Though fasciated plants are very frequently shown before the Com- 

 mittee, perhaps more frequently than those showing any other aberra- 

 tion of growth, Stocks have rarely or never been exhibited in this 

 condition. The present specimen was growing on the cliff outside 

 an hotel garden, and others there showed a similar habit of growth. 



Locusts and Coconuts. — Mr. Gilliat sent a note concerning the 

 destruction of seedling coconuts over an area of 500 acres in the 

 Federated Malay States, where the trouble from this pest has recurred 

 in a second year. The use of paraffin had proved unsuccessful in 

 abating the trouble, and it was suggested that Paris green or lead 

 arseniate should be tried, either as a spray or by drenching some locusts, 

 collected and slightly crushed beforehand, with this poison. Some 

 species of locust are cannibals, and it might be possible to check their 

 ravages by collecting and poisoning some of them in this way. 



Malformation in double Primula. — Dr. J. Mac Watt sent a curious 

 flower from a double Primrose seedling ; the calyx was much larger 

 than usual, and had double the usual number of teeth. It surrounded 

 two separate and distinct double corollas, separately inserted on 

 the receptacle and normal in every other respect. 



Scientific Committee, April 15, 1913. 

 Mr. G. Gordon, V.M.H., in the Chair, and six members present. 



Hose-in-Hose Polyanthus. — Mrs. Berkeley, of Spetchley Park, 

 Worcester, sent Polyanthuses of the hose-in-hose type in which the 

 calyx segments are exactly similar to those of the corolla. 



Delayed Flowering of Amaryllis Belladonna. — Mr. Odell referred to 

 the failure of Amaryllis Belladonna to produce flowers in the past 

 autumn, and stated that the aborted flowers were now being developed. 

 Mr. Worsley stated that the same thing had happened in his garden 

 after wet summers. It may be noted that A. Belladonna flowers in 

 January at the Cape just after the leaves begin to go off. It may 

 occasionally flower a second time in June. 



Odontioda x Patricia. — Mr. Rolfe, A.L.S., exhibited paintings and 

 flowers of five seedlings obtained by Messrs. Charlesworth from 

 Odontioda Charlesworthii (Cochlioda Noezliana x Odontoglossum 

 Harryahum) crossed by Odontoglossum x 1 Phcebe ' (0. cirrhosum x 0. 

 crispum), and showing a remarkable range of colour variation from 

 the same capsule. Two were of a peculiar shade of dark claret-red, 

 and another brilliant orange-brown, these being self-coloured except 

 for a little yellow on the lip. A fourth was yellow with large transverse 

 red blotches, and a fifth claret-purple with a darker mottling. The 

 differences in shape were not great except in the lip, the fourth being 

 most like the Odontioda parent, and the others more deltoid, as in 

 the Odontoglossum. Flowers of both parents were also shown. 



Epidendrum x kewense. — Mr. Rolfe also showed a series of paintings 

 of E. x kewense with its parents and offspring. The bright yellow 

 E. xanthinum crossed with the deep purple E. evectum gave the salmon-
