DC. Prodromus. The Arbroath cliff plant I can only look upon as 

 starved type." — E. S. Marshall. " Yes, the correct name for the 

 species is T. duhium Sibth. Fl. Ox. 1794." — Gr. C. Druce. 



Securigera Securidaca (L.). Garden weed, Dalton, v.-c. 69b, 

 August 9, 1914. If attempts be made to grow this from the seeds 

 supplied, the testa should be pierced before sowing, otherwise most of 

 them will remain like a piece of flint, no matter how wet the soil may 

 be. It is a most interesting plant to watch. The earliest umbels, in 

 this quarter at anyrate, are microscopic in almost every particular. 

 Mr Druce kindly named the plant for me. The faded unpressed 

 pieces are included to show the length of the mature umbel stalks. — 

 D. LuMB. "Yes, the Bonaveria Securidaca (L.) Desv. The genus 

 Bonaveria Scopoli dates from 1777 ; that of Securigera DC. only from 

 1805."— G. C. Druce. " Yes."— A. Thellung. 



Lotus siliquosus L. {Tetragonolobus sUiquosus Roth). Chalk 

 Downs, near Streatley, Berks, May 1914. First found 1911, well 

 established. — Coll. V. C. Murray ; comm. G. C. Druce. 



Lotus uliginosus Schk., var. glahriusculus Bab. Wet lane, Petit 

 Bot, Guernsey, August 1, 1914. Very similar to a plant distributed 

 last year through the Watson Exchange Club by Mr Standen, and so 

 named by Mr Salmon. Is it var. glaber of Breb., and the same as var. 

 a. suh-glaber of Syme E.B. — "sub-glabrous with the leaflets ciliated at 

 the margins 1 " These specimens grew in the damp hedgerow of a 

 " water lane" and were very different in general appearance from the 

 hairy form growing near by on dryer ground — W. C. Barton. 

 " Doubtless right. But I think that the amount of hair varies accord- 

 ing as the locality is wet or dry." — E S. Marshall. "May pass, I 

 think, but not so extreme as specimens sent me by Mr R. S. Standen 

 from Lindfield, Sussex, in 1911. Rouy {Fl. Fr.) segregates L. uligi- 

 nosus into L. glahriusculus Bab. and f^. villosus Lamotte. Our 

 commoner plant is certainly the latter. Rouy remarks that the 

 flowers of glahriuscula do not become green (or only slightly so) when 

 dry, whereas those of villosus usually show this change. This is borne 

 out in my herbarium specimens and in Mr Barton's example before 

 me." — C. "E. Salmon. " Yes, but Bab. in ed. 2 of his Manual, put it 

 as a variety of L. major, hence if his name for it is used ' Bab.' 

 should be in brackets. Br^bisson in his Fl. Norm. 87 (1858), under 

 L. uliginosus hsidi a var. glaber (as in my List)." — G. C. Druce. 



Lotus tenuis Waldst and Kit. Rough pasture, clay washing on 

 chalk, under "Eagle's Nest," Offley Hill, Hitchin, Herts, v.-c. 20, 

 August 10, 1914. L. tenuis in N. Herts occurs (1) on heavy boulder 

 clay ; (2) on the chalk scarp, in poor soil with a washing of marl or of 

 clay from the caps on the hills. It generally occurs with L. cornicu
