MALAXIS PURPUREIFLORA Ames and Quis. sp. nov. Plate 1, fig. 9; Plate 2, figs* i 
to 8; Plate 7. 
Radices numerosae, fibrosae. Herba terrestris, prope basim 
foliosa, circiter 25 cm alta. Caulis brevis, crassus, 3.5 ad 5 
cm longus, vaginis tubuliformibus inflatis membranaceis imbri- 
cantibus omnino obtectus. Folia 3 ad 8; lamina lanceolato- 
elliptica ad late elliptica, acuminata, acuta, 7 ad 20 cm longa, 
2.5 ad 8 cm lata, nervosa, paulatim in petiolum latum basi dila- 
tatum vaginantem transiens. Pedunculus gracilis, cum racemo 
45 ad 46 cm longus. Bractei scariosae, triangulari-lanceolatae, 
acutae, 4 ad 6 mm longae. Flores juveniles approximati ut 
videtur, sed tardius remotiores. Sepala petalaque margin© 
valde revoluta. Sepala lateralia suborbicularia, apice late ro~ 
tundata, circiter 4 mm longa, 3.2 mm lata, 4- ad 5-nervia. S’e- 
palum dorsale oblongo-ellipticum, obtusum, circiter 5.4 mm 
longum, 2.4 mm latum, 3- ad 5-nervium. Petala anguste oblongo- 
elliptica, obtusa, 4.75 ad 5 mm longa, 1.4 ad 1.7 mm lata, 3- 
nervia. Labellum in circuitu suborbiculare, valde auriculatum, 
circiter 6 mm longum, 5.5 ad 6 mm latum, antice acute pluriden- 
tatum cum callo semicirculari lobulato circa gynostemium 
ornatum, postice in auriculae triangulari-ovatas retrorsas ob- 
tusas extensum. Gynostemium per breve, bialatum. Anthera 
oblata. Pollinia 4, pyriformia, per paria cohaerentia. 
Roots numerous, fibrous. Terrestrial herb, about 25 cm tall, 
leafy at the base. Stems short, stout, 3.5 to 5 cm long, con¬ 
cealed by the swollen, infundibuliform membranaceous leaf- 
sheaths. Leaves 3 to 8, with petioles imbricating below; lamina 
lanceolate-elliptic to very broadly elliptic, acuminate, acute, 7 
to 20 cm long, 2.5 to 8 cm wide, 5-nerved. Peduncles slender, 
including the racemes 45 to 46 cm long, provided with triangu¬ 
lar-lanceolate, acute, scarious bracts, 4 to 6 mm long. The buds 
and young flowers at the apex of the racemes crowded, older 
flowers remote. Sepals and petals with strongly revolute mar¬ 
gins. Lateral sepals suborbicular, broadly rounded at the apex, 
about 4 mm long, 3.2 mm wide, 4- to 5-nerved. Dorsal sepal

5-nerved. Petals narrowly oblong-elliptic, obtuse, 4.75 to 5 mm
