Perigoriial leaves (f. 2) no otherwise different from the rest, than in being more concave and 
more closely appresscd or imbricated one over another, so that the extremities of the 
branches, where they are found, are incrassated, which renders them the more readily 
discoverable. 
Perichcetial leaves (f. f. 3. 9. 10. 11) seven or eight in number, increasing in size from the 
base of the fruit-bearing ramulus, where they scarcely exceed the common cauline leaves, 
to the insertion of the calyx, where they are twice or thrice their length; imbricated on 
every side; their figure oblong, approaching to quadrate, concave, or, perhaps, more 
correctly speaking, semieylindrical (f. f. 9. 10) ; at the apex, they have a deep and wide 
notch, of which the segments are acute and not unfrequently divaricated, waved, or 
even recurved. 
Stipules (f. f. 7- 8) small, scarcely more than one third of the size of the leaf, plane, and 
either oppressed, or projecting a little from the stem : their form is ovate, and they are 
divided at the extremity by an acute sinus into two rather sharp segments, which in length 
are about equal to one third of that of the stipule. 
Male Fructification situated n the axillae of the perigonial leaves : Anthers (f. 16) generally 
found singly, sometimes two together, nearly spherical, of a pale greenish ash color ; in a young 
state faintly, at an advanced period more evidently, marked with reticulations : The footstalk 
white, semipellucid, transversely striated. 
Female Fructific \tion terminal upon the proper footstalks. 
Calyx (f. 12) nearly half a line in length, oblong, a little attenuated at the base, and 
slightly narrowed upward, where it is longitudinally plicated : the mouth small, and 
evidently toothed. In texture it resembles the leaves, as it does in color, though it is 
often of a paler tint. 
Calyptra (f. 13) ovate, whitish, delicate, furnished with a short style. It opens with a vertical 
fi.-sure for the emission of the capsule: its base is surrounded by a few barren pistilla. 
Peduncle about four lines long, white, cellulose. 
Capsule (f. 14) small, ovate, brown, splitting into four, equal, ovate valves. 
Seeds and spiral filaments (f. 15) fulvous; the former spherical; the latter formed of a 
double helix, rather closely twisted. 
Gemma; (f. 4) are found at the same season of the year with the male and female fructifi- 
cation : the surculi, at the naked apex of which they are produced, have their leaves 
smaller and more distantly placed, as well as more erect and appressed, than is usual with 
the fructiferous individuals. They are collected in minute, rather compact spherical 
masses, so that, in this respect, as well as in their situation, they resemble those of 
J. bicuspidata and J. Trichomanis. Each particle is pellucid, of a greenish color, and 
angular (f. 17).
