302 BRYOPHYTA OF S. RHODESIA. 



obtusum (Lindb.). Caulis circa Icm. altus, inferne fastigiate 

 divisus, tenellus, filiformis, siccus madidusquemaxime julaceus, 

 teres, apice obtuso; folia densissime julaceo-imbricata, e basi 

 latissima amplexicauli circularia, perconcava, integerrima; costa 

 tenella, ubique aequalis, longe infra apicem terminata, Cellulae 

 ubique, nisi marginales, subaequales, quadratae, magnae. 15/j, ad 

 20/a latae, perchlorophyllosae, parietibus tenuibus, firm is ; margin- 

 alibus seriebus I-" saepe angustiores, rectangulares, saepius 

 echlorophyllosae, hyalinae. 



Dioica. o* planta sola visa. Flos cf apicalis (cito tamen 

 propter innovationemsingulam lateralis visus), conspicuus, brac- 

 teiis perigonialibus pallidis, ovatis, longe acuminatis aristatisque 

 subfalcatis, antheridia pauca, parva includentibus. Cetera 

 ignota. 



Habitat: On flat rocks, Zimbabwe, alt. 3,000 feet (Sim, 

 8747); on granite, Matopos, alt, 5,000 feet (Sim, 8772, 8850); 

 Khami, alt, 5,000 feet (Sim, 8838). 



A remarkable moss, closely related to the equally peculiar 

 A. julacea Hook., but that has crenulate-denticulate leaves, a 

 much wider nerve, and very different upper cells. The cf flowers 

 are very conspicuous, the bracts being much larger and longer 

 than the stem-leaves, 



The resemblance to some species of the genus Gymnomitrium 

 of Hepaticae is very striking. 



Dicranella subsubidata Hampe. — Inyanga, on wet earth, 

 with Polytrichum commune, alt, 6,000 feet, (Dr. Nobbs, 1361, 

 in herb. Eyles). 



General distribution: Cape Province, Natal, Transvaal. 



Leucoloma chrysobasilare (CM.) Jaeg. Syn. Leucoloma 

 woodii Rehm. and MacLea in sched. (Rehm. "M. Austr.-Afr.," 

 No. 444). 



In wet forest, Inyanga, alt. 6,000 feet (Henkel. 2624, 2635b 

 in herb. Eyles). Further records are: Woodbush, Transvaal, 

 Rehmann (original of L. u-oodii (st.); and from the same locality, 

 J. Hewitt, 1910. No. 2, herb. Dixon, c.fr. Usagara Mts. 

 Hannington, and Usagara Mts. Last both ex herb. Mitten; these 

 latter sterile. 



General distribution: Comores, Mascarenes, Madagascar, 

 East tropical Africa, South Africa. 



The two specimens from Mitten's herbarium were determined 

 by him as /. chrysobasilare, and I quite concur with his identi- 

 fication of them with the Anjouan moss. L. woodii is precisely 

 the same thing. 



The fruit (first described by Wager in "Trans. Roy. Soc. S. 

 Afr." IV, 2) is turgidly elliptical, on a very short seta rather 

 less than its own length, so that the capsule is hardly exserted; 

 it is in fact very similar to that of L. bifid urn Brid. 



Leucoloma rehmanii (CM.) Rehm. — Invanga, alt, 6,000 feet, 

 in wet forest (Henkel, 2623b, 2635 in herb. Eyles), the latter cum 

 setis.
