560 WILSON EXPEDITION TO CHINA 



Some of our specimens agree with Franchet's variety a. crinita, others with his 

 j8. myrtifolia; others are intermediate between these varieties. The leaves vary- 

 considerably in shape even on the same shoots as does the development of 

 setae and pubescence. With the evidence before us we do not think the above 

 varieties of Franchet should be retained. Vaccinmm setosum Wright is identical 

 and was probably described without knowledge of Franchet's name.

Western Szech'uan: Mupin, on rocks, alt. 1000-1300 m., Octo- 

 ber 1910 (No. 4294; bush 1-3 m. tall, fruit black); Mt. Omei, June 

 1904 (Veitch Exped. No. 5138; bush 6 m. tall). Yunnan : Mengtze, 

 alt. 2000 m., A. Henry (Nos. 9170, 9170^, 9170'); Yuan-chiang, alt. 

 1600 m., A. Henry (No. 13404). 



This is a very rare plant in Szech'uan, differing in no marked manner from the 

 typical Indian form. 



A new variety of this species is the following: 



Vaccinium Dunalianum, var. urophyllum, Rehder & Wilson, n. var. 



A typo recedit ramulis hornotinis breviter denseque villosulis, foliis ellipticis, 

 subito caudato-acuminatis, costa venisque utrinque elevatis conspicuis, costa sub- 

 tus et petiolis villosulis. 



Yunnan: Mengtze, mountains to the south-east, in forests, A. Henry (No. 

 giTO"). 



This variety is easily distinguished by the puberulous shoots and petioles and the 

 long-caudate leaves. 



Vaccinium urceolatum Hemsley in Jour. Linn. Soc. XXVI. 16 (1889). 



Western Szech'uan: Hung-ya Hsien, on red-sandstone rocks, 

 alt. 800 m., June and October, 1908 (No. 1072, in part; bush 60 cm.- 

 2 m. tall, flowers pink, fruits black) ; Wa-shan, on rocks, alt. 2000-2600 

 m., October 1908 (No. 1072, in part; bush 1-2 m. tall, fruit black). 

 Mt. Omei, June and November 1904 (Veitch Exped. Nos. 3924, 5136); 



This plant is common in the above localities and is partial to sandstone boulders.

Western Szech'uan: Mupin, on cliffs and tree-trunks, alt. 

 2300-2800 m., June and November 1908 (No. 1259; bush 60-120 cm. 

 tall, flowers rose-pink, fruit black) ; same locality, alt. 2300-2600 m.,
