Surculi about three-quarters of an inch in length, imbricated one over another, creeping, 
flexuose, once or twice irregularly divided into many short, patent blanches, of which 
the fertile ones are somewhat incrassatcd upwards, the rest are filiform throughout. 
Leaves (f. 6.) bifarious and distichous, alternate, auriculated, distantly placed in the 
lower parts of the plant, the rest so closely imbricated as entirely to conceal the upper 
side of the surculus, the cauline ones scarcely exceeding the fifth of a line in diameter, 
those in the fertile shoots becoming rather larger as they approach the calyx: 
they are of an orbicular figure, above slightly convex, varying in color from a deep 
purple hue to an olive-green in more sheltered situations, entirely devoid of gloss, 
furnished at their base with an auricle (f. 4), which generally inclines more to a 
greenish hue, and is in its appearance widely unlike the leaf, in different parts of 
the plant putting on a different appearance (f. 3). In the barren branches this 
auricle is about one-fourth of the size of the leaf, attached to its lower margin, and 
closely appressed to its inner surface, nearly spherical, with an opening beneath, 
whence Micheli has aptly applied to it the term “ cucullatus In the fructifying 
branches the same formation of the auricle is apparent in the lower parts, but in 
proportion as it approaches the extremity, the hollow vesicle gradually unfolds : in 
the fourth pair from the calyx the opening appears wider; in the next above them 
the margins only are remarkably revolute ; in the succeeding pair the margins are 
so far unfolded as to exhibit a lateral tooth, while the uppermost pair, or 
Perichcetial leaves (f. 7) have the auricle an oblong, obtuse, leaf-like appendage, the 
margins still a little revolute, and the exterior furnished with one or sometimes 
two long and sharp teeth ; this auricle is appressed with its inner and convex surface 
to the under side of the calyx, while the leaf, which is here more inclining to ovate 
than in any other part of the plant, has its lower surface applied to the upper side 
of the calyx. The texture of these leaves is exactly similar to that of the rest, com- 
posed of "exceedingly minute roundish cellules , scarcely visible but with a high power 
of the microscope. 
Perigonial leaves, from twenty to thirty or more in number, very closely imbricated, 
upon short branches, rather smaller than the cauline ones, and remarkably concave 
or ventricose: the auricle is about one-third of the size of the leaf, ovate, concave, 
each closely tiled over the one above it. 
Stipules (f. 5) somewhat wider than the stem, one to each pair of leaves, ovate, approaching 
to round, quite plane, cleft at the extremity with rather a deep and acute notch : 
these, likewise, alter their figure as they approach the calyx, becoming larger and 
divided into three or four unequal faciniae, of which in the calycine stipule there are 
five or six (f. 8) . Their texture resembles that of the leaves ; their color, from being 
less exposed to the light and air, partakes less of the purple tint, and generally is of 
a dirty green. 
Mali; Fructification situated in the axilke of the perigonial leaves, upon the short lateral ramuli. 
These perigonial leaves are remarkably closely imbricated, so much so, that the ramulus 
seen from above has very much the appearance of that of J. concinnata, and the whole length
