with yellow markings on all segments ; no purple. (10) Yellow with 

 red-brown blotches except in lower half of lip. Odontioda x 

 ' Brunette ' is the result of crossing Odontioda x Bohnhoffiae (Odonto- 

 glossum cirrhosum x Cochlioda vulcanica) with Odontoglossum 

 Harry anum. 



Mr. R. A. Rolfe, A.L.S., showed a series of flowers of Cymbidium 

 X ' Butterfly ' {Lowio-grandiflorum x insigne) from the collection 

 of Lieut. -Colonel Sir George L. Holford, Westonbirt, Tetbury. The 

 flowers were from the same seed-pod and comprised eight forms — 

 one cream, one light yellow, and six various shades of rose-pink in 

 the segments, while the lips showed much variation in the amount of 

 spotting. 



Gooseberry diseased. — Mr. E. M. Holmes, F.L.S., showed a shoot 

 of Gooseberry with the black pycnidia of a species of Coniothyrium 

 upon it, which he believed to be C. ribicolum, a species found upon 

 Currants. 



Leucojum Vagneri. — Mr. W. H. B. Fletcher, of Aldwick Manor, 

 Bognor, sent a number of flowers of this fine form of Snow^ake, which 

 is rarely seen or mentioned. Most of the scapes bore five or six 

 flowers and many of the flowers were more or less abnormal in some 

 degree, perhaps due to the vigour of the plants, which had been in 

 his garden for about fourteen or fifteen years. (Fig. 51). 



New Fungus in Scale Insects. — Dr. A. S. Home showed specimens, 

 with respect to which he made the following communication : " In 

 December 1914, Professor Lefroy brought to my notice some Centro- 

 pogons heavily infested with the greenhouse white fly, Aleyrodes 

 vaporariorum. The leaves were covered on their under surface with 

 tufts of fungus mycelium. One of the fungi present proved to be a 

 species of Cladosporium, which acts by investing the almost 

 permanently-attached scale and apparently closes the tracheae ; 

 another is a species of the genus Cephalosporinm, which resembles in 

 mode of occurrence but is specifically distinct from the entomogenous 

 Cephalosporinm Lecanii, discovered by Zimmermann in Java (1898), 

 afterwards found in the West Indies by H. M. Lefroy (1902), and 

 subsequently used to combat the Brown Shield Scale (Saissetia hemi- 

 sphaerica) and other West Indian pests. This Cephalosporinm appears 

 to differ in important characters from those already described." 



Large Cytisus. — Mr. T. O. Walker, of Annas Bank, Carnforth, 

 sent a section cut through the stem of Cytisus Andreanus in his garden. 

 The section was not circular, but eccentric, as the S.W. side had 

 died about three years ago. The thickest part of the stem, just about 

 ground level, was 19 inches in circumference, while the bush, which 

 was ten or eleven years from seed, was 11 or 12 feet high, and as much 

 through. 



Primula silvicola. — Messrs. Wallace, of Colchester, showed a new 

 Primula raised from seed collected by Forrest in Western China, and 

 named P. silvicola by Prof. Balfour. It belongs to the same group 

 as the Himalayan P. mollis, and has large, rounded, petiolate, hairy
