apicem vix (ad 0.8 mm) lobulatus, cum dentibus exterioribus 1.5-2.5 X 0.8-1 mm 

 lanceolatis instructus. Petala 12-14 X 5-9 mm, asymmetrice obovata apice obtusa 

 eciliata intus glabra extus modice granuloso-furfuracea. Stamina glabra 

 isomorphics ; filamenta 3.7-4.8 mm ; antherae subulatae curvatae 4-4.8 mm longae, 

 connectivo sub thecis paulo (ad 0.4 mm) producto postice in calcar acutum 0.8-1

Type : shrub 0.2-0.7 m, petals pink, anthers yellow, occasional in savanna 5 

 km west of eumbre camp, elev. 1900 m., Cerro de la Neblina, Terr. Amazonas, 

 Venezuela, Jan 6, 1954, Bassett Maguire, John J. Wurdack, & George 8. Bunting 

 37105 (NY). Paratypes (all from the west cumbre of Neblina): Maguire, 

 Wurdack, & Bunting 36927, 37085, 37295. 



The long- exterior calyx-teeth are reminiscent of the genus Meriania; however, 

 the character of the pubescence and the granulose ovaries indicate Graffenrii dn. 

 G. fruticosa seems to be the ultimate reduction of a line coming from G. 

 hitchcockii Gleason through G. rufa Wurdack. 



Graffenrieda reticulata Wurdack, sp. nov. 



G. fantasticae Schult. & Sm. affinis et in habitu similis, sed foliis trinerviis 

 nervulis bene reticulatis fructibus maioribus. 



Arbor parva, ramis crassis paulo quadrangularibus (cum cortice laevi sulcato 

 primum rufo-squamulosis mox glabratis. Petioli 1-1.5 cm; lamina glabra 6-10 

 X 3-6 cm, elliptica, apice rotundata vel paulo retusa, basi late acute vel anguste 

 obtusa. trinervia nervis lateralibus maxime 4-8 mm a marginibus distant ibvis. 

 nervulis supra obscuris subtus leviter elevatis secundariis numerosis tertiaris 

 bene reticulatis. Panicula glabra; Mores sessiles cum characteribus generis; 

 alabastra 4-mera, ovario 3-loculari apice rotundato glabro. Frnctus urceolatus 

 3-locularis ca. 8X4 mm ad torum ad 2.5-3 mm constrictus, calyce vix lobato. 



Type : tree 5-10 m, fruiting, common in scrub forest between cumbre camp 

 and west escarpment, elev. 1700-1750 m ; Cerro de la Neblina, Terr. Amazonas. 

 Venezuela, Jan 13, 1954, Bassett Maguire, John J. Wurdack, & George 8. 

 Bidding 37253 (NY). Paratype: bushy tree 3-8 m, buds greenish, occasional in 

 uppermost slope forest above Camp 4, elev. 1600-1700 m, Cerro de la Neblina, Jan 

 13, 1954, Maguire, Wurdack, & Bunting 37268. 



G. fantastica has 5- or indistinctly 7-nerved leaves with the tertiary veins not 

 obvious aifd an ovoid fruit less than 5 mm long. The paratype collection of G. 

 reticulata had buds sufficiently advanced to establish the genus and flower-mery 

 definitely. 



Graffenrieda sessilifolia Triana subsp. occidentalis Wurdack, subsp. nov. 



A subsp. sessilifolia differt petalis roseis ovario apice in collum ca. 1 mm 

 Longum protracto. 



Type: shrub or small tree 2-10 m, petals pale pink, anthers pale yellow, oc- 

 casional among boulders on hillside, elev. 1750 m, Cerro Yutaje, Terr. Amazonas, 

 Venezuela, Feb 17-19, 1953, Bassett Maguire & Celia K. Maguire 35289 (NY). 



Paratypes (all VENEZUELA, Terr. Amazonas): tree 5 m high, petals pink, anthers 

 yellow, frequent in scrub bush among boulders above Intermediate Camp, elev. 1200 m, Cerro 

 Yutaje, Feb 4, 1953, Maguire $• Maguire 35052; shrub 2 m high, flowers pink, occasional on 

 summit of Cerro Yutaje, elev. 2200 m, Feb 17-19, 1953, Maguire 4' Maguire 35331; small tree
