Perigonial leaves (f. 2 ) no otherwise lUfferent from th e rest, than in being more concave and
more closely appressed or imbricated one over another, so th a t th e extremities o f the
branches, where they a re fourni, are incrassated, which renders them th e more readily
discoverable.
Pericheetial leaves (f. f. 3. 9. 10. 11) seven o r e ig h t in numbe r, increasing in size from the
base o f the fruit-be a ring ramulus, where they scarcely exceed th e common cauline leaves,
to th e insertion o f the calyx, where they are twice o r thric e th e ir le n g th ; imbricated on
every sid e ; the ir figure oblong, approaching to quadrate, concave, or, perhaps, more
correctly speaking, semicyliiulrical (f. f. 9. 10) ; a t the apex, they have a deep and wide
notch, o f wliich the segments are acute and n ot unfrequently divaricated, waved, or
even recurved.
Stipules {f. f. 7. 8) small, scarcely more than one third o f th e size of th e leaf, plane, and
eithe r appressed, or projecting a little from the stem : th e ir form is ovate, and they are
divided a t th e extremity by an acute sinus in to two ra th e r sharp segments, which in len g th
are about equal to one third o f th a t o f the stipule.
M a le F ructii-ication situ a ted in th e axillæ o f the perigonial leaves : Anthers (f. 16) generally
found singly, sometimes two to g e th e r, nearly spherical, o f a pale greenish ash color ; in a young
sta te faintly, a t an advanced period more evidently, marked with reticulations : T h e fo o ts ta lk
white, semipellucid, transversely striated.
Female Fructification te rm ina l upon th e proper footstalks.
Calyx (f, 12) nearly h a lf a line in length, oblong, a little a ttenua ted a t th é base, and
slightly narrowed upwa rd, where it is longitudinally plicated ; th e mouth small, and
evidently toothed. In texture i t resembles the leaves, as it does in color, th o u g h it is
often o f a paler tint.
Calyptra (f. 13) ovate, whitish, delicate, furnished with a sh o rt style. I t opens with a vertical
fi!=sure for th e emission o f th e capsule : its base is surrounded by a few barren pistilla.
Peduncle about four lines long, white , cellulose.
Capsule (f. 14) small, ovate, brown, sp litting into four, equal, ovate valves.
Seeds and spiral Jilaments (f. 15) fulvous; the former spherical ; the la tte r formed o f a
double helix, rather closely twisted.
Gemmæ (f. 4) are found a t th e same season o f the year with the male and female fructification
; th e surculi, a t the naked apex o f which they are produced, have th e ir leaves
smaller and more distantly placed, as we ll as more e rect and appressed, th an is usual with
the fructiferous individuals. T hey a re collected in m in u te , ra th e r compact spherical
masses, so th a t, in this respect, as well as in th e ir situa tion, they resemble those o f
J . hicuspidata and J . Trichomanis. Each particle is pellucid, o f a greenish color, and
angula r (f. 17).
U n t o my clesci iption of J . byssacea, (T,ib. x ii.) I first noticed this p lan t, which I lind some
reason to th in k m ig h t be th e same as th a t which is figured by Schmidel, in his Ica n a , t. 62. 20.
/ . 2 and 1. 64. / . 2. Bu t those representations are too imperfect to enable me to decide w ith any
degree.of c ertainty, and th e im p o rtan t distinguishing character, the bifid stipule, seems to have no
existence there, i have, therefore, considered it best to quote the Schmidclian plant with a mark
o t doubt, and I gladly take th e opportunity of distinguisl.ing the present by Ihe name o f its discoverer
my friend, th e Rev. R . B. Francis, who has so successfully investigated th e vicinity of hi.
own residence in search of th e plants o f th is genus, and hm so kindly and liberally communicate,I
to me numerous specimens, and much valuable information respecting them.
In h ab it, J . Francisci certainly approaches J . byssacea, as well as smali varieties o f .f. bicusp,data ,
b u t the u p rig h t growth o f the surculi, and the more concave and less deeply notched leaves are of
themselves sufficient marks o f discrimination; and when the presence o f th e stipules ts taken into
consideration, no difficulty in distinguishing them wifi be found to occur.
W itli regard to th e stipulated species, among w hich it ranks. I am unable to m ention any to w hich
it beats such a similarity as to render i t necessary to r me here to notice th e points in which they
differ.
