 flowers toward the end of June. 



A late-flowering species which under cultivation 

 has yet to show its qualities in perfection is S. 

 tomentella. I saw this plant in flower for the first 

 time on July 9, 1908, on the frontiers of eastern 

 Thibet at an altitude of nine thousand feet, and I 

 thought then that I had never before seen such a 

 handsome species of Lilac. It had foot-high, broad 

 panicles of pink to rosy lilac colored flowers and on 

 other bushes they were white. The plants were 

 from eight to fifteen feet high, much-branched yet 

 compact in habit, and the wealth of flower clusters 

 made it conspicuous from afar. The leaves are 

 elliptic-lance-shaped or rather broader, from four to six 

 inches long and more or less hairy on the underside. 

 In 1903, I had collected in the same locality seeds 

 of this Lilac and successfully introduced it to culti- 

 vation. Being rather variable in certain characters 

 it has received several names (S. Wilsonii, S. Rehderi- 

 ana, S. alborosea), but it must be known by its 

 oldest name of S. tomentella. Under cultivation it 

 has flowered several times and I am patiently wait- 

 ing for it to show its real character. 



Of the late-flowering Lilacs the best known in this 

 country and perhaps the hardiest of all is S. villosa,
