PASSIFLORACEjE. 



Passiflora Quelchii, N. E. Brown, sp. n. (Plate 3.) Frutex vel arbor, glaber. Folia 

 petiolata, cuneato-oblonga, acuta vel obtusissima, midiilata, coriacea ; petiolus apice 

 biglandulosus. Stipulse minutoe, subulatae, decidual. Cirrhi nulla. Flores in 

 racemum abbret datum dispositi, glabri. Calycis tubus elongatus, cylindricus. Sepala 

 petalis subconformia, oblongo-lauceolata, obtusa. Corona faucialis nni serial is, 

 multipartita, scgrnentis complanatis prope apicem dilatatis oblique acuminatis; 

 corona interior e tubo versus basin emergens, multipartita, segmentis complanatis 

 lineari-falcatis. 

 Shrubby or arborescent, not climbing; branches woody, glabrous. Leaves simple, 

 entire, very coriaceous, 2-1 lin. distant, spreading, glabrous ; petiole 4-6 lin. long, 

 moderately stout, with two large sessile glands at the apex ; blade :}-5 in. long, §- 1 \ in. 

 broad, cuneately oblong, gradually tapering from f the way up in a slightly curved line 

 to an acute base, shortly acute or very obtuse and slightly emarginate with an apiculus 

 in the notch, with strongly undulated margins ; primary lateral veins 12-15 on each side 

 of the midrib, very spreading, uniting close to the margin in a series of broad loops ; 

 secondary veins much reticulated, all prominent on both sides. Stipules minute, 

 subulate, very deciduous. Tendrils none. Flowers in short racemes or clusters, 

 probably on the older parts of the branches; axis of the inflorescence §-§ in. long, 

 several-tiowered, glabrous. Pedicels 1-2 lin. long, glabrous. Calyx-tube about 1 in. 

 long, H-2 lin. diain. in the dried state, cylindric, slightly enlarged at the mouth, 

 glabrous; the lobes 10-12 lin. long, 2^-JU lin. broad, oblong-lanceolate, obtuse or 

 subacute. Petals similar to the calyx-lobes and of about the same size. Corona in two 

 series ; one placed towards the bottom of the calyx-tube, consisting of numerous linear- 

 falcate, acute, erect filaments about 14 lin. long; the other at the mouth of the tube, 

 consisting of numerous flattened, somewhat hatchet-shaped segments rather more than 

 \ in. long, with the dilated part slightly toothed and dorsally produced into a short point. 

 Gynophore nearly 14 in. long, terete or perhaps sulcate at the base, glabrous. Filaments 

 of the stamens 2 lin. long. Ovary oblong, 9-striate; styles 2 lin. long, stigmas capitate. 

 Ireng Valley, McConnell 8f Qnelch, 207. 



A very distinct species, easily distinguished from all the others of shrubby habit by its 

 cuneately oblong, undulated leaves, shortly racemose flowers, and long calyx-tube, besides 

 other characters.

dense tomentosis. Umbelhe composite, longe pedunculatse, fulvo-tomentosae,
