3. D. spinuligera sp. nov.; P. B.-A., No. 2188. Cellulis peri-
centralibus 5, corticatis, cortice glabro, continuo, cellularum minorum,
elongatarum; ramis paucis, elongatis, ramulos breves, patentes,
acutos, gerentibus; apice rainuli junioris fasciculum densum lame
iorum ferente, adultioris nudo; ramellis densissimis, deciduis, mono-
siphoniis, dichotomis, rectis nec divaricatis, cellulis 2-3 diam. longis,
superne 1 diam. modo, diametro ubique aequali; stichidiis conicis
vel cylindro-conicis, prope basin fasciculi ramellorum ortis, tetra
sporangiis 2-4 in verticillo; frondis substantia firma; colore luiro

obscuro. Plate IV, figs. 24-25.

cells; with few elongate branches, bearing patent, acute ramuli, the
younger with a dense fascicle of ramelli at the tip, the older naked;
ramelli very dense, deciduous, monosiphonous, dichotomous, straight,
not divaricate; cells 2-3 diam. long, above only 1 diam.; diameter
the same throughout; stichidia conical or cyclindric-conical, arising
near the base of a fascicle of ramuli; tetrasporangia 2-4 in a whorl.
Substance of the frond firm; color dark red. Type in Collins her-
barium, No. 7243; collected at Shelly Bay, May 4, 1912, Collins.
When ramelli are abundant, this plant somewhat resembles D. punicea,
but the. ramelli show no tendency to a verticillate arrangement, and
fall off more easily. The surface of the frond after the ramelli have
fallen is smooth and even, not knotted and irregular as in D. punicea;
the cells are small and regular, not large and irregular as in that species.
