Thonner, Franz
Angiosperms -- Africa; Plants -- Africa
11. Rostellum with 2 distinct glands, to which the pollen-masses are
attached; side-lobes exceeding the middle-lobe.--Species 110. Southern
and tropical Africa. Some are used as ornamental plants. (Including
_Penthea_ Lindl.) =Disa= Berg
Rostellum with one gland; sides-lobes, if present, not exceeding the
middle-lobe. 12
12. Stigma 2-parted. Rostellum with 3 narrow, subequal lobes.--Species
10. South Africa to Nyasaland. (Under _Disa_ Berg). =Herschelia= Lindl.
Stigma entire. Rostellum more or less hood-shaped, large.--Species 15.
South Africa. (Under _Disa_ Berg). =Monadenia= Lindl.
13. Petals much narrower than the odd sepal, kneed. Lip kidney-shaped.
Stigma not extended in two branches.--Species 1. South Africa (Cape
Colony). (Under _Disa_ Berg). =Forficaria= Lindl.
Petals and sepals subequal. Stigma with 2 erect, linear
branches.--Species 2. South Africa (Cape Colony). =Pachites= Lindl.
14. (2.) Stigma extended into two, usually elongated processes.
[Subtribe HABENARIINAE.] 15
Stigma not extended into processes, rather flat. Column very short. 21
15. Stigmatic processes short, adnate to the lip. Rostellum small,
not prolonged into anther-channels. Column very short.--Species 10.
Tropics. (Under _Habenaria_ L. or _Platanthera_ Rich.) =Peristylus=
Blume
Stigmatic processes free 16
16. Column long, curved. Rostellum not prolonged into anther-channels.
Perianth subglobose.--Species 1. Mascarene Islands. =Acrostylia= Frapp.
Column short 17
17. Rostellum or stigmatic processes 2-cleft. Base of the anther not
enclosed by a channel, but prolonged into solid processes.--Species 7.
Central Africa. (Under =Habenaria= Willd.) =Roeperocharis= Reichb.
Rostellum and stigmatic processes entire, the former prolonged at the
base into two lateral anther-channels. 18
18. Anther reflected. Stigma broad. 19
Anther erect. Stigma more or less slender. 20
19. Middle-lobe of the rostellum exceeding the side-lobes. Lip linear,
entire, with a long spur. Petals broad.--Species 1. Southern West
Africa. (Under _Habenaria_ Willd.) =Barlaea= Reichb. fil.
Middle-lobe of the rostellum equalling the side-lobes. Lip oblong or
broader, usually lobed.--Species 40. Tropical and South-east Africa.
(_Cynosorchis_ Thouars, including _Amphorchis_ Thouars, _Hemiperis_
Frapp., and _Camilleugenia_ Frapp.) =Cynorchis= Thouars
20. Stigmatic processes diverging at a right angle. Spur
short.--Species 1. North-west Africa. (_Tinea_ Biv.) =Neotinea= Reichb.
fil.
Stigmatic processes nearly parallel.--Species 210. (Including _Bonatea_
Willd., _Platycoryne_ Reichb., and _Podandria_ Rolfe). =Habenaria=
Willd.
21. (14.) Glands of the rostellum enclosed in 1-2 pouches proceeding
from the rostellum and persisting when the glands are removed.
[Subtribe SERAPIADINAE.] 22
