characteristic A neistrorhynchus rostellum and the general 
structure of the flower is quite unlike that of Cyrtorchis. 
A. refractus is very close to, if not identical with, 4. 
laviflorus Mansf., from which it differs in the longer and 
narrower lip with the base widened to form rather ob- 
scure side-lobes, and in the shape of the spur. This tapers 
gradually from the mouth to the narrowest part whereas 
in A. laviflorus it tapers very little until it is suddenly 
contracted to a narrow neck just below the apical swell- 
ing. It still remains doubtful if these differences are 
really specific.

12. Ancistrorhynchus Straussii Schlechter in Beih. 
Bot. Centralbl. 86, Abt. 2 (1918) 139. 
Angraecum Straussii Schlechter in Engler Bot. Jahrb.

Cephalangraecum Straussii Summerhayes in Hutch- 
inson & Dalziel Fl. West Trop. Afr. 2 (1986) 462. 
Easily recognisable by the narrow and relatively short 
leaves and the small flowers, the perianth members being 
less than 2.5 mm. long. In column structure the species 
agrees with the other members of the genus.

In addition to and evidently quite distinct from the 
above twelve species is a fruiting gathering (Mann 2123) 
from 5000 ft. altitude on the Cameroons Mountain doubt- 
fully referred to 4. Metteniae (KXraenzl.) Summerh. (sub 
Listrostachys Braunti Dur. & Schinz) by Rolfe in the 
Flora of Tropical Africa (vol. 7, p. 167). This has short 
strap-shaped leaves with slightly unequal rounded apices 
which are very finely denticulate-serrate.
