907. *L. taxifolium, Sw. ; L. axiUare, Roxb. — A plant much 
resembling a sprig of Norfolk Island Pine, found, very rarely, grow- 
ing amongst the grass on the highest land at Diana’s Peak, alt. 5‘4, 
where it attains a height of four to six inches. 
122. Musci {Mosses). 
The following account has been kindly prepared by Mr. Mitten, 
who has also illustrated four species, Plate 56. 
Those species marked 4 have not been found at St. Helena, hut only at Tristan d Acunha. 
Those species marked $s have been found at Ascension, and not at St. Helena.

908. *D. proscripta, Hornschuch, in Hor. Phys. Berol. p. 60 ; 
{Didymodon), Leptotrichum Hornschuchii, C. Mueller, l.c. p. 450. — 
Gathered by all collectors, and, abundantly in fruit, by Dr. Seemann. 
This species has been well compared by O. Mueller with the 
European Leptotrichum jlexicaule, which, in the aspect of its foliage, 
it much resembles ; but the quadrate base of the leaves, from which 
the subulate portion is suddenly contracted, is very different. 
A considerable number of species, nearly all of a smaller size 
than the present one, is found in various parts of the world. One 
species is known from the Cape of Good Hope, several from India 
and the Islands of the Indian Archipelago, and a few from Hew 
Zealand ; but none have yet been observed in Europe or H. 
America, unless the minute Siligeria recurvcda inhabiting these 
countries should be referred to the same group. One species has been 
described by Dr. Hampe, from the Andes of Bogota ; but none has 
been as yet discovered in the remainder of that immense continent. 
All the species as yet ascribed to this group, are closely similar in 
the form of the capsule, which is that common to the Dicranella! , of 
an oval form, and when passing maturity more or less evidently 
ribbed ; so that it would appear that, although the species are im- 
mediately distinguishable by the curvature of the seta, there is no 
other essential point of difference.
