Dixon: NEW AND RARE AFRICAN MOSSES 75 
Lindbergia pseudoleskeoides Dixon, sp. nov. 
Autoica; gracilis, repens, irregulariter ramosa, ramis inaequal- 
ibus subobtusis, siccitate teretibus, curvatis. Folia caulina laxius- 
cula, ramea dense conferta, madida patentia, sicca erecta appressa, 
late triangulari-ovata, breviter late acuminata, acuta vel subobtusa, 
paullo concava, marginibus planis integerrimis, costa sat valida, 
infra apicem evanida. Cellulae rotundo-ovales, irregulares, parie- 
tibus sat incrassatis, omnino fere laeves, subopacae; alares trans- 
verse elongatae, compressae, permultae, totam basin implentes. 
Folia perichaetialia externa brevia, lata, subobtusa, raptim 
brevipungentia, interna multo longiora, erecta, convoluta, breviter 
rigide acuminata, omnia e cellulis elongatis, linearibus, laevissimis, 
flavo-viridibus instructa. Seta circa 1 cm. alta, pallide rubra, 
theca erecta, cylindrica, pallida, leptodermata, operculo conico, 
obtuso. Peristomium (imperfectum) tenue, flavidum; dentes ex- 
terni dense papillosi, linea media atque articulationes pertenues 
inconspicuae; peristomii interni membrana brevis, dense papillosa. 
Spori 22-23 wu. [Fic. 5.]

Leskea abbreviata Schimp. in all its forms has the leaves with 
longer points, reflexed when dry, so that the branches are less 
julaceous; the branches also are not or very rarely curved when 
dry, the capsule wider, ovate-cylindric, darker and of stouter 
texture, the lid conico-rostellate. The following species is quite 
distinct in habit and leaf-form. 
In habit and leaf-structure the present plant is almost exactly 
like some species of Pseudoleskea, and without fruit its generic 
position would be very difficult to determine. The peristomes in 
the material examined are old and the teeth broken, so that the 
lower part only could be examined. 
Lindbergia haplocladioides Dixon, sp. nov. 
Autoica. Olivacea vel aurantiaca, gracilis; caulis vage repens, 
ramis distantibus, elongatis, tenutbus, subrigidis. Folia madida 
patentia, sicca nonnunquam erecto-appressa, saepissime autem 
apice plus minusve fortiter recurvo; e basi ovata sensim longe anguste 
acuminata, acuta, integerrima; costa fenuts, in summo acumine 
soluta. Cellulae superiores rhomboideae, elongatae, incrassatae, 
in acumine multo angustiores, longiores, alares multae, transverse 
elongatae, compressae; omnes Jaevissimae.
