" Caulis cum innovationibus 5 mm. altus cum foliis ubi in comam aggregatis 

 humidis 1 mm. angustior, pallidus. Folia inferiora 0'52 mm., superiora 1 mm. vix 

 attingentia pallide viridia. Pedunculus 4 mm. longus. Theca cum operculo 

 150 mm. 



" Both these mosses correspond in size and appearance with the Hymenostylium 

 viridulum (Gymnostomum, auct. plur.), and are therefore considerably less than the 

 European A. compactum, which may be taken as the type of what may become an 

 extensive group of species, all agreeing very nearly with the oldest known species, but 

 which, when carefully compared, show a number of small differences which preclude 

 the probability of their being varieties ; in all the position of the inflorescence, as well 

 as the form of the floral leaves, is very uniform, and of itself indicates the generic 

 place of specimens destitute of fructification, and by this means species are known to 

 exist in Java and also in Japan. 



" To return to Anoectangium Mariei, the description of which is good, only, in that 

 part relating to the male flowers, it is omitted that they are apical, a condition which 

 at once precludes the consideration of the species being referable to Anoectangium, 

 and by the habit, as also by the form of the foliage and the papillose nerve, it comes 

 near to Trichostomum indicum and some other species, forming a not very well 

 defined group standing in the Musci Austro Americani under Bridel's name 

 Plaubelia. 



" Before Lorentz left Europe he contributed a small specimen of what he had 

 described in his Pugillus spec. nov. Exot. 160, as Pottia (Hyophila) Roscheri, which 

 had been gathered by Roscher in Zanzibar. This was entirely barren, and the de- 

 scription merely contrasts it with Hyophila spathulata, a moss to which in fact it 

 has no near resemblance ; and is thus so misleading, that without his specimen its 

 identification with the moss gathered by M. Marie by description alone would have 

 been beyond possibility. By right of priority the name of the species must be 

 ' Roscheri,' but its generic place is not so easily settled. During Dr Bayley Balfour's 

 visit to the island of Mauritius he gathered a few fertile stems, from which it is seen 

 that the fructification is in all respects similar to that of Trichostomum indicum,, 

 from which T. Roscheri differs in being a little more robust, and some other small 

 particulars, but it is alike remote from both Anoectangium and Hyophila when 

 compared with H. spathulata."
