earmin sur les bords interieux des petales lateraux." The anterior 

 sepal of I. comorensis is white, and of I. auricoma yellow, while in the 

 hybrid it is yellow striped in the lower part with carmine. A table 

 comparing the hybrid with its parent is given along with an account 

 of the raising of the hybrid in the Revue Horticole, September, 1908, 

 pp. 427-428 (see below). 



Uncommon Conifers. — From Sir Edmund Loder, Bart., Leonardslee, 

 came branches with cones of Larix Griffithii and L. americana. 



Scientific Committee, June 8, 1909. 



Mr. E. A. Bowles, M.A., F.L.S., F.E.S., in the Chair and eighteen 



members present, 



Impatiens x comoricoma. — The award of a Certificate of Appreciation 

 was unanimously recommended to Messrs. Cayeux in acknowledgment of 

 work done in raising the hybrid Impatiens shown at the last meeting, 

 and the careful notes thereon contained in the Revue Horticole. 



Hybrid Dianthus. — Mr. Douglas, V.M.H., exhibited flowers of hybrid 

 Dianthus. One had been raised by crossing Dianthus barbatus with a 

 double pink (D. plumarius). This had rather glaucous foliage, leaves 

 about fin. broad, and pink flowers with about a dozen petals laciniated at 

 the margins, borne on branched stems carrying about eight or ten flowers. 

 The second was the hybrid between D. barbatus and D. Caryophyllus 

 var. 1 Uriah Pike,' known as ' Lady Dixon,' a form which never produces 

 seeds but flowers very profusely. 



Variegated Laurel. — Mr. Crawshay showed foliage of a much 

 variegated form of the common laurel, Prunus Laurocerasus. The 

 bush from which this was cut was an old one, and the variegation had 

 proved constant. 



Alpine plants. — Mr. Fraser, F.L.S., showed cultivated specimens of a 

 very dwarf form of Salix herbacea which he had collected at an elevation 

 of 3,984 feet on Ben Lawers. The height to which it attained in the 

 wind-swept situation in which it was growing was only from J inch to 

 \ inch. He also showed Draba rupestris from the same locality, and 

 Tofieldia palustris from an altitude of 2,800 feet in Perthshire, with fruit. 

 These had all been grown in pots, and were somewhat taller than when 

 collected. Mr. Fraser also showed flowers of Rosa spinosissima, which is 

 still found growing wild within the county of London, though it does not 

 now fruit. The flowers exhibited were very small, and had been picked 

 from a wild specimen. 



Lonicera Standisliii. — Mr. Holmes, F.L.S., exhibited ripe fruit of this 

 Lonicera, which rarely fruits in Britain. 



Aquilegia double. — Mr. Hales drew attention to the doubling of 

 Aquilegias where, somewhat as in the hose-in-hose primrose, the petals 

 are packed one within the other. Mr. Chittenden pointed out that the 

 additional petals were modified stamens, of which the filament became 

 the claw of the petal, while the spur and the limb of the petal were 

 developed from the anther ; in specimens in which the modification had
