1. D. staminea, Brown; Wall. PI. As. rar. t. 191; Bot. Beg. xxxiii. 

 t. 13. Vern. Mtmeti, Kamaon. 



A shrub, branchlets and inflorescence scabrous with grey stellate 

 pubescence. Leaves lanceolate or ovate-lanceolate, 1-2 J in. long, on short 

 petioles, rough on both sides with stellate pubescence, grey beneath. 

 Flowers white, fragrant, on short trichotomous panicles, with linear 

 bracts, at the ends of branchlets. Calyx-teeth triangular acute, somewhat 

 shorter (when in flower) than the cup-shaped tube. Petals oblong, pubes- 

 cent outside. 



Himalaya, 5000-8000 ft., from Kashmir to Bhutan. Fl. May, June. Hardy 

 in England. A variety with larger flowers is D. Brunoniana, Wall. 



2. D. corymbosa, Brown ; Koyle 111. t. 46, f. 2 ; Bot. Eeg. xxvi. t. 5. 



A shrub, not scabrous ; branchlets and leaves with scattered, soft, stel- 

 late hairs or scales ; bark peeling off in long shining rolls. Leaves ovate- 

 lanceolate, long-acuminate, 2-5 in. long, on short petioles. Flowers white, 

 in broad, trichotomous, corymbose panicles, at the ends of branchlets ; 

 bracts small, deciduous. Calyx-teeth ovate, obtuse, shorter when in flower 

 than the hemispherical tube. Petals broad-obovate or rounded, glabrous. 



Himalaya, 6000-10,000 ft., from Sutlej to Bhutan. Fl. May, June. Hardy 

 in England. 



3. PHILADELPHUS, Linn. 



Shrubs, often with stellate hairs. Leaves and branches opposite ; no 

 stipules. Flowers white or straw-coloured, axillary or corymbose. Calyx- 

 tube turbinate, adnate to the ovary, with 4, rarely 5 lobes, valvate in bud. 

 Petals 4, rarely 5, convolute in bud. Stamens 20-40, inserted under the 

 edge of the epigynous disc ; filaments subulate ; anthers globose. Ovary 

 3-5-celled ; styles 3-5 ; ovules numerous, imbricate. Capsule turbinate, 3- 

 5- celled, dehiscing loculicidally. Seeds numerous, testa membranous, 

 reticulate ; albumen fleshy. 



1. P. coronarius, Linn. Syn. P. tomentosus, Wall.; Eoyle 111. t. 46 f. 1. 



A shrub, branchlets glabrous. Leaves ovate, sometimes elliptic, acumi- 

 nate, dentate with distant teeth, clothed beneath with long soft white 

 hairs, 2-3 in. long, on petioles J-^ in. long ; three pairs of main lateral 

 nerves, two from the base or from near the base, arcuate, the innermost 

 pair nearly meeting at the apex of the leaf, a third pair generally half- 

 way up the midrib. Flowers axillary, in short racemes at the ends of the 

 branches, strongly scented. Calyx-lobes pubescent inside, ovate, nearly 

 as long as calyx-tube. Style deeply 4- or 5-cleft, as long as stamens or 

 shorter. 



North-West Himalaya, Kishtwar to Kamaon 6000-10,000 ft., Sikkim. Fl. 

 May-July. Also in Japan, China, Mantshuria, the Caucasus, and (indigenous 

 or naturalised) in Central Europe. Hardy in England. I cannot find any 

 specific difference between the European and Himalayan shrub. The former is 

 less hairy, and has more elliptic leaves.
