flower subtended by a secondary innovation, differs also in tbe
tufted habit, the imbricated leaves (which, although only slightly
different in form, have smaller, more ohlorophjdlose cells), but,
above all, in much smaller obtusely 5-carinate perianths, as compared
with the large, deeply plicato-oarinate perianths of Z. Holtii.”
Tiie description and observations are taken from Dr. Spruce’s
communication to the “ Journ. of Bot.” for Feb. 1887.

(1849) (nec J. minutissima, Sm.)
Dioicous, loosely spreading, rarely subcasspitose, often creeping
upon mosses, minute, green. Stems straight, not geniculate,
vaguely branched, subradiculose. Leaves distant or subcontiguous,
erect to erecto-patent (10°-30°), ooohleato-ooncave, rotundo-ovate,
at the apex narrower, obtuse or abruptly acute, from the base
to ^ or f (rarely almost to the apex) obtusely complicato-bilobed,
postical lobe more or less shorter and narrower, rarely almost
equal, turgid at the keel, margin incurved or often plane, apex
apioulato-aoute; cells small, slightly chlorophyllose, subpellucid,
smooth or slightly convex, obscurely tuberoulose, 4-, 5-, and 6-
angled, walls firm, no trigones or thickened angles. Stipules
distant, about 3 times shorter tlian the leaves, rather broader
than the stem, oval, to about -J- or tbe middle, or rarely below
bifid, segments linear-subulate, 2 cells broad below, at the apex
1 cell broad. Female flowers terminal, innovations produced on
one or both sides. Bracts large, 2 to 3 times larger than the
leaves, subdivergent, at an angle of 60°-90°, almost to the middle
bifid, complicate, keel narrow, winged, antical lobe semi-ovate
acute, postical lobe shorter, rarely equally as long, semi-lanoeolate
or obliquely cuneate, margin cellulose-erose, sometimes subden-
ticulate. Bracteole a little shorter, erect oblong or oval-lanceolate,
to about \ acutely bifid, segments acute. Perianth (hardly
mature) immersed in the bracts, pyriform-oblong or obovate,
apex depressed, terete below, towards the apex obtusely 5-angled,
cells slightly convex, papillose or almost smooth.

O bs.—Misled by an original specimen from Sowerby of Jung-
minutissima, Smith, figured in Eng. Bot., Dr. Spruce was under
the impression that it was the same as Jung, ulicina of Taylor,
and therefore reduced Jung, ulicina, Tayl. to a synonym of Jung,
minutissima Sm., and for the fertile Jung, minutissima of Smith
coined the name Lejeunea Taylori, Spruce ; many years afterwards
he found in comparing with the figure in Eng. Bot. of Smith’s
Jung, minutissima that it could never have been drawn from that
