280 WILSON EXPEDITION TO CHINA 
2 mm. longa, oblonga, obtusa, integra v. obsolete parce denticulata, glabra; petala 
breviter unguiculata, subspathulato-obovata, 5 mm. longa, 3 mm. lata, alba; 
stamina 22-24, majora ad 4 mm. longa; pistillum 2-4 mm. longum, subobsoletum 
(bene evolutum non vidi) Drupa ignota. 
Cultivated in the Späth Arboretum near Berlin, as "Prunus triflora” from 
Mandshuria. 
This species differs from Prunus triflora Roxburgh in the conduplicate leaves, 
scarcely, partly, or only slightly involute on the margin, the entirely glandless 
+ gerratures of the leaves, the very short pedicels, and in the smaller flowers. The 
fact that in the Plums conduplieate as well as convolute leaves occur is more and 
more confirmed.

Prunus triflora, var. pubipes Koehne, n. var. 
Pedicelli dense pubescentes v. rarius subglabri. Cupula ad tertiam v. dimidiam 
partem usque pubescens; stamina 19-22, quorum majora ad 3 v. 3.5 mm. longa. 
Cultivated in the Botanic Garden at Dahlem and in Spith’s Arboretum near 
Berlin. 
This variety differs except in its pubescence very little from the typical Prunus 
triflora, so that I can hardly believe in an hybrid origin of the var. pubipes. Transi- 
tional forms seem to be: P. Masu Hort ex Zabel in Beissner, Schelle & Zabel, 
Handb. Laubholz-Ben. 252 (nomen nudum) (1903), and P. Botan Hort., the pedicels 
and calyx of which are glabrous, or here and there sparingly pubescent.

1 Masu is an incorrect spelling; it ought to be Maru (= round in Japanese).
