16 ART. I.—B. HAYATA: 
Has. Kachinro, leg. C. Owatari, Mart. 1898; Taitd, Iriyo- 
kukaku, leg. T. Kawakami et U. Morr, Dec. 1905 (No. 2149); 
Niki et Suichdriu, leg. C. Owatani, Jan. 1898. 
Distris. China and Indo-China. 
Osseryv. Covered by yellowish soft hairs; leaves trifoliolate, 
petioles 5 cm. long, leaflets ovate acute 8 cm. long, 34 cm. broad, 
obscurely dentate or nearly entire, lateral leaflets oblique at the 
‘base; panicles few-flowered, peduncles 4-5 cm. long; sepals 4, 
ovate, nearly acute, with yellowish soft hairs on the outside, 
glabrous inside ; stamens many, 12 mm. long, filaments hairy on 
the margin and outside, quite glabrous on the inside, anthers 
narrow, glabrous ; achenes hairy, fusiform with two distinct ridges, 
tails with long hairs. 
In my Flora Montana Formosz, I doubtingly referred this 
plant to C. Wightiana. After examining more carefully, I have 
found that the specimen is the same as the Philippine form of 
C. Leschenaultiana DC. The present plant differs from C. Wightiana 
in having fusiformed achenes and thread-like filaments. C. 
Leschenaultiana described in Kunrzz’s ‘* Monog. Clemat. p. 167,” 
has lanceolate leaves, while the Formosan plant has ovate 
ones. 
Clematis Leschenaultiana DC. var. angustifolia Hayara n. v.

acuminato basi acuto vel rotundato 7-8 em. longo, 24 cm. lato, remote 
serrato ad acumen integro, petiolulo 1 em. longo, foliolis lateralibus 
oblongo-ovatis acutis basi oblique rotundatis, petiolis foliorum 6 cm. 
longis. Flores szepe solitarii, vel paniculati, paniculis 2-3-floratis, 
pedunculis flavo-tomentosis. Achaenia fusiformia rostrata, caudis
