Scientific Committee, June 4, 1912, 



Mr. E. A. Bowles, M.A., F.L.S., F.E.S., in the Chair, with fourteen 

 members present and Mr. J. A. Alexander, visitor. 



Odontioda x * Carmen.'— Mr. de Barri Crawshay sent this hybrid 

 between Cochlioda Noezliana and Odontoglossum nebulosum showing 

 characteristics of both parents. Hybrids with the latter plant as one 

 of the parents are scarce, and a Certificate of Appreciation was 

 unanimously recommended to Mr. Crawshay. 



Afzelia quanzensis. — Mr. Holmes, F.L.S., showed a pod and seeds 

 of this African tree, the seeds of which are half-black, half-scarlet. 



Botanical Certificates. — ^Professor I. Bayley Balfour exhibited the 

 following new or uncommon plants: Oxytropis y unnanensis Franchet, 

 (bearing deep-blue flowers), Saxifraga majuscula (very closely allied to 

 S. Brunoniana, but much larger in all its parts), S. diversifolia var. 

 foliata with marked veining of the ovate leaves, Primula x * Edina * 

 (which received a Botanicah Certificate at the last meeting), Senecio 

 Lyallii, Hook f. (with yellow flowers about 1^ inch across, from New 

 Zealand); Aster likiangensis Franchet (with large, deep-blue flowers 

 about 2 inches in diameter on stalks 3 inches long,- from Yunnan, a 

 very beautiful little plant) ; Primula x * Inverleith ' (P. Bulleyana x 

 P. pulverulenta), a plant much in the way of P. x ' Edina,' but a 

 shade deeper in colour and more robust in habit. Botanical Certificates 

 were unanimously recommended for the last three plants. 



Variation in Sweet Peas. — Mr. Cuthbertson brought examples of 

 Sweet Peas, which he thought showed reversion to original forms. 

 (1) A rich ruby- coloured unnamed variety produced waved flowers on 

 normal plants, i.e.,^ plants having waved leaves. Two plants of the 

 same variety with perfectly plaint leaves, like the leaves of the old type, 

 had produced perfectly waved flowers with open keels. (2) In the white 

 waved variety (' Etta Dyke '), in the waved cream variety (' Dobbie's 

 Cream '), and in the pink-and-white bicolor (' Mrs. Cuthbertson') he 

 had found deep purple-flowered plants — one in a thousand, perhaps- 

 giving a colour approaching the colour of the wild Sweet Pea, but retain- 

 ing the waved formation. 



Sweet Pea with leafy tendrils.- — ^^Mr. Cuthbertson also showed some 

 Sweet Pea leaves with some of the tendrils becoming leafy, the result of 

 high cultivation. , 



Scientific Committee, June 1,8, 1912. 

 Mr. J. W. Odell in the Chair, and eight members present. 



Pseudohulbs in Inflorescence. — Mr. O'Brien, V.M.H., drew atten- 

 tion to a plant of Oncidium ahortivum (or 0. heterantheum) shown by 

 Sir Trevor Lawrence, K.C.M.G., V.M.H., bearing on the many- 

 flowered inflorescence some well-developed pseudobulbs, each with two 

 or three flowers. 



Thelymitra sp. — A terrestrial orchid from Tasmania was also shown
