New or Little Known Plants of Japan. 
= 
green and with a central longitudinal broad white space on the upper, glaucous on the under surface, 2—3 
inches long, 10o—15 lines broad; petioles short, marginate, canaliculate, 1—2 lines long. Peduncles from 
the axils of upper leaves, 1—2-flowered, slender, arcuate, if 2-flowered forked a little beyond the middle, 
I—1¥% inches long. Flowers nodding, stipitate, sweet-scented; stipes 4 line long. Perianth white, clavate- 
cylindrical, swollen above the middle, rounded at the base, smooth outside, puberulent inside, 6-lobed at 
the apex, 9 lines long, 2% lines broad; lobes in 2 rows, greenish, ovate, pubescent at the apex, at last 
recurved, about 2 lines long. Stamens 6, opposite the lobes of the perianth, included, those opposite the 
inner 3 lobes somewhat longer than the others; filaments filiform, hairy, adnate to the perianth for their 
lower half, about as long as the tube of the perianth, the upper free portion about 3 lines long; anthers 
connivent, linear-ovate, erect, 2-lobed at the base, dorsifixed, about a line long, the 2 cells dehiscing 
introrsely. Ovary sessile, ovoid, 3-celled, about 1 line long; style filiform, elongating beyond the 
anthers after anthesis, about 7 lines long; stigma terminal, small; ovules attached to axile placentae, 
uniseriate and about 3 in each cell.—F Il. May. 
The figure was drawn from a living specimen brought from the Botanic Garden of the Imperial 
University. The specimens of this plant in the Garden were collected a number of years ago either in 
Shinsht or Nikko. 
From the brief description of its author P. lasianthum, Maxim. (Mel. Biol., vol xi., p. 850.) seems to 
be nearly related to the present species. But the characters of the inflorescence and leaves seem to 
divide the two species.
