which are not acutely keeled. The flowers are very variable in colour, 

 and this variability has given rise to numerous synonyms — e.g> 

 1. italica (Pari.), I. lutescens (Lam.), 1. Olbiensis (Henon), and 

 /. virescens (Delarb.) A Certificate of Appreciation was unanimously 

 awarded to Mr. Dykes. 



Hyacinth with Violet and Magenta Flowers on the same Stem. — 

 This specimen showed a case of " dissociation " of colours. It was 

 remarkable for having the flowers on one half of the scape — i.e. from 

 bottom to top — violet, the other half being a rose-tinted magenta. The 

 arrangement of the vascular bundles of the stem did not indicate any 

 signs of a fusion between two stems. Moreover, the phyllotaxis was 

 continuous, thus also indicating a single inflorescence. The epidermis 

 was of a purplish-green colour down one half of the stem which bore 

 the violet flowers, that of the other half was pale green. All the flowers 

 issuing from the former side were of a dark-violet colour, and all from 

 the latter a rose-magenta. A few along the lines of junction were parti- 

 coloured; some flowers had one or more lobes of the perianth of one 

 colour, the remainder being of the other. The lobes of some were 

 divided down the middle half, a lobe being of each colour. The rose- 

 magenta flowers varied in having six to eight lobes, the entire flower 

 being smaller than the violet ones. It would appear, therefore, that 

 in one half of the flowers blue was largely wanting. Comparing the 

 colours with a standard list, magenta is recorded as having forty-five 

 parts red to forty-nine blue, while violet has twenty-one red and sixty- 

 nine blue ; so that the blue element is greatly suppressed in the magenta 

 but present in the " rose " tint. Under electric light when blue is 

 absorbed the violet flowers appear grey and the rose-magenta a pure 

 red. 



Hybrid Pelargoniums. — Mr. A. Langley-Smith, of Catford, showed 

 hybrid pelargoniums as follows : — 



Hybrid Pelargonium ' Cataract ' (P. Radula minor x P. denticu- 

 latum, ' Pheasant's Foot ') has the finely cut leaf of P. Radula, with 

 the scent of P. denticulatum.. When grown in poor soil it can only be 

 distinguished from P. Radula by the scent. In good soil, however, the 

 growth is rampant, the leaves are very large, and the tips curl over. 

 Hence the name chosen. The bloom is almost identical with that of 



j P. Radula, and the plant is, like its seed-parent, apparently self-sterile. 



1 Hybrid Pelargonium ' Jonathan Smith ' (P. denticulatum, x P. 



j seedling IS) resembles P. denticulatum in leaf and scent, though the 



|: leaf is somewhat blunter, lighter in colour, and more leathery. In 

 habit and in shape and colour of bloom it resembles the pollen-parent, 

 the blooms under good cultivation being perfectly circular, and it is 

 heavily blotched with maroon on the two upper petals. The plant is 

 sterile. 



Hybrid Pelargonium ' Patience ' (P. tomentosum x P. filicifolium 

 var. ii.). — A perfect blend of the characteristics of the two parents, 

 ' having the hoariness of P. toment^osum, with leaf and bloom halfway 

 between the two in shape, size, and colour, and a compound scent in
