2. Disa secunda. Swartz l. c. Thunb. Fl. Cap. 14. 
D. foliis radicalibus brevibus ensiformibus erectis, caule nudo distanter 
vaginato, floribus distantibus secundis, sepalis oblongis æqualibus infra 
apicem mucronatis, galeà conformi infra medium dorsi saccatá, petalis 
oblongis acutis, labello filiformi sepalis dupló breviore.

Satyrium secundum. Thunb. Prodr. 4. 
Hab. ad Cap. B. Spei; prope Fransche Hoek, Thunberg; in Dutoits- 
bergen, et Draakensteensbergen, Drege. (hab. s. sp.) 
Flowers large, purple, from 4 to 7 on a scape about 2 feet high. It 
varies with narrower leaves, and sepals. 
8. Disa crassicornis. 
D. caule folioso, foliis ovato-oblongis acutis erectis superioribus minoribus, 
spicà rarà pauciflorà, sepalis lateralibus oblongis sub apice mucronatis, 
galeà minore longe infundibulari arcuato horizontali, petalis reflexis 
labelloque lanceolatis. 
Hab. ad Cap. B. Spei, in summo monte Witbergen, Drege. (hab. s. sp.) 
Vix pedalis, scapo foliis obtecto. Spica in exempl. nostro 4-flora. Galea 
cum calcare bipollicaris. Stigma latum margine superiore crenato, 
disco radiis tribus elevatis carnosis auctum. Anthera linearis, erecta, 
stipitata, rostello brevi, utrinque cucullo lacero aucto.  Pollinia haud 
vidi; si his cucullis glandule includuntur genus erit Disà diversum, 
cui nomen PacuycEna idoneum videtur. 
$ 2. Micrantha. 
4. Disa incarnata. 
D. caule basi vaginato sursum folioso, foliis linearibus caulinis latioribus 
appressis acutis vaginantibus, spicà ovatà, bracteis oblongis acutis 
florum longitudine, sepalis oblongis obtusis, galeà convex4 obtusa 
medio calcare pendulo clavato ipsà longiore auctá, petalis orbiculatis 
dimidiatis galee appressis marginibus contiguis rectis rostratis, labello 
filiformi sepalis breviore. 
Hab. in Madagascar, Lyall. (hab. s. sp. comm. cel. Hooker.) 
Caulis pedalis, floridus vaginatus, sterilis foliosus. Spica pyramidalis, 
bipollicaris. 
5. Disa gracilis. 
D. caule basi folioso sursum vaginato, foliis ensiformibus erectis, vaginis 
laxis acutis, spicà gracili multiflorà, bracteis oblongis acutis florum 
longitudine, sepalis oblongis obtusis coriaceis, gale infra medium in 
calcar carnosum inflatum pendulum ovario brevius productà, petalis 
obovatis emarginatis membranaceis, labello lineari. 
Hab. ad Cap. B. Spei ; in Langekloof, Drege. (hab. s. sp.) 
This plant has much the appearance of a Monadenia ; its stem 15 two 
feet high, with a slender spike; the expansion of the flowers JS about 
$ an inch. D. physodes of Thunberg, which I have never seen, seems 
from the description to be nearly allied to it. Perhaps this is only à 
starved state of Disa chrysostachya ; Mr. Drége sent both under the same 
number.
