XC PROCEEDINGS OF THE ROYAL HORTICULTURAL SOCIETY 



SCIENTIFIC COMMITTEE. 



May 13, 1919. 



Present : Mr. E. A. Bowles, M.A., F.L.S., V.M.H., in the Chair, and five 



members present. 



Certificate of Appreciation. — A Certificate of Appreciation was nanimously 

 recommended, at the instance of the Orchid Committee, to Messrs. McBean of 

 Cooksbridge for work done in raising the interesting hybrid Odontoglossum X 

 Eugenia. This plant is the result of crossing O. cordatum and O. crispum. Its 

 flowers are nearest to O. crispum, but the segments are narrowed by the influence 

 of 0. cordatum, the dull red blotching of which is also shown. The labeilum 

 has undergone a curious change, its form being broadly ovate, the acuminate 

 apex of the cordate labeilum of O. cordatum being suppressed, the only evidence 

 of it being seen in a short thread-like apiculus on the under side of the front of 

 the lip. 



Fasciatcd Saxifrage. — A fasciated stem of Saxijraga hypnoides was sent by 

 Mr. Britten of Cuckfield. The stem was fully half an inch in width and bore 

 numerous rather small flowers. 



Hybrid Buddleia. — Mr. Van de Weyer sent a specimen of the hybrid Buddleia 

 globosa X B. madagascariensis which he had raised in his garden at Corfe Castle. 

 While B. madagascariensis is only half hardy at Corfe Castle, the hybrid is growing 

 outdoors and flowers earlier than B. globosa. It has no scent, as in B. madagas- 

 cariensis, the leaves of which it has also inherited, there being none of the tawny 

 down on the leaves as there is in B. globosa, but in the manner of flowering it has 

 followed B. globosa, though the flowers are on the whole paler and the balls of 

 flowers rather larger. 



Scientific Committee, May 20, 191 9. 

 Mr. E. A. Bowles, M.A., V.M.H., in the Chair, and seven members present. 



Chinese plants. — Mr. Bowles showed a Spiraea with gay foliage and with some- 

 thing of the flowering habit of S. arguta, but quite distinct. He also showed Mr. 

 Farrer's fern of Lonicera syringantha, a larger- flowered fern than is usually grown. 

 These had both been grown by Mr. Morris at Earlham. 



Kale with foliar enations. — Mr. Bowles showed foliage of a Kale with many 

 enations from the leaves, and these crisped at their edges, so that quite a frill was 

 produced. 



Certificate of Appreciation. — The Council had before them plants exhibited, 

 and awarded Certificates of Appreciation to Mr. Magor of Lamellan for work in 

 raising Rhododendron X lepidoboothii (lepidotum X Boothii), to Mr. Dykes for 

 raising Iris stolonifera X Kotolkowii, and to Miss Brennand for her paintings of 

 Rhododendrons. 



Populus lasiocarpa. — A catkin was shown with developing fruits on the 

 same catkin with staminate flowers in lower part, from Mr. C. J. Lucas. 



Scientific Committee, May 27, 1919- 



Mr. E. A. Bowles, M.A., in the Chair, with three members present, and 

 Mr. G. Marsden Jones, visitor. 



Hybrid Geums. — Mr. Marsden Jones showed a hybrid between Geum sibiricum 

 and G. bulgaricum (large-leaved form). The hybrid followed G. sibiricum in the 

 main, but had the viscid hairs of bulgaricum. Hybrids between G. rivale form 

 and G. coccineum had leaves mainly of the rivale type and open flowers, with 

 colours varying from orange to purplish orange. Eight distinct forms, one of 

 them more or less inclined to doublencss, were found. Gcum bulgaricum had 

 also been crossed with Geum coccineum, and had given a form with foliage near 

 that of bulgaiicum and attractive flowers. This was a particularly interesting
