 Rchb. ni. Bonpl. III. 218: 

 Flore Calaseti callosi, labello tamen minuto conico saccato ante Lasin 



ulrinque revoluto, hmbo inaequahter quinqiiedentato; ima basi utrinqiie 



antrorsum unicornuto. 



Blutlienliulle rothbraun mil Slich ins Olivengrune. Lippe Vs Zoll lang, weiss, pur- 

 purn gesaumt; am Grunde und innerseits auf den obern Zalinen fein purpurn qufr- 

 streifig. Auch die zwei kleineren, nach vorn gerichteten Hornchen am Grunde der 

 Lippe purpurn bandirt. Wir erhielten diese kleine Curiosital gleichzeitig mit dem 

 Hrn. Autor und erkannten sie ebeufalls als neu. Sollte sie — worauf man bei fast 

 jedera Catasetura gefassl sein muss — eine Form einer bekannlen Art sein. so 

 koiinte sie sirh als Hemmungsbildung mit kappiger Lippe des Calasclum trilidum 

 Hook. (}]ijanthus cermius Bot. Reg. 1121) erweisen. Die Lippe hat ahnliche Elemente, 

 Von Hrn. v. Warscewicz 1853 eingesendet. 



25. CATASETUM NASO Liudl. Bot. Reg. XXIX. 1843. Misc. 111: 



Spica brevi erecta, sepalis oblongo lanceolatis complicalis petalisque 



lanceolatis ascendentibus aequalibus, labello hemisphaerico apice ab- 



rupte in appendicem carnosam ovatam obtusam producto, marginibus 



basi tenuibus laceris aniplexicolumnibus , linea intramarginali carnosa 



inflexa connivente aperturam cordiformem elficiente, columna bicirrhosa. 



Caracas. Linden. Heceived by Rucker. 



. Alabastrum might be mistaken for C. trideniatum. Sepals and petals very pale 



dull green outside , are slightiy pink inside, richly spolted in irregular bars, with a 



deep crimson purple. Lip viewed from the side has a hemispherical forra, green, ex- 



cept at the base, where it is extended into a black-purple lacerated margin embra- 



cing the column, and at the point, where it isextonded into a long flat horn or nose. 



Seeu in front it is wholly of the same rich black purple and looks as if it were a 



solid hemisphere pierced in the middle with a large heart-shaped hole , but this ap- 



pearance is owing to a thick fieshy rim , which rises from within the true edges of 



ihe lip, and directing ilsell inwards horizontally with an uneven outline, at lasl louches 



in front of ihe column , and produces the appearance of a junction. Flowers have 



no smell.

Sepalis petalisque oblongis acutis secundis, labello carnoso subro- 

 tundo rostrato serrato et lacero basi fimbriato fovea alta triangulari in 

 medio. 



„Pseudobulbs 6—7". Light glaucous leaves, Flowers in a close raceme not at all 

 handsome. Differs from Catasetum saccatum in having much smaller flowers , with 

 sepals and petals turned upwards, the Jip more lacerated, than fringed, except quite 

 at the base. and the opening of the pouch triangular withoul ribs instead of being 

 crescentshaped with very conspicuous elevations on ihe side and next the base, — 

 Mi/anthns sanguineiis Linden. Greenish flowers, speckled with brown or dull red.
