74 Drxon: NEW AND RARE AFRICAN MOSSES 
Hasirat: in Cape Town, on trees, 1910, H. A. Wager 5. 
This distinct species seems best placed in a new section, char- _ Z 
acterized by the somewhat robust habit, entire leaves, gymmo- 
stomous capsules with plano-convex, scarcely apiculate lid. It is 
very near the species of the section Pseudo-ischyrodon Broth., but 
they have a peristome and an apiculate lid. Ischyrodon leptocladus 
Rehm. (Muse. austr.-afr. 633) which, I believe, is.an undescribed _ 
species is very near it (though more robust and with longer 
pointed leaves) and may belong to this section. Although labelled 
‘‘c, fr.” there are no capsules to be found on the specimens either 
at Kew or the British Museum. 
I have been unable to find male flowers, though the plants are 2 
in abundant fruit, and I think it is certainly dioicous. 
LINDBERGIA 
The genus Lindbergia Kindb. (Fabroleskea Best), founded on 
-Pterogonium brachypterum Mitt., has been extended by Brotherus — 
to include some half dozen other species, mostly formerly placed in 
Leskea, one (L. Austini [Sull.] Broth.) being from North America, 
two from China, one from the Himalayas, and one from Abyssinia.

The genus is almost or entirely based on peristome characters, the 
processes of the inner peristome being wanting, and the endostome 
reduced to a very low basal membrane; the outer teeth are usually _ 
also densely papillose, with rather weak lamellae, and the spores 
are large. 
The only African species hitherto known is L. abbreviata : 
(Schimp.) Broth. (Leskea abbreviata Schimp.). It is interesting — 
therefore to find two distinct new species in South Africa. The 
resemblance of the vegetative characters in the one case to Pseudo- 
leskea and in the other to Haplocladium—both genera occurring 
in the same localities with them—is rather remarkable, and 1 
have based the specific names on these resemblances. The fruit, 
however, serves as a ready method of distinguishing them, the — 
capsules in Lindbergia being erect and symmetrical, whereas both — 
in Pseudoleskea and Haplocladium they are inclined, somewhat : 
asymmetrical and curved, with a much better developed inner ‘ 
peristome.
