PASSIFLORACE.X. 
PASSIFLORA QuELCHII, N. E. Brown, sp.n. (Plate 3.) Frutex vel arbor, glaber. Folia 
petiolata, cuneato-oblonga, acuta vel obtusissima, undulata, coriacea ; petiolus apice 
biglandulosus.  Stipulee minutze, subulatee, decidus. Cirrhi nulli. Flores in 
racemum abbreviatum dispositi, glabri. Calycis tubus elongatus, cylindricus. Sepala 
petalis subeonformia, oblongo-lanceolata, obtusa. Corona faucialis uniserialis, 
multipartita, segmentis 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—4 lin. distant, spreading, glabrous; petiole 4-6 lin. long, 
moderately stout, with two large sessile glands at the apex ; blade 3-5 in. long, 2-13 in. 
broad, cuneately oblong, gradually tapering from $ 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 noteh, 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 retieulated, 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 1-3 in. long, 
several-flowered, glabrous.  Pedicels 1-2 lin. long, glabrous. Calyx-tube about 1 in. 
long, 11-2 lin. diam. in the dried state, cylindric, slightly enlarged at the mouth, 
glabrous; the lobes 10-12 lin. long, 23-32 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 13 lin. long; the other at the mouth of the tube, 
consisting of numerous flattened, somewhat hatchet-shaped segments rather more than 
4 in. long, with the dilated part slightly toothed and dorsally produced into a short point. 
Gynophore nearly 13 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, MeConnell A: Quelch, 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.
