Gemmae copiose laete virides magnae ad 300 mu. latae, orbiculares, 
lenticuliformes, in calicibus terminalibus aggretatae. 
Habit. — Siccis tumulis. Umkomaas ; Waterval ; Pretoria. 
This interesting moss differs from Oedipodium Griffithianum, chiefly in 
the shorter stature, the leaves sHghtly smaller with smaller areolation, 
midrib excurrent in strong mucro and leaf base wide without fringe of 
hairs or cilia. The gemmae are never axillary, but always in terminal 
cups, and the gemmae are found on nearly every plant. 
Trematodon afeicanus. Wager and Dixon. (Plate I. G.) 
Herbae cristatae subflavae virides ; caulis erectus circa 10-15 mm. 
altus vix ramosus, folia dispersa erecta interdum flexa angusta lanceolata, 
fastigato subulato apice nervo distincto angusto vix ad apicem product©, 
margine integro vel ad apicem indistincte denticulato, cellulis plus minusve 
rectangularibus a basi laxis ab apice et margine magis densis. Perichae- 
tialia vix dissimilia foliis caulis. Pedunculus 12-18 mm. longus flavus. 
Theca arcuata, cervice plerumque longiore quam theca ipsa sensim in 
pedunculum fastigata, valde strumosa flava cylindrica, paulum flexa, 
operculo rostro longo obliquo ; peristomium dentibus 16 a basi paululum 
conjunctis, irregulariter perforatis vel divisis. Sporis magnis asperis, 
circa 20 mu. diametro. 
Habit. — Humido solo argillaceo, semper in ripis fluvii. Natal and 
Tzaneen, Transvaal. 
This moss appears to be closely allied to T. torile, but it is more straw- 
coloured, of a much greater stature, the struma is more pronounced with 
a longer neck, and the peristome is longer. 
Weisia (Gymnostomum) gracilis. Wager and Dixon. (Plate II. A.) 
Herbae cristatae pallide virides. Caulis brevis sine ramis. Folia 
patentia sicca crispissima sed vix contorta, parva, circa 2 mm. longa, basi 
latiore amplexa et ad apicem obtusum fastigata, margine integro a parte 
superiore paululum papilloso, nervo robusto infra apicem evanido, cellulis 
minoribus, 10-12 mu. longis plus minusve quadratis opacis et paulo 
rectangularioribus, sine papillis. Perichaetialia paulo longiora et obtusiora. 
Theca erecta, symmetrica, subglobosa subrubri-fusca sine peristomio, ore 
lato, operculo conico rostro longiore et paululum obliquo facile decidente. 
Pedunculus subrubri-fuscus plerumque contortus saepe sinosus. Sporis 
regularibus circa 20 mu. diametro. 
Habit. — Tumilis humidis argillaceisque. 
This moss appears to be distinguished by the cells being nearly 
uniform to base, the long seta and short gymnostomus capsule with wide 
mouth.
