Type: alt. 4000 m, Puerto Cabello, Carabobo, Venezuela, June 1846, Funek 

 & Schlim 714. Holotype Herb. Boissier, Geneva; isotype Herb. Delessert, Geneva. 



Apparently C. cochlanthera has not been again collected. 



2. Clusia orthoneura Standi. Field Mus. Pnbl. Bot. 22: 91. 1940. 



Medium-size tree, 12-18 m high, the branchlets slender, scurfy-rimose, sili- 

 cate when dry; leaf-blades oblanceolate, coriaceous, acuminate or merely obtuse 

 at the apex, acute at the base, 6-12 cm long, 2.5-3.5 cm broad, the midrib extend- 

 ing to the middle of the blade, the lateral veins prominulous, ascending at angles 

 of 75-80° and parallel above; petiole 8-14 mm long; inflorescence open, (1) 5-7- 

 flowered; sepals apparently 6; petals apparently 6, ca. 3 cm long, obovate, "pink- 

 ish white"; staminal column ca. 6 mm high, 7 mm thick, glutinous, thick-walled, 

 the central cavity narrow, the central staminodial mass lacking; stamens ex- 

 trorse, ca. 20, the filaments 6-7 mm long, the anthers 2.5 mm long, strongly in- 

 curved; pistillate flowers unknown. 



Type : epiphytic tree 40-60 ft high, 2-3 inches diam., petals pinkish-white ; 

 stamens yellow, a very sticky substance collected at base; at 3600 ft alt., Mt. 

 Chapon. nw Bogota, extreme western part of Dept. Boyaca, Colombia, June 2, 

 1932. A. E. Lawrance 131. 



Specimens examined: Lawrance 131 (isotypes K, NY); tree, petals pinkish-white, forest 

 above Pandi at 1800-2000 m alt., Dee 1-3, 1917, F. W. Pennell 2824 (NY). 



Clearly, in the sect. Cochlanthera, C. orthoneura stands next to C. cochlan- 

 thera, as indicated by the comparatively few stamens. The leaf character of C. 

 orthoneura is unique in the section. 



3. Clusia centricupula Cuatr. Rev. Acad. Colomb. 8: 56. 1950. 



Type : arbol epifito ; flor rosada, bosque 5-20 m alt., Puerto Merizalde, Rio 

 Naya, Co&ta del Pacifica, Dep. Valle, Colombia, Nov 22, 1943, Cuatrecasas 14043 

 (holotype F, isotype NY). Paratype : arbolito epifito. Hoja craso coriacea, verde 

 amarillento clara. Flor rosada, Veneral bosque 5-50 m alt., Valle, Jan 30, 1944, 

 Cuatrecasas 15776 (F). 



Apparently known only by the two type collections. 



4. Clusia lunanthera Maguire, Bull. Torrey Club 75: 431. 1948. 



Type: tree 12 m high, 15 cm diam., latex orange, copious, petals totally 

 white, the flowers 8-10 cm diam., frequent, high bush about rim of Arrowhead

 head Basin, Maguire 24428 9 ; East Ridge, Maguire 24586 9 ; Savanna VIII, Maguire 24546 9. 



KnoAvn only from the Tafelberg, where it is a conspicuous member of the 

 summit flora.
