Aristolochia longa Thunberg, Fl. Jap. 144 (non Linnaeus) (1784).

De Candolle, Prodr. XV. pt. 1, 497 (1864). — Hemsley in Jour. Linn. 



Soc. XXVI. 363 (1891). 

 Aristolochia recurvilabra Hance in Jour. Bot. XI. 75, fig. (1873); XVIII. 



301 (1880). — Franchet in Nouv. Arch. Mus. Paris, s^r. 2, VII. 67 (re- 



curvilabris) {PI. David. I. 258) (1884). 



Kiangsi: Kiukiang, roadside thickets, alt. 100 m., July 29, 1907 

 (No. 1507; climber 3 m., flowers dark). Western Hupeh: Ichang, 

 grassy hills, alt. 30-300 m., September 1907 (No. 1986; flowers dark). 



Very common at low altitudes round Kiukiang, rare at Ichang. 



Aristolochia thibetica Franchet in Jour, de Bot. XII. 313 (1898). 



Western Szech'uan: Tachien-lu, thickets, alt. 2300 m., August 

 1908 (No. 1985; climber 2 m., flowers with chrome-yellow lip and 

 bronze-colored throat). 



On our specimen most of the leaves are obovate-oblong to panduriform; other- 

 wise it agrees well with Franchet's description. The fruit is smaller and has more 

 prominent and wider wings than that of A. heterophyUa Hemsley, and the short 

 petioles and different-shaped corolla also serve to distinguish it from Hemsley 's 

 species. The plant is rather rare.
