Ixxxii PKOCEEDINGS OF THE EOYAL HORTICULTURAL SOCIETY. 



petals partially converted into stamens, the remaining flowers being- 

 normal. This inflorescence was taken from the plant which bore flowers 

 all having a similar malformation shown by Mr. Sutton before the 

 Committee on August 1, 1905. See Journ. R.H.S. xxxi. p. Ixxxi. 



Pisum sativum. — Mr. Sutton also showed a specimen of Pisum 

 sativum grown from seed collected by him from a plant growing semi- 

 wild in a vineyard near Jafta. The plant was about a foot high, had 

 much serrated leaves and stipules, coloured flowers, and short curved 

 pods. It had been crossed with the ' Duke of Albany ' pea, and had 

 produced a tall plant (which w^as also shown) somewhat intermediate in 

 the 'foliage, having a dark-coloured spot in the axil of the leaves, coloured 

 flowers, and intermediate somewhat curved pods. 



A hearty vote of thanks was accorded Mr. Sutton for his numerous 

 and interesting exhibits. 



Colour in Sweet Pea Tendrils. — At a recent meeting (May 1) Mr. 

 Cuthbertson raised the question of the correlation of the red or green 

 colour of the tendrils in certain varieties of sweet peas with other 

 characters in the plant. He now sent specimens illustrating the possi- 

 bility of the practical utility of attention to this character as an aid in 

 " roguing " in the young stages of growth. A row of the pea ' Captain of 

 the Blues ' was carefully examined some time before flowering, and one 

 plant that differed from all others in having green tendrils instead of red 

 was marked. The flower of the normal ' Captain of the Blues ' has blue 

 wings and a darker standard, while the marked plant was white marbled 

 with blue all over. It is interesting to note that, as Mr. Bateson has 

 previously pointed out, the red colour of the tendrils is usually correlated 

 with a dark spot in the leaf axil, but in this variation the leaf axil 

 possessed the dark spot which is found in all normal specimens of 

 ' Captain of the Blues,' although no trace of red colour was to be seen in 

 the tendrils. Mr. Bateson has shown that the green tendril (hght axil) 

 character is a recessive one, and Mr. Chittenden remarked that while in 

 all the so-called sports of * Countess Spencer ' which he had seen the 

 tendrils were green, and the axils of the leaves devoid of the dark spot, 

 ' Countess Spencer ' itself had red tendrils and dark-axilled leaves. 



Floiuering of Dasylirion glaucophyllum. — The following interesting 

 note was sent by Lady Theodora Guest, of Inwood, Templecombe : — " The 

 Mexican Dasylirion glaucophyllum has thrown up an immense flower 

 stalk in the conservatory here. It has grown some 16 feet in a fort- 

 night, and is now covered with flower buds all up the stalk. A record is 

 preserved of its flowering at Kew in 1857, when it attracted considerable 

 attention, but Lady Guest believes that the flowers have rarely been seen 

 in England." 



The rate of growth recorded shows more than half an inch per hour 

 maintained for a fortnight. 



Axillary Prolification of Cornflower. — Dr. Masters showed a specimen 

 of Centaurea Cyanus from Mr. W. G. Smith, in which flower-bearing 

 branches proceeded from the first-formed flower head somewhat in the 

 manner seen in the * Hen-and-Chickens ' Daisy. 



Diseased Peaches. — Specimens of peach leaves attacked by the shot- 

 like fungus Cercospora circumscissa, came from near Redhill, and shoots
