a leprous appearance to 
the surface of plants ; ramentce are thin brown foliaceous scales, 
sometimes abounding on young shoots, especially the backs of 
the leaves of ferns: both of these consist of thin flat mem¬ 
branous processes, formed of cellular tissue springing from the 
cuticle. Glands are small collections of firm cellular tissue, 
formed for the purpose of secreting the juices of the plant; they 
are known by the terms stalked, sessile, and lenticular glands, 
papillae, &c. Prickles are rigid opaque processes, formed of 
cellular tissue, and terminating in a point, which becomes in¬ 
durated. They have no connexion with woody tissue, by which 
character they are obviously distinguished from spines. They 
are found on all parts of plants except the stipules and the 
stamens; rarely on the corolla: their most common position is 
on the stem and the petiole of the leaf.
