The following specimen probably also belongs here: Napo-Pastaza: Valley of the 

 Rio Pastaza and adjacent uplands, on cliff-top, near El Topo, 4,400 ft. elev., 

 Camp E-1687 (plants scrambling from mossy bank, or sometimes epiphytic; fruit 

 solitary, immature, sub^obose, about 8 mm. in diameter). It agrees with E. oliganthum 

 in length of pedicel, pubescence of calyx, and the comparatively inconspicuous 

 disk; however, its leaves are slightly different in shape and venation, and I hesitate 

 to make a positive identification of it without flowers. 



Eleutherostemon gracilipes A. C. Smith, sp. nov. 



Frutex praeter flores ubique glaber, ramulis gracilibus obtuse angulatis; stipulis 

 obscuris coriaceis pulvinatis haud 1 mm. longis; petiolis subteretibus rugulosis 

 1-2 mm. longis; laminis papyraceis in sicco fuscis lanceolatis vel ovato-lanceolatis, 

 7-11 cm. longis, 1.5-5 cm. latis, basi late obtusis vel rotundatis, in acuminem 

 gracilem obtusum ad 2 cm, longum gradatim angustatis, margine paullo recurvatis, 

 subtus minute et dispersim glanduloso-strigillosis, basim versus 5-xierviis, costa 

 et nervis secundariis (intimis cum costa ad 2 cm. concurrentibus) adscendentibus 

 supra leviter impressis subtus elevatis, rete venularum supra plerumque immerso 

 subtus prominulo; floribus axillaribus ut videtur solitariis, bracteis basalibus 

 paucis obscuris; pedicellis gracillimis sub anthesi 20-30 mm. longis minute albido- 

 puberulis basim versus minute bibracteolatis superne obscure glandulosis; calyce 

 sub anthesi 4. 5-- 5 mm. longo et apice diametro albido-puberulo, tubo cupuliformi 

 2.5-3 mm. longo basim versus obscure rubro-glanduloso, limbo erecto-patente sub- 

 membranaceo circiter 2 mm. longo minute 5-dentato (dentibus apiculatis circiter 

 0o5 mm. longis), sinibus complanatis; disco annulari-pulvinato carnoso glabro; 

 corolla tenuiter carnosa glabra anguste cylindrico-campanulata sub anthesi 20-22 

 mm. longa., basim versus circiter 4 -mm. superne 7-8 mm. diametro, lobis 5 reflexis 

 obtusis circiter 4x3 mm.; staminibus 10 longitudine corollam fere aequantibus, 

 filamentis liberis membranaceis ligulatis circiter 13 mm. longis utrinque villoso- 

 puberulis (pilis circiter 0.3 mm. longis), antheris 7-7.5 mm. longis, thecis levibus 

 circiter 2.5 mm. longis basi rotundatis, tubulis 5-5.5 mm. longis per rimas ovales 

 1-1.5 mm. longas dehiscentibus; stylo filiformi corollam subaequante, stigmate 

 minuto. 



Santiago-Zamora: Eastern slopes of the Cordillera, valley of the Rio Negro, 

 junction of RIos Pailas and Negro (on the trail to Mendez), 6,000-7,500 ft. elev., 

 Aug. 20-24, 1945, Camp E-4924 (coll. F. Prieto) (TYPE US 1,989,113; dupl. NY) 

 (shrub 3 m.; leaves deep green above, bright green and subnitid beneath). 



Eleutherostemon gracilipes is immediately distinguished from its congeners by 

 its comparatively long pedicels and corollas and its greatly elongated filaments. 

 In its solitary flowers and puberulent calyx it suggests the preceding new species 

 (E. oliganthum), but in floral dimensions the two are very distinct.
