Dixon: NEW AND RARE AFRICAN MOSSES 65 
Campylopus (Eu-cAmMpyLopus § TRICHOPHYLLI) angolensis 
Machado & Dixon, sp. nov. 
Sat robustus; caules circa 4 cm. alti, interdum furcati, densi- 
folit, superne olivacei, infra fusci, per totam fere longitudinem 
dense rufo-tomentosi, haud intertexti, facile separabiles. Folia 
valde conferta, sicca suberecta, madida patentia, 5-7 mm. longa, 
0.75-I mm. lata, e basi oblonga parum concava cito angustata, mar- 
ginibus superioribus convolutis, serrulatis; inferiora in pilum breve 
fuscum subintegrum desinentia, superiors pilo longo flexuoso flavido 
denticulato aristata. Costa infra 2-3 folii latitudinem occupans, 
optime limitata; sectione eae C. flexuosi Brid. sat similis. Areolatio 
superior breviter rhomboidea, cellulae supra-alares latae, rectangu- 
lares, marginem versus minime angustatae, alares magnae, 
rubellae, auriculas inflatas pernotatas instruentes. 
Flores aggregati, comosi; setae aggregatae; theca leniter asym- 
metrica, basi parum strumosa; calyptra fimbriata. 
HABITAT: Gambos, Angola, on the ground at 1,250 m. alt., 
April, 1915, Juliano de Carvalho, communicated by Dr. Ant. 
Machado. 
I do not know any species from Central or South Africa nearly 
resembling this; nearly all the Angola species as well as those 
from British East Africa have a very wide nerve. In the present 
plant the leaf base is almost exactly identical with that of C. 
flexuosus Brid., as is also the nerve section and areolation generally ; 
the hair-point, which at once distinguishes it from that species, is 
notable in not being hyaline, but yellowish or, in the older leaves, 
brown, similarly to what obtains in some forms of C. imtroflexus 
(Hedw.) Mitt., from which however the plant is entirely distinct. 
C. ethiops Welw. & Dub. differs in the black color, entire leaf 
Margin, etc.

This agrees exactly with the description by C. Miiller of 
Wilms’s plant (Transvaal, L. Chriss). Wilms’s specimens were, 
however, sterile, while Wager’s are fruiting, with mature, de- 
operculate fruit. The terminal seta is short, 1.5-2.5 mm. in length; 
while the capsule is erect, quite symmetrical, and constricted be- 
low the mouth when dry, so as to be markedly urceolate.
