bluntly keeled. The flower is represented as about 1^ inch in 

 diameter, with lax and nprrov.- petals, -'•t is certainly very dis- 

 tinct from P. niagninunctat«i , and bears no resemblance whatever to 

 P. compecta.

P. Purpusii, N. E. Bp. — Plant similar to P. magnipunctata , 

 but the leaves are often less stout, and are more acute, end the 

 solitary and sessile flov/ers are quite different. Calyx cylindric, 

 sub-equally 6-lobed; lobes 4^-6 lines long, lanceolate, acute, 

 vrith narrow membranous ed^es. ^orolla 2i--3 inches in diameter, 

 expending in the afternoon irrespective of sunshine and closing be- 

 tween 5 and 6 p.m., pleasantly scented; netals numerous, in 2-3 

 series, sometimes \«/idely spreading, at other forming a some^vhat 

 funnel-shaped corolla, somewhat lax, 18-21 lines long, 2/3-ii line 

 broad near the tips, thence gradually tapering dovmwards into a 

 long, claw-like part, mostly more or less acute, sometimes obtuse, 

 .v;hite for 8-9 lines of their length at the base, bright yellov/ at 

 the upper part, and whitish -yellow, sometimes tinged v/ith red, at 

 the tips on the back. Stamens about 6 lines long, the central col- 

 lected together, the outer gradually separating and loosely erect; 

 fialaments not bearded, v;hite; anthers yellow, ^lands very small, 

 yellowish. Stigmas 10, about 8 lines long, filiform, with short

Described and from living plants. ■^t_ is one of those mentioned 

 in the Gardeners' Chronicle, 1926, Vol. LvJQC^ p. 213 ^ under P. 

 magnipunctata, as being cultivated under that name. Its leaves, 

 hov;ever, are usually less stout and more acute, end the long, 

 slender, white bases of the petals give the flower a distinct ap- 

 pearance. 



P. magnipunctata, N, E. Br.-- '^o this should be added as a syn-
