I. 721 (1006). — M. sect. Gymnomeles Koehne, Deiitsrh. Doiulr. 2.^57 (1893), 

 pro parte. — Leaves conJiiplieate in bud, usually more or less lobed: calyx 

 deciduous or sometimes persistent: styles 3-5: loeules of ovary not extend- 

 ing with their ai)ex to the base of style and core of fruit not protracted 

 into a free pointed apex; fruit without or with few grit-cells. 



Subsect. 3. SiEBOLDTANAK, subscct. nov. — Calyx caducous, leaving 

 a large shallow scar: styles 3-5, villous at base: leaves of flowering branch- 

 lets not lobed; those of shoots partly 3-5-lobed, rarely not lobed: fruit 

 subglol)o^o, without grit-cells, small. 



9. 3/. florihuyida Sieb. — 10. M. zumi Rchd. — 11. M. Sieboldii 

 Rehd. ^ — 12. M. Sargcntii Rehd. — The species of this group are all 

 closely related. — Japan and Korea. 



Subsect. 4. Kansuexsks, subsect. nov. — Calyx usually tardily decidu- 

 ous, leaving a small d*vply impressed scar, sometimes partly or wholly 

 I)ersistent: styles 3-5, glabrous: all leaves more or less lobed except in J/. 

 fiisca: fruit ellipsoidal, without or with few grit -cells. 



13. M, fusca Schneid. — 14. M, transitoria Schueid. — 15. M. kansiicn- 

 sis Schneid.^ — 16, M, Komarovii Rehd. — 17. M. honanensis Rehd.— 

 The first two sj^ecies of this group form a transition to the preceding sub- 

 section on account of the absence of grit-cells in the fruit and of dots on the 

 fruit and the first also in its only partly thrrr -lobed leaves. The following 

 two species have their fruits dotted and with a few grit-cells; of the last 

 species which forms by the shape of its leaves a transition to I he subsect. 

 Yunnanenses the fruit is not yet known. — Western North America, east- 

 ern Asia. 



Subsect. 5. Florextinae, subsect. nov. — Calyx deciduous: leaving a 

 small deeply impressed scar: styles 5, villous at base: all leaves lobed with 

 several l(>l>es on each side: fruit broadly ellipsoidal, without grit-cells. 



18. M. Jlorentina Schneid, — Italy. 



Subsect. 6. YuNXANENSES, subsect. nov. — Calyx persistent: styles 5, 

 glabrous or nearly so: leaves slightly lobed with several lobes on each side 

 or not lubcd: fruit subglobose, about 1 cm. across, dotted, with grit-cells. 



19. M, PraUii Schneid. — 20. M. yvnnarien.sis Schneid. — The first 

 species seems to have some relation to the subsect. Kansuenses, while il/. 

 yunnanensis has leaves siniilar to those of J/. Tschono.skii. — Western 



China.

 Trees & Shrubs, ii. 142 (IDll). — Leaves condupHcate in bud, at least the 

 leaves of shoots lobed, rarely without lobes: calyx persistent: styles 5, villous 

 at base; anthers red or reddish; loeules of ovary extending with their apex 

 above base of style and core of fruit with free pointed apex: fr. subglobose 

 or depressed, 2-5 cm. across, green or yellowish green, not dotted, without 

 grit-cells. 



^ Tho styles of this species are glabrous in our specimens, not pilose as described by Batalin.
