27. Nitophyllum punctatum, Grev. (Fucus punctatus, Turn, 
t. 71.) 
George Town, V. D. L., R. Gunn, Esq., n. 1270 (with 
capsules), and n. 1269, 1271 (with granular fruit). 
28. Nitophyllum, n. sp.1 
George Town, V. D. L., R. Gunn, Esq., n. 1273 and 1276? 
—The specimens are without fruit, and therefore I do not 
venture to found a species upon them in a genus liable to such 
variations of form. It so closely resembles, in the dichotonous 
linear frond, bordered with ciliee, some states of Rliodomenia 
bifida, that I at first regarded it as that species; but the reti¬ 
culation of the frond are very much larger, and evidently point 
to a place in Nitophyllum. —Mr. Gunn’s n. 1282, is also a 
Nitophyllum in a young state, and probably new. 
29. Nitophyllum affine, Harv.; caule brevi, carnoso, mox in 
fronde latissimf: flabelliformi, lacerati, enervosfl, membranaceti, 
basi subopacfi crassa expanso; segmentis subpinnatifidis, sinu- 
bus rotundatis, soris granularutn oblongis in segmentis ultimis 
longitudinaliter ordinatis. 
George Town, V. D. L., R. Gunn, Esq., n. 1272.—Nearly 
related to N. Gmelini, and strongly resembling the large Irish 
state of that plant, but differing in the position of the sori. 
It rises with an evident stem which soon expands into the 
cuneate dark-coloured base of a flabellate membranous frond, 
5 inches long and 7 inches wide, veinless, except for the fused 
indication of the stem at the base, thin and delicate, but pro¬ 
bably crisp in a recent state, and only imperfectly adhering 
to paper. It is deeply inciso-lacerate, or many lobed, the 
segments coarsely sinuato-dentate or subpinnatifid ; the marginal 
lobes blunt and shallow. Sori minute, oblong or linear, ranged 
in longitudinal rows across the tips of the segments, or scattered 
over them;—in our specimen past their prime.
