SCIENTIFIC COMMITTEE.

Paris green was resorted to with success, but lead arseniate was used 

 without benefit. 



Alstroemeria Hookeri. — Mr. DuCane Godman sent flowers of an 

 Alstroemeria which was introduced some years ago from Chile by Mr. 

 H. J. Elwes, but which had not hitherto been identified. The flowers 

 were identical in form and arrangement with those figured in Loddiges' 

 Botanical Cabinet, No. 1272, under the name Alstroemeria Hookeri. The 

 plant there figured was stated to be nearly 2 feet in height, but the 

 present one rarely exceeded i foot. 



Lysionotus Willmottiae. — This species of Lysionotus, shown at the 

 Holland House Show and recommended by the Floral Committee for 

 a Botanical Certificate, was introduced by Mr. E. H. Wilson as Lysiono- 

 tus sp. No. 370. The plant is a dwarf shrub belonging to the Gesneraceae, 

 and has Pentstemon-like flowers measuring if inch long and hlac 

 blue. The leaves are ovate-lanceolate. The award of a Botanical 

 Certificate was confirmed, subject to the name being a valid one. 

 [No technical description of a plant under this name has apparently 

 been published and the Certificate was, therefore, not awarded.] 



Fruit of Harpagophytum. — Sir John T. D. Llewelyn showed a fruit 

 of H. procumbens, a native of S. Africa, and known there as the Grapple 

 Plant. He also exhibited a plant of Primula pseudocapitata, and made 

 some remarks upon the change which had followed the cultivation of 

 the plant known to gardens as P. capitata. P. capitata of gardens 

 appears to be perennial if the seeds are removed, though if they be 

 permitted to fruit the plant dies. 



Cladrastis amurensis. — Mr. J. Fraser, F.L.S., showed spikes of flowers 

 of this Cladrastis, which, although introduced in 1880, is still rare. 



Orobanche Hederae. — Mr. E. M. Holmes, F.L.S., said that two years 

 ago he cut down an Ivy on the roots of which Orobanche Hederae was 

 growing. This parasite still appeared in the same place, although no 

 part of the aerial portion of the Ivy remained. 



Nemesia with fringed flowers. — The Rev. W. Wyley, of Aysgarth, 

 sent specimens of Nemesia to illustrate the following note : — " About 

 the year 1905 the raiser had a bed of Nemesia Suttonii (large-flowered), 

 bordered with N. strumosa (?) (dwarf), and, hoping to get a strain of 

 blue Suttonii, endeavoured to fertilize white Suttonii With, hhie strumosa 

 pollen ; but having too little spare time and losing many seedlings 

 through slugs, he mingled the seed of the resultant plants in 1906 with 

 that gathered from N. Suttonii. During the next five years the frequent 

 occurrence of an intermediate type (flower smaller and narrower than 

 A^. Suttonii) was noticed, one of which in 1910 had fringed upper 

 petals (flowers white). In 1911 two such specimens occurred (one 

 white, one yellow), which he interpollenized with the dark-coloured 

 N. Suttonii. In 1912 again many seedlings were destroyed, but there 

 appeared three of intermediate fringed type (one white, one yellow) 

 and two of Suttonii type (a little small, but more heavily fringed, one 

 crimson, one orange mottled). All these he interpollenized, and in 

 1913 about ten per cent, were heavily fringed, of various colours,
