falcati; lobus intermedius valde complicatus, dorso carinatus, extensus late 

 ovatus vel semiorbicularis, apice rotundato mucronatus. Columna parva, 

 crassa, circa 7 mm. longa, arcuata, inpedem gynostemio breviorem extensa. 

 anthera semigloboso-conica, minute papillosa. 



This species has much shorter, broader leaves, longer peduncles and 

 larger labellum than Camaridium pulchrum. Schltr. It is distinguished 

 from C. ochroleucwm Lindl. by its shorter, broader leaves, larger flowers 

 borne on long peduncles, and by the acute lateral lobes of the labellum. 

 From C. Wrightii Schltr. it is differentiated by its larger flowers and by 

 the structure of the labellum.

Erythrodes Killipii, sp. nov. 



Herba alta, terrestris, e rhizomate cauliformi erecta, circa 62.5 cm. alta. 

 Radices paucae, lanuginosae, e nodis exorientes. Caulis glaber, in sicco 

 plus minusve 5 mm. latus, internodiis inferioribus plus minusve 7 cm. 

 longis, superioribus multo brevioribus. Folia in visu septem, oblique 

 lanceolato-elliptica vel ovato-elliptica, usque ad 9.5 cm. longa et 4.2 cm. lata 

 (folium supremum multo minus), in caulis parte superiore approximata, 

 apice subito acuminata, basi in petiolum cuneato-angustata, textura 

 chartacea, nervis tribus prominentibus. Petiolus alatus, basi in vaginam 

 laxe dilatatam tubularem scariosam transeuns. Pedunculus ad racemum 

 circa 18.6 cm. longus, densius pubescens, in sicco angulatus, vaginis quat- 

 tuor laxis scariosis ornatus. Racemus circa 17.5 cm. longus, dense multi- 

 florus, rhachide pubescenti. Bracteae inflorescentiae flores conspicue super- 

 antes, lanceolatae, longe acuminatae, basi cucullatae, trinerviae, omnino 

 glabrae, marginibus inferioribus irregularibus vel erosulis, marginibus supe- 

 rioribus integris, involutis, usque ad 1.9 cm. longae et 6.4 mm. latae (bractea 

 basalis) . Flores in generis mediocres. Sepala petalaque in galeam agglutinata, 

 pubescentia. Sepala oblonga, circa 7 mm. longa et 2.1 mm. lata, acuta, 

 uninervia, basi obliqua. Sepalum dorsale lanceolatum, circa 7 mm. longum 

 et 3.4 mm. latum, obtusum, uninervium, basi cucullatum. Petala cum 

 sepalo imparl arete agglutinata, ligulato-spathulata, sepalis paulo breviora, 

 circa 2.25 mm. lata prope apicem, uninervia, marginibus superioribus 

 minutissime erosis. Labellum in positu naturali arcuato-decurvum, parte 

 apicali deflexa et partis inferioris marginibus valde involutis; lamina 

 expansa ligulata, circa 6 mm. longa, tertia parte apicali leviter constric- 

 ta et subito in laminam latam reniformem circa 4.1 mm. latam, obtuse 

 apiculatam dilatata, pars basalis circa 2.4 mm. lata, callis binis obscuris 

 percurrcntibus. Gynostemium breve, rostello alte et acriter bifido. Cal- 

 car ovoideum, circa 3.5 mm. longum. Ovarium dense glanduloso- 

 pubescens. 



The habit of this species suggests very much the habit of Erythrodes 

 procera (Physurus procerus <Sc/ii!<r, in Fcdde Repert. Beihefte 7 (1920) 73). 

 In E. Killipii the longer floral bracts are entirely glabrous with the margins 

 partly erosulate. In E. procera the floral bracts are one-nerved while in E.
