22 Descriptions of Plants belonging to the Genus Hoya, 



The property of attracting wasps and other insects, even 

 when ripe fruits are present, has been attributed to the 

 blossoms of Hoya carnosa, by Mr. John Maher, in a com- 

 munication* to the Horticultural Society, in the year 1815. 

 This however appears to have been doubted by Sir Thomas 

 Frankland, when writing -f on the subject in 1820, and 

 subsequent experience has confirmed his suspicions of the 

 accuracy of the fact thus stated by Mr. Maher. The 

 flowers when in perfection do not appear to be particularly 

 visited by any of the insects which find their way into the 

 houses where the Hoyas are cultivated.

 I add the reference. 



Hoya crassifolia. Haworth in Supp. Plant. Succ. p. 8. 



A plant of this species was sent to Mr. Reginald Whit- 

 ley, from China, in 1817, on board the Wexford East 

 Indiaman, and has since been cultivated and increased in his 

 nursery at Fulham.J It is very distinct from, and of much 

 more robust growth than, any of the others. The stems are 

 strong and woody, thickly covered with small irregular warts, 

 whence the stem -roots are protruded. The leaves are 

 obovate, very bluntly acuminate, upwards of four inches 

 long, without veins, of a darkish green colour above, pale 

 beneath. The petioles are thick and fleshy, of a purplish green 

 colour, and much flattened above. The plant grows freely
