REPORT FOR 1913. 



497 



Salix alba x triandra (Salix undulata Elirh.) Port Meadow, 

 Thames side, but planted, Sept. 1913. — G. C. Druce. "Correct." — 

 E. F. Linton. 



Salix viminalis L. [Ref. No. 76.] Pond, Messing, v.-c. 19, 

 Essex N. Flowers March 30. Leaves Aug. 17, 1913. A tree 20 ft., 

 branches sub-erect, leaves dark green. — G. C. Brown. " There is 

 nothing abnormal in the leaves of this specimen of S. viminalis L., 

 the breadth of which is liable to some variation. Some of the stigmas 

 appear to be rather short, but they are mostly of the usual length on 

 the more advanced catkins." — E. F. Linton. 



Salix phylicifolia L. [Ref. No. 1.] Bank of River Dochart, 

 Killin, Perth, June 17, 1913. [Ref. No. 2.] same data. With 

 glabrous ovaries. [Ref. No. 4.], with densely hairy ovaries. Coll. 

 A. Wilson and J. A. Wheldon. Nos. 1 and 2 were named by the 

 Rev. E. F. Linton. 



Salix Andersoniana x phylicifolia. [Ref. No. 3.] Banks of the 

 Dochart, Killin, Perth, v.-c. 88, June 17, 1913. So named by the 

 Rev. E. F. Linton, who thinks it may, however, possibly be a form of 

 S. phylicifolia.'— J , A. Wheldon. 



Populus canescens Sm. Planted.) The Grange, Stevenage, 



Herts, V. c. 20, 1913. I have, as yet, only found the ^ tree in N. 

 Herts and E. Beds. This makes it probable that the tree is not here 

 indigenous.— J. E. Little. " Yes, very characteristic." — Ed. 



Populus tremida L., sucker-shoots. [Ref. No. 3802.] In a 

 birch wood. North of Loch Tummel, Mid Perth, v.-c. 88, July 1.9, 

 1913. This is probably the tj^pe, as Dr Moss tells me that in var. 

 villosa (Lange) the leaves of the sucker-shoots are decidedly cordate- 

 based, which is not the case here; in the Highlands also, the type 

 {a. glabra) seems to be by far the more common form. — E. S. 

 Marshall. 



Ceratophyllum submersum L., c. fr. Braunstone Pool, Leic. 

 Discovered by the Rev. H. P. Reader. New record for v.-c. 55. 

 Coll. W. E. Mayes, July 1913 ; comm. A. R. Horwood. "Yes, the 

 single fruit on my specimen seems quite spineless." — C. E. Salmon. 

 " From foliage only. I should have thought this C. demersum L." — 

 E. S. Marshall. " From its slenderness, one would so name it, but 

 the leaves are decidedly serrulate which C. demersum always is, while 

 C. submersum is said to have the leaves ' not serrulate.' " — A. Bennett. 



Helleborine jmlustris Schk. Abundant at Sandscale, Dal ton, Sept. 

 15, 1913.— D. LuMB.
