PROCEEDINGS OF THE ROYAL HORTICULTURAL SOCIETY. 



specimens were received from Mr. Frank Lloyd, of Coombe 

 House, near Croydon. 



Carnation Leaves malformed. — Mr. Douglas exhibited leaves 

 with peculiar horn-like excrescences on the margins. It was 

 suggested that they might be caused by acari. They were 

 forwarded to Dr. Michael for investigation. Dr. Masters observed 

 that a Yucca in the Botanic Gardens, Dublin, produced very 

 similar structures every year. 



Malformed Cauliflower. — Mr. Henslow exhibited a stalk 

 bearing a cluster of short Asparagus-like shoots, the leaves being 

 reduced to a bracteate form, suggestive of the name of Broccoli — 

 viz. Brassica oleracea var. Botrytis asparagoides. Dr. Masters 

 observed that it bore a very unusual appearance, really inter- 

 mediate between a Cauliflower and a Wild Cabbage. 



Scientific Committee, November 9, 1897. 

 Dr. Masters, F.R.S., in the Chair, and five members present. 



Cattleya labiata, Sport. — Dr. Masters observed that sports 

 similar to those produced at the last meeting, in which two 

 sepals were more or less resembling the labellum, had been 

 sent to him from numerous localities this year. The species 

 was introduced some fifty years ago, and subsequently lost ; 

 but it had been lately rediscovered in and introduced from 

 Pernambuco. 



Carnation Leaves with Horn-like Marginal Outgroivths. — 

 Mr. Michael reported that no trace of acari could be seen, as 

 suggested as a possible cause. Dr. Miiller observed that a plant 

 of Solatium jasminoides was covered all over with horn-like 

 excrescences. Dr. Masters suggested that they were probably 

 spongy outgrowths from the epidermis. 



Stocks, dx., attacked by Beetles. — Mr. Michael observed 

 that Stocks, Virginia Stocks, and Nasturtiums in his garden 

 were attacked and utterly spoilt in a fortnight by thousands 

 of beetles eating the flowers of the two former plants, but 

 the leaves as well of the last named. They do not entirely 

 kill the plants, which renew both leaves and flowers after the 

 beetles have disappeared. A partial remedy was found in 

 shaking the plants over a basin of hot water. It appears to
