184 WILSON EXPEDITION TO CHINA 



Rhus Delavayi, var. quinquejuga, Rehder & Wilson, n. var. 



A typo recedit foliis 2-5-jugis, rarius pluri-jugis cum petiolo 12-18 

 cm. longis, foliolis basi manifests obliquis 2-7 cm. longis initio utrin- 

 que sparse adpresse pilosulis mox glabris. 



Western Szech'uan: south-east of Tachien-lu, woodlands, alt. 

 1600 m., October 1908 (No. 1260, type; small tree 6 m. tall); valley 

 of Tung river, May 1904 (Veitch Exped. No. 3372). 



This variety is rather local and is well distinguished from the type in the char- 

 acters mentioned above. The relationship between this plant and R. succedanea 

 Linnaeus is evidently very close but the latter has rather different flowers, larger 

 panicles and larger, more coriaceous leaves. The rather large petals with promi- 

 nent dark pinnate veins and the nearly white sepals are characteristic of R. De- 

 lavayi Franchet, and its variety. 



Here may be added a note on a species not collected during the Arnold Arbore- 

 tum Expeditions. 



Rhus paniculata Wallich, Cat. No. 993 (nomen nudum) (1828). — Hooker f., 

 Fl. Brit. Ind. II. 10 (1876). — Engler in De Candolle Monog. Phaner. V. 421

 Yuan-chiang, alt. 1300 m., A. Henry (No. 11578^; bush 2 m.). 



In China this plant has been previously recorded only from the extreme south- 

 western corner of Yunnan.
