1 PROCEEDINGS OF THE ROYAL HORTICULTURAL SOCIETY. 



Cattleya Laiure7iceana, Malformed. — Mr. O'Brien showed a flower 

 devoid of a labellum, also C. Mendeli, which often comes deformed, and 

 more or less constantly so in plants from certain areas. Mr. Douglas 

 observed that he had a plant with fifteen flowers, dimerous, or lipless, kc. 



Crinum sp. — Mr. Elwes exhibited plants of Crinum which flowered 

 after fifteen years. They came from near Lake Nyassa, and there was a 

 doubt as to their specific differences from G. capcnse, as there was great 

 variability among plants from seeds. G. crassifolium (according to Dutch 

 growers) appeared to be the same as G. petiolatum from the Niger, 

 remarkable for its globular bulb, and by continuously flowering. 



Plants from Gambridge Botanic Gardens. — Mr. Lynch exhibited the 

 following interesting plants : — Dimorphotheca fruticosa, only lately intro- 

 duced to Cambridge from S. Africa ; Lathrcea clandestina, with large 

 purple flowers, which Mr. Lynch has succeeded in establishing on the 

 roots of Willows, as well as our native L. squamaria on Poplars ; Hippc- 

 astrum aulicum, one of the species of the original hybrids of the modern 

 so-called Amaryllis, remarkable for the great obliquity of the perianth 

 leaves ; Gheirantliiis mutahilis, the true plant, and not the same as that 

 usually grown under this name ; it is not quite hardy. Prof. Church 

 remarked that specimens grown at Kew show a larger range of colours 

 than those of the Cambridge plants, and that the peculiar nature of the 

 colouring matters is due to changes in the neutrality, alkalinity, or 

 acidity of the sap. Acer carpinifolium. — This is one of the several Japanese 

 species, having leaves without lobes, the blade closely resembling that of 

 the Hornbeam. Hekvingia japonica. — The foliage is remarkable for 

 having the peduncles adherent to the petiole (as is that of the Lime to 

 the bract), so that they are apparently borne by the leaf, and resemble 

 superficially Buscus aculeatus. Gitrus trifoliata, a very spinescent 

 species, requires only a very slight protection. Dr. Masters observed that 

 it was used in Florida as a stock for Oranges, so that they could with- 

 stand frost. Hymcnanthera crassifolia, a shrub both in flower and fruit 

 of the family Violace^B. It is a native of New Zealand. Hibbertia 

 scandens, perhaps the largest flowering species, somewhat resembling 

 Hypericum calycinum, while H. lieadi bore the smallest flowers ; probably 

 natives of Australia. Stigmaphyllon ciliatum, a handsome, yellow- 

 flowered Malpighiad. Macleania insignis, of the order Vacciniacefe, a 

 very uncommon plant, figured from the Cambridge plant in Bot. Mag. 

 t. 7694 (1900).
