numbered "61. Trifolium — nouveau?" Then at Cambridge, in 

 Herb. Babington, I turned to the type specimens of T. pratense 

 y:\v.parviflorum Bab., which Mr. Burkill had found "identical with 

 T. pratense var. micropetahcm Lange." I believe the Paris plant 

 and my own, which was divided among Herb. Boissier, Herb. 

 Brit. Mus., and Herb. Cantab., are the same. In November, 1900, 

 Burkill read a short, interesting paper on " Trifolium pratense 

 var. parviflorum" before the Cambridge Philosophical Soc. (Proc. 

 Camb. Phil. Soc. xi. 29).* 



Finally, the wet weather probably accounted for the following 

 abnormalities : — Bubus saxatilis, runners ten feet long, and root- 

 ing at the nodes, below Binn, at 4700 ft. ; Malacliium aquaticum, 

 with shoots four feet long, on a damp shady bank in Langthal, 

 Binn ; and Fragaria vesca, with four-feet runners, falling over a 

 damp limestone cliff above Bex. In Binnenthal, at the end of 

 August, not a single ripe pod of the very rare Matthiola valesiaca 

 was to be seen, though there were two lingering spikes of the 

 pretty lilac flowers, and plenty of seedlings from last year. 



POPPY HYBEIDS. 

 By E. Adrian Woodruffe-Peacock, F.L.S. 



Our common poppies may be roughly arranged from the 

 general average of their stigmatic disc rays in the following 

 order : — Argemone 4, dubium 6, Lecoqii 8, strigosum 8, Bhceas 10, 

 Pryorii 11. Though my notes at present suggest that it is never 

 quite safe to argue from one soil or locality to another, yet at any 

 given place general averages from stigmatic rays can be fully 

 depended on. 



At a spot which had been freshly prepared for an invasion by 

 throwing sand out of the stream bed early in 1911, 1 found Bhceas 

 and dubium, in the proportion of 8 and 5, growing intermixed on 

 the bank of Cadney Beck. Though poppy seed of all kinds is 

 regularly water-carried, it was not till September that I could 

 detect the presence of strigosum, and then only in the smallest 

 quantity, approximately 1 to 5000. This season (1912) by the 

 first week in July it was there, too, in fair quantity ; roughly in 

 proportion witli the others of 8, 5 and 1. 



The number of rays in Bhoeas varied from 9 to 14, a range 

 of 6, in 200 flowers taken at random, and averaged a trifling 

 fraction under 10. In dubium the rays varied from 4 to 7, a 

 range of 4, in a hundred flowers, selected in the same manner, 

 and averaged exactly 6. In strigosum the rays varied from 7 to 

 10, a range of 4, in fifty flowers, practically all that were to be 

 obtained that day, and again averaged almost exactly 8. 



It is remarkable that though strigosum stands half- way between
