amplexicaul. The substance is, in a s trik in g degree, thick and subearnose, th e cellules
large, o f a roundish figure, b u t by no means regularly o r closely placed (f. 6) ; when dry,
from th e circumstance o f the sh rin k in g o f th e cellules, a curiously pu n c ta ted appearance
is observable even with the naked eye. T h e color is o f a dingy b u t yellowish-green a t the
base o f th e p la n t, gradually a ssuming a purple tin t as th e leaves approach th e extremity
o f th e p lan t, where tliey a re entirely o f th a t color.
Stipules (f. f. 7. 8) though min u te , always p re sent, widely subula te , and, like th e leaf,
composed o f cellules of. a roundish form, and large in proportion to th e size o f th e stipule.
Th e ir color is usually pale green.
Perigonial leaves more concave, and fo r th e most part more crowded th a n th e r e s t ; a t the
base they a re a little swollen, and the ma rgin is there incurved (f. 8).
O f th e Perichælial leaves there is one e rect pair to th e base o f each calyx, to which they are
in a slight degree appressed ; the ir margins are frequently a little waved.

Anthers (f. 9) are situated in the axilla o f each perigonial leaf.

Calyx (f. 10) ovate, o r oblongo-ovate, by no means plicate, cylindrical, except a t th e apex,
where it is compressed, tru n c a te , very obsoletely toothed, and divided into two sh o rt lips.
In color aud texture it closely resembles th e leaves, b u t th e cellules are o f a more oblong
shape.
Calyptra obovate (f. 10), whitish, somewhat membranaceous, re ticu la te , tipped with a sh o rt
tu b u la r style. A few small barren p is tilla surround its base.
Peduncle short, being scarcely th re e times th e len g th o f th e calyx, w hite , cellulose.
Capsule ovate, da rk brown, furrowed longitudinally and transversely, sp litting into four
equal valves (f. 10).
Seeds spherical, fulvous. Spiral filamenls composed o f a double helix, short, ra th e r closely
twisted (f. 1 1 ).
Oes. Upon th e leaves o f this species, a very minute, nearly spherical, blackish, tuberculated
Fungus is frequently to be seen, and I have figured it in th e annexed plate (see f. f. 3 , 4 , 12, 13).
Inte rn a lly , along with a w h itb h mucilage, i t contains a n um b e r o f oblong pellucid bodies, each
with from two to four ovate brownish seeds. A very s imila r parasite, if not) th e same, is
found also on the leaves o f J . scalaris, b u t I am n o t aware th a t th ey have eve r come un d e r the
notice of any write r upon th e subject.
1 have already mentioned, un d e r my description o f J . anomala, th e distinguishing marks
between th a t species and th e p re sen t, and I have little more to add, b u t th a t my own subsequent
observations, as well as those of Mr. Lyell, who has lately h ad th e b e st opportunity o f examining
th e two p lan ts in th e ir native places o f growth, have more and more s trengthened th e opinion th a t
they a re tru ly different. Notwithstanding th e unwearied exertions o f th e able Botanist ju s t
mentioned, th e fnactification o f J . anomala has hitherto eluded his research; b ut, whatever be the
fa te o f th a t p lan t, th e one here described, and named a fte r my friend Dr. Taylor, o f D ublin, will, I
tru s t, be p e rm itted to hold its place in the list o f species, as a m emorial o f th e g re a t assistance which
I have derived from one o f th e most zealous and acute Cryptogamists o f th e present day.
Mr. Lyell observes th a t J . Taylori has an agreeable odor, which resembles th a t a rb in g from
the flowers o f th e Heath.
