amplexicaul. The substance is, in a striking degree, thick and subcarnose, the cellules 
large, of a roundish figure, but by no means regularly or closely placed (f. 6) ; when dry, 
from the circumstance of the shrinking of the cellules, a curiously punctated appearance 
is observable even with the naked eye. The color is of a dingy but yellowish-green at the 
base of the plant, gradually assuming a purple tint as the leaves approach the extremity 
of the plant, where they are entirely of that color. 
Stipules (f. f. 7- 8) though minute, always present, widely subulate, and, like the leaf, 
composed of cellules of a roundish form, and large in proportion to the size of the stipule. 
Their color is usually pale green. 
Perigonial leaves more concave, and for the most part more crowded than the rest; at the 
base they are a little swollen, and the margin is there incurved (f. 8). 
Of the Perichatial leaves there is one erect pair to the base of each calyx, to which they are 
in a slight degree appressed; their margins are frequently a little waved. 
Male Fructification (f. 3) generally near the centre, but sometimes at the extremity of the 
stem : two or three spherical pedunculated 
Anthers (f. 9) are situated in the axilla of each perigonial leaf. 
Female Fructification terminal. 
Calyx (f. 10) ovate, or oblongo-ovate, by no means plicate, cylindrical, except at the apex, 
where it is compressed, truncate, very obsoletely toothed, and divided into two short lips. 
In color and texture it closely resembles the leaves, but the cellules are of a more oblong 
shape. 
Calyptra obovate (f. 10), whitish, somewhat membranaceous, reticulate, tipped with a short 
tubular style. A few small barren pistilla surround its base. 
Peduncle short, being scarcely three times the length of the calyx, white, cellulose. 
Capsule ovate, dark brown, furrowed longitudinally and transversely, splitting into four 
equal valves (f. 10). 
Seeds spherical, fulvous. Spiral filaments composed of a double helixi short, rather closely 
twisted (f. 11). 
Obs. Upon the leaves of this species, a very minute, nearly spherical, blackish, tuberculated 
Fungus is frequently to be seen, and I have figured it in the annexed plate (see f. f. 3, 4, 12, 13). 
Internally, along with a whitish mucilage, it contains a number of oblong pellucid bodies, each 
with from two to four ovate brownish seeds. A very similar parasite, if not' the same, is 
found also on the leaves of J. scalaris, but I am not aware that they have ever come under the 
notice of any writer upon the subject. 
I have already mentioned, under my description of J. anomala, the distinguishing marks 
between that species and the present, and I have little more to add, but that my own subsequent 
observations, as well as those of Mr. Lyell, who has lately had the best opportunity of examining 
t le two plants in their native places of growth, have more and more strengthened the opinion that
