SALIC ACE AE. — SALIX 97 



sperma Roxburgh as understood by me, as that species may be planted through- 

 out the tropical regions of that part of the world. Unfortunately 1 have not seen 

 any of the above-mentioned specimens. The d' plant is still unknown.

Salix tetrasperma Beddome, Fl. Sylv. S. Ind. II. 302, t. 302 (cxclud. fig. 11-

INDIA. Pondicherry: near Karikal, 1836, G. S. Perrotet (type, ex An- 

 dersson); Mysore: Shevary Hills (ex Wight); Madras Presidency : Madras, 

 near Salem (ex Wight; probably the same as Wallich, Cat. No. 3702, ex Herb. 

 Wight, of which I have seen a photograph); Assam : Khasi, " reg. trop. 2-4000 

 ped.," J. D. Hooker & T. Thomson (cf and 9 specimens ex Herb. Ind. Or., distributed 

 as S. tetrasperma). 



The plant from Khasia which I take for this species agrees very well with Wight's 

 description and plate. The ovaries are hairy and the pedicels shorter than the 

 bracts. There are only 3 or 4 stamens in the cf flowers, while Wight's plate shows 

 5 stamens and Andersson says: " stamina octo." 



There may occur in India different species of Salix of this section with pubescent 

 ovaries, and a critical study could only be made with a large amount of material. 

 The tree Willows in the tropical and subtropical parts of India and eastern Asia 

 seem to be widely spread by planting, and it is therefore diflBcult to fix the Umits 

 of their geographical distribution. 



7. Salix tonkinensis Seemen, in Bot. Jahrb. XXI. Beibl. LIII. 53 (1896). 

 INDO-CHINA. Tongking: near Tu Fap, in swamps, December 1887. A. 



Balansa (No. 3787; tree 2-5 m. tall, ex von Seemen); Notre Dame (Black River), 

 behind the rock, A. Balansa (No. 3788, ex von Seemen). 



In the grayish brown pubescence of the twigs and leaves this species seems 

 to resemble S. Kusanoi Schneider, but the capsules are loosely hairy and there 

 is only one gland as in S. tetrasperma Roxburgh. For other characters see the keys 

 on p. 74 and p. 86.
