TEMPERATE HIMALAYA from BHOTAN to NIPAL, alt. 5000-8000 ft., abundant. 

 KHASIA MTS., alt. 4000-6000 ft. DISTEIB. Java, China, Philippines. 



Stems 5-9 ft. high, somewhat virgate. Leaves 3-8 in., tapering into the petiole, 

 pubescent or puberulous on the nerves, otherwise glabrous, usually narrow, some- 

 times obovate-lanceolate. Petals ~ in. long. Berry finally an intense blue. The 

 Chinese varieties have larger flowers than the Indian. 



10. DEUTZZA, Thunb. 



Shrubs with opposite branches and stellate pubescence. Leaves opposite 

 serrate, ovate or lanceolate, deciduous. Flowers white, corymbose in the In- 

 dian species. Calyx-tubs adnate to the ovary; teeth 5, small. Petals 5. 

 Stamens 10, subepigynous, filaments broadly winged the wing often ending 

 upwards in a tooth on each side. Ovary inferior, 3-5-celled ; styles 3-5, long ; 

 ovules numerous, axile. Capsule 3-5-celled, hemispheric or ovoid from a 

 rounded base, truncate at the summit, at length septicidal. Seeds minute, 

 numerous, obovoid-ellipsoid ; testa reticulate, a little longer than the nucleus, 

 appearing at last as a short stalk at its base, as a point at its summit. DISTRIB. 

 Species 7, Himalaya to North China and Japan ; and one outlier in Mexico.

TEMPERATE HIMALAYA, from KASHMIR to BHOTAN, alt. 6000-10,000 ft., frequent. 

 DISTRIB. China, Mantchuria, Amurland. 



Leaves 1-2 in., oblong or elliptic lanceolate ; on the under surface the stellate 

 hairs are often few, sometimes thickly scattered, not matted into tomentum in the 

 mature leaves ; under surface sometimes prominently reticulate. Petals glabrous or 

 stellately pubescent. Maximowicz 1. c. keeps the Chinese D. parviflora still distinct 

 by the puberulous smaller petals, the shorter teeth to the wing of the filament, the 

 leaves more prominently reticulate beneath, &c., none of which distinctions appear 

 to hold in the large Kew collection. The name corymbosa can only be preferred to 

 parviflora if Brown's naming in "Wallich's distribution be reckoned publication.
