The description of Dr. Taylor’s P. ophisthotona seems to coiTcspond so well with the present species, that it
may be easily supposed that it is but oue of those instances in which Dr. Taylor imposed a name of his own on an
already described species; but as no specimens so marked by him are in British herbaria, it is impossible to be
certain if this reference is con-ect. The form distiuguished as var. ß differs in having its leaves everywhere entire;
iu every other respect they agi'ee with those of the denticulate state. The areolation of the leaves is remarkably
minute for the size of the plant.

These specimeus are a little larger than those from New Zealand, but have the same habit, and tbe leaves a
little more directed towards the ventral side. The figure of the perianth in the plate above quoted represents it
much too short; in another New Zeaiaud specimen since received, the mature perianth coincides in shape with that
of P. incurvicolla, represented iu the same plate, fig. 2.

The specimens marked P. axukata by Dr. Taylor in Herb. Hooker, are precisely the common state of P. fasciculata,
but amongst the specimens distributed under tbe name of P. aculeata, some have been found to belong to
P. Stephensoniana, a species not yet received from Tasmania. P. uncialis, to which Dr. Taylor compared his
P. ac«/ea/a, is a species belonging to the same group P. fasciculata and. P.spinulosa. In Ci'j'pt. Antarct. t. 156.
f. 7, the leaves are represented with teeth on the dorsal margin, which does not appear to be commonly the case,
however it might have been in the specimen from which the figure was drawn; the teeth too on the ventral side
are represented too numerous.

Chiloscyphus amphibolius, Nees ab E., gathered iu Brazil by Dr. You Martins, is a smaller species, and has
leaves of a thinner texture than any of the specimens here referred to the Plagiochila chiloscyphoidea of Lindenberg,
a plant which possesses all the characters attributed to Leioscyphus, having the habit of Lophocolea or adloscyphus,
and the perianth of Plagiochila. Besides the three species which Dr. Taylor made of this plant, it composed part
of his Lophocoleapallide-virens, probably all that part regarded by him as “ (status minor) omnhio fuscati,” for the
specimens are all of a brown colour, uot obseiwable in the Lophocolea itself. The bulk of tbe specimens of Lophocolea
multipenna undoubtedly belong to tbe present species; but creeping over it in very small quantity is a perfectly
distinct species of Lophocolea, wlricli seems to have furnished part of the characters designating L. multipenna,
particidarly the triquetrous perianth ; but the form of the leaves, “ obovatis ” and “ ovato-oblonga,” relates alone to
a rather smaller thau usual state of Leioscyphus chiloscyphoideus, and specimens exactly similar were gathered at
Cape Horn. To this genus belongs L. æqualus, Flor. Antarct. p. 433.1 .158. f. 3, L. strongylophyllus, 1. c. t. 62. f, 9,
L. reclinans, 1. c. t. 159. f. 1, of which the perfect pei-ianlh is nearly three times longer than broad, compressed,
the mouth truncate aud smooth; about half au imperfect perianth is represented in the figure 4. In L. turgescens,
1. c, t. 64. f. 2, the perianth is compressed, the mouth wide, and the lips smootli ; but it presents slight indications
of being formed of tliree parts, namely the two uppermost leaves and amphigastrium, for there are often two notches
in the mouth, just where the line of union must be supposed to be.
