aggregatis, pedicellis capillaceis, fructiferis folia superantibus.—Columbia. 
Affinis videtur P. orbicularit, Humb. et Kunth, sed diversus, Ramuli tenelli, uti folia exacte alterni, 
pinnatim dispositi, ultimi tenues. Stipule lanceolate, membranacee, scariose, petiolo breviores. Folia 3-3} 
lin, longa, 24-3 lin, lata, omnia apice obtusissime truncata vel retusa, costa media interdum in mucronulam 
brevem excurrente, basi obtusa vel breviter cuneata, membranacea; petiolo tenui 3-1 lin. longo, Flores 
utriusque sexus ex iisdem axillis orti, foeminei solitarii, masculi numerosi in cymam trichotomam dispositi, pedun- 
culo tamen communi ramisque ita brevibus ut pedicelli fasciculati videntur. _ Pedicelli singuli ex axilla bractez 
parvee orti, graciles, fere capillacei, 3-5 lin. longi. Calycis segmenta 5 vel 6, ovata, medio viridia, margine 
alba, inter se ineequalia. Columna staminea in maribus brevissima, antheris 3 subsessilibus. Ovarium in 
flore fcemineo sessile. Styli tres, brevissimi, obtuse bilobi, lobis brevissimis crassiuscule — stigmatosis 
radiantibus. Capsulam non vidi.

minibus 3.—San Blas to Tepic. 
Rami tenuiores quam in C. disticha, cortice cinereo. Ramuli steriles foliati, semipedales, folium pinnatum 
simulantes, leviter pubescentes. Folia 1-2-pollicaria, forma OC. distiche, sed in sicco non glaucescentia, supra 
lucidula, subtus ad venas pubescentia vel omnino glabra, minute pellucido-punctata. Racemi seu ramuli 
floriferi ultrapedales, graciles, pilis sparsis adpressis pubescentes, aphylli. Flores in glomerulis numerosi, 
magnitudine eorum C, distichw, in speciminibus suppetentibus omnes masculi. Calyx 6-partitus, segmentis 
3 exterioribus ovatis extus hirsutis, 3 interioribus paullo angustioribus glabris. Stamina 3, filamenta libera, 
calyce longiora, sub disco centrali trilobo inserta.

p. 145. t. 111.—A variable plant, spreading on the ground, or creeping on shrubs; the leaves as well 
as the lip of the flower sometimes scarcely mucronate, at others bearing a rather long point. The 
smell, resembling that of A. clematitis, is very strong, even in dry specimens.—Panama.
