on the island of Guadaloup, off South California, and the latter 

 on the mainland on a very limited area. They appear to be only 

 varieties of one another, the island form being more glaucous, 

 a common feature of maritime plants. Dr. Masters also 

 observed that a variety of Pinus insignis with two "needles" 

 instead of three, the usual number in this species, together with 

 a Fan Palm, Erythea edulis, grew on the same island. 



Calochortus vars. — Mr. Wilson exhibited blossoms showing 

 great variety of colouring in C. venustus citrinus and C. v. 

 oculatus. They were grown in open borders at Weybridge and 

 Wisley. 



Aquilegia and Clematis Hybrids (?). — A communication was 

 received from Mr. E. J. Lowe, of Shirenewton, Chepstow, de- 

 scribing some supposed hybrids, accompanied by specimens of 

 Clematis montana, and a drawing of the " hybrid " Aquilegia 

 exhibited at the last meeting. It was the opinion of the 

 Committee that the evidence of its being a true hybrid was not 

 satisfactorily established. 



Scientific Committee, June 20, 1893. 



Dr. M. T. Masters, F.R.S., in the Chair, and six members 



present. 



Scale on " Retama." — Mr. Morris observed with reference to 

 this subject, brought before the last meeting, that the name of 

 the Retama is Cytisus nubigenus. It is the only ligneous plant 

 growing on a platform at an elevation of 8,000 feet on the Peak 

 of TenerifTe. The whole of the plants were covered with the 

 scale. Dr. Perez had noticed no instance of this scale insect 

 appearing until Australian trees had been introduced into 

 TenerifTe. Mr. Morris added that it has now appeared at Kew 

 on the English Broom. 



Honey dew on Limes. — Mr. Morris remarked that this had 

 been so abundant on the Limes at Kew that the cement pave- 

 ment below them had become quite slippery from the drip from 

 the trees. Mr. Henslow added that he remembered a similar 

 occurrence from an Ash-tree in a garden in Regent's Park Road 

 about the year 1878. 



Oranges in Devon.— -Mr. Morris exhibited photographs of
