Broth. MS. in litt. ad Rev. С. Н. Binstead.) (Pl. 27. fig. 17.) 
Dioieum videtur. Sat robustum, dense cæspitosum, ochraceum, circa 
3 em. altum, nitidiusculum, ramosum, apice faleatum. Folia sat conferta, 
regulariter secunda, sepe pulchre faleato-secunda, 2 mm. longa, pallida, e basi 
ovato-lanceolata anguste longe convolutacea subulato-acuminata, acuta, integra 
vel apice subdenticulata, enervia, supra ob cellularum parietes prominentes 
sepe indistincte subrugulosa. Areolatio normalis, ad infimam basin sæpe 
lutea ; cellule alares hyaline, magne, vesiculares, sat tenere. Perichætium 
parvum, bracteis e basi late ovata raptim т acumen cquilongum bast eroso- 
dentatum contractis. Seta tenella, 1°25 сш. alta, levis vel ad apicem 
indistincte rugulosa ; theca minuta, subpendula, collo abrupto paullo tuber-

Hab. Matang, Sarawak, St. V. B. Down, 1899, ex herb. Binstead. 
This was determined by Brotherus as 7richosteleum Down, п. sp., but it 
appears to me to be a Sematophyllum. It is near to an unpublished species 
“ Acroporium falcatulum, Fleisch., No. 492 M. Frond. Archip. Ind.,” from 
West Java (nee Sematophyllum faleatulum, Broth. in Hedw. Bd. 50, p. 144), 
but that is a more slender, less cæspitose plant, with the upper cells 
apparently quite smooth, and a somewhat different form and structure of 
the leaf-base. S. faleifolium, Fleisch. ined., has a quite different habit and 
branching, shorter leaf-points and different fruit. 
I have found no d flowers or plants, and though the specimen is richly 
fruiting, I believe it to be dioicous. 
S. PALANENSE (Hampe), Broth. Decayed wood in jungle, Sandakan, c.fr. 
(Nos. 52, 54 в, 58). There are no specimens of the Bornean S. palanense in 
Hampe’s herbarium, but the description fits the above plants admirably. 
PILŒCIUM PSEUDO-RUFESCENS (Hampe), C. Muell. Tree in jungle, San- 
dakan (No. 56). 
RHYNCHOSTEGIUM vAGANs (Harv.), Jaeg. Rotting wood below waterfall, 
Sapong, near Tenom (No. 207). Not hitherto recorded, I believe, from 
Borneo. It agrees quite well with the Indian plant, which extends eastward 
фо Java, Ceram, and Ternate.
