Hants anp Berks Recorps.—I am glad to be able to note the 
occurrence of so scarce a plant as Limosella in North Hants, this 
making the fifth known locality for the county. On August 10th I 
found it growing in profusion on the margins of the plies stream 
near Wash Common, and as the stream forms the boundary of 
Hants and Berks, both counties may claim the plant. In Berk- 
— Limoseila is equally rare, only one other locality, near Sand- 
hurst, being recorded by Mr. Druce. At the spot where I found 
Laendis the Emborne is exceptionally low this year, the adjoining 
mill being not now worked, and this fact together with the dry 
summer has no doubt eactie Ay conditions favourable for the plant’s 
development. There was no trace of Limoselia when I used to 
ere it was probably of casual origin. This is the 
first certain record of nd —_ for Berkshire (see Fi. Berks, 
p. 487).—A. Bruce Jacks 
Diantuvs Uke seaanéice L.—I first found this about 1899, 
n 
since I have seen it in the same place. There i s only one small 
patch, about two hundred yards from an old pa and none in 
any other parts of the field or the surrounding ones. D. deltoides 
grows plentifully in a ype field only separated from it by a 
narrow lane.—Linuian M. Austin.

Tuts, the most recent addition to the series of translations of 
German ‘botanical works issued by the Clarendon Press under Pro- 
fessor Bayley Balfour's supervision, renders accessible to English 
readers a book of the first importance. Paul Knuth’s work on 
Flower Pollination replaces Hermann Miiller’s Fertilisation of 
Flowers by Insects and their Reciprocal Adaptations, the English 
edition of which appeared in 1883, as the standard work of refer- 
ae on pollination. Knuth’s work is based on Miiller’s, and the 
iking difference in size between the two is an index of the great 
davelostinent of the subject in the years which have elapsed since 
the appearance of the earlier work in 1878. Paul Knuth’ s Handbuch 
der Bliitenbiologie (1898-99) is well know b The 
author’s original idea was to republish, with 1 notes, Miiller’s classical 
work, on similar lines to those employed with Sprengel’s Entdeckte 
Geheimniss der Natur; which was issued in Ostwald’s “ Klassiker 
der Exakten Wissenschaften” in 1894 (see Journ. Bot. 1894, 218).
