HETEROMORPHA ARBORESCENS. 
A tall bush ora small tree with the bark similar to birch trees; 
flowers and fruits abundantly. The seeds were sent by Mr. D. 
Hanbury in November, 1870, who probably received them from 
Prof. MacOwan. 
HIsIscus. 
H. venustus var. rosews was received through the kindness of 
Prof. C. F. Baker from Santiago de las Vegas, in Cuba, April, 1906. 
It is a large bush, which flowered in December, 1907, and which 
differs from the typical H. venustws in the colour of its flowers. 
HoLLB@LLIA LATIFOLIA. 
Flowers abundantly, but has never set fruit, not even when 
artificially impollinated. 
Hoop1a CuRRORI. 
Was received several times from Mr. Dinter and from Messrs. 
Haage & Schmidt, but always perished during our often wet and 
cold winter months. 
HoveENIA DULCIS. 
Is much planted in the Far East for its edible fleshy fruit 
stalks. Our oldest plant was procured from Hyéres in December, 
1867. 
HowEa. 
H. Belmoreana and H. Forsteriana, better known in gardens 
under the name of Kentia, do not do well at La Mortola, but grow 
to perfection in other places on the Riviera, for instance, in some 
gardens at Garavan (Villa Hindoue, Villa Paradu, Villa St. Louis, 
&e.). The genus differs chiefly from Kentia in having a simple un- 
branched spadix, 30-40 stamens in the male flower, and different 
seeds ; in habit the plants of the two genera resemble each other 
a good deal. 
The two species are very closely related, and Bentham does 
not regard them as specifically distinct. H. Belmoreana, the 
“ Curly Palm,” is said to attain 12 m. in height, with leaves over 
2m. long, the numerous acuminate leaflets of which converge 
towards the apex. A. Forsteriana, the “Thatch or Flat Leaved 
Palm,’” closely resembles the former, but has the leaflet always 
pendulous. 
Hoya CARNOSA. 
Ts quite hardy in sheltered places, and is therefore frequently 
planted. It flowers abundantly, but never fruits. 
HYMENOSPORUM FLAVUM. 
Seeds were sent by Mr. D. Hanbury in June, 1872, and probably 
received from Baron Ferdinand von Miiller, of Melbourne. It is 
a tree similar in habit and flowers to Pittosporwm, but the seeds 
are very thin (hence the name), and not viscous as are those of 
Pittosporum. The flowers are at first white, but after the pollen 
has been shed and the stigma matures they become yellow Our
