PHAIUS. Sepala libera, subaequalia, patentia v. suberecta. Petala sepalis similia nisi angustiora. Labellum 
erectum, concavum v, cucullatum, basi in gibbum cavum v. calcar rectum v. curvulum cum columnae basi continuum 
productum ; lobi laterales ampli, erecti, columnam involventes, apice interdum undulati et cum lobo medio confluentes ; 
lobus medius expansus, saepius brevis latusque, patens v. recurvus, margine saepe undulatus, Columna longiuscula, 
subteres, biangulata v. bialata, apice clavata apoda; clinandrium breve, obliquum, margine sinuatum. Anthera juxta 
marginem clinandrii affixa, opercularis, incumbens, convexa, distincte bilocularis, loculis imperfecte 4-locellatis ; 
pollinia 8, in quoque loculo 4, obovata v. oblonga, a latere parallele compressa, faciebus per paria applicita, paris 
inferioris cujusve loculi quam superiora saepius longiora, apice evidentius attenuata ; omnia in anthera juniore loculos 
fere implente connexa. Capsula oblonga, erostris, costis valde prominentibus. 
Herbae elatiores, terrestres v. epiphyticae, caulibus in caudice confertis, basi saepe in pseudobulbum brevem 
incrassatis. Folia ampla v. elongata, plicata, basi angustata v. in petiolum longum contracta, vaginis saepius striatis. 
Scapi v. pedunculi nunc e caudice oriundi. nunc laterales v. terminales. Flores in racemo plures v. pauci, speciosi, 
pedicellati, flavi, violacei v. albi. Bracteae nunc parvae lineares nunc majusculae, membranaceae v. herbaceae. 
Species ad 15, imprimis Asiaticae tropicae sed ab Africa tropica et insulis Mascarensibus usque ad Australiam,

Limodorum tuberculosum Tuouars Orch. Iles Afr., t. 31. 
Bletia tuberculosa SPRENG., Syst. Veg., III (1826), p. 744. 
@ his beautiful Madagascar species was originally figured by Tuouars, 
4M in 1822, in his Histoire particulitve des Plantes Orchidées recueillies sur les 
oe trois Iles Australes d’ Afrique, de France, de Bourbon et de Madagascar, 
t. 31, as Limodorum tuberculosum. For a long period nothing further seems to 
have been known about it, though SpreNGeL transferred it to Bletia, and Blume 
to Phaius, the latter placing it in a distinct subgenus on account of the absence 
of a spur to the lip. In September 1862 Dr MLLER met with it in woods about 
40 miles from Tamatave and five from the sea, and secured dried specimens, 
besides making a water-colour sketch, and since then it has been collected by 
Hitpepranpt in South Betsileo-land, and the Rev. R. Baron in Central Mada- 
gascar.
