edge of the lip, and directing itself inwards horizontally 
with an uneven outline, at last touches in front of the: 
column and presents the appearance of a junction. 
C. Trulla (Lindl. in Bot. Reg. 1840. misc. 176. 1841. t. 
34.) ; sepalis petalisque patentibus ovalibus planis, labello: 
latě ovato acuminato obtuso subcordato concavo fimbriato 
apice levi, columnä brevi.—— Tropical America.—— 
Flowers green, unspotted ; lip of the same colour, but 
whitish near the base, with a deep brown spot in the 
middle. 
C. callosum (Lindl. in Bot. Reg. 1840. mise. 183. 1841. 
t. 5. f. 1.); petalis concoloribus lineari-lanceolatis sepalo 
dorsali conformi suppositis, labello ovato-oblongo obtuso: 
basin versus saccato supra saceum callo magno (auran- 
tiaco) instructo margine obsoleté crenato, column 
acuminate cirrhis vix ultra callum extensis. La 
Guayra.—— Exactly like Catasetum tridentatum, var. 
floribundum in habit, but its flowers are different. The 
sepals and petals are of a dull reddish brown, without: 
spots; the column is of the same colour, which may 
perhaps be best compared to that of old spoilt port wine. 
The lip is green, flat, with a yellow tubercle near the 
base above the hollow, and a stain of the same colour 
near the apex. 
C. poriferum (Lindl. in Bot. Reg. 1858. misc. 164.) ; 
labello plano cordato-ovato truncato crenato, lobo apicis 
elevato carnoso ovato medio nectarifero, dente baseos 
ovato incurvo, columnä cirrhosà. Demerara. 
Similar in appearance to C. deltoideum, like which its 
flowers are richly spotted with deep purple broken fascie, 
closely arranged upon a clear green ground. The lip is 
dull green, nearly flat, deeply cordate, truncate at the 
apex, with an obscurely crenated margin. At its base is 
an elevated yellow-tipped broad tooth, and at its apex an ' 
ovate yellow fleshy raised lobe, with a pore in the middle 
secreting honey. 
99. C. deltoideum (Lindl. Bot. Reg. 184 . misc. 157. Myan- 
thus deltoideus Bot. Reg. t. 1896.); labello imberbi sagit- 
tato triangulari, angulis posticis rotundatis dentatis apice 
dilatato calloso margine recurvo basi tuberculato. 
Demerara.—— Flowers deep green, spotted with purple. 
Lip purple, flat, fleshy, with a dash of green in the
