394 HORTUS MORTOLENSIS 
HARDENBERGIA. 
Very pretty climbers, much planted in the gardens of the 
Riviera. H. monophylla is cultivated in white, rose, and violet 
flowering varieties. It remains much lower than H. Comptoniana. 
HAWoRTHIA. 
A genus of small plants, closely related to Aloe, but with 
small, two-lipped whitish flowers. Most of them do very well 
here, and are excellent plants for rockwork and walls. The soft- 
leaved species, however, prefer half shady places. Some species, 
such as H. cymbifolia, H. granata, H. retusa, and H. subulata, 
were bought from the Jardin d’Essai, Hamma, Algiers, in February, 
1873. Other species were received from the Botanic Gardens of 
Berlin, Kew, Palermo, &c., from Dr. R. Marloth, of Cape Town, 
from Mr. W. J. Skinner, of Thornton Heath, and others. 
HECHTIA. 
Is a genus of decorative xerophilous Bromeliacee. H. argentea 
was received from Mr. Willy Miiller, of Nocera Inferiore, near 
Naples, in 1909. H.glomerata from the Botanic Garden of Ziirich 
in July, 1898. It flowered in 1909. H. rosea (?) was collected for 
Sir Thomas Hanbury by Mr. C. A. Purpus on the Sierra de Parras 
in 1905. It is almost entirely red during summer. 
HEDERA. 
T have followed Mr. C. K. Schneider in the nomenclature of this 
genus. H. canariensis, which now coyers many walls in the 
garden, was first procured from Messrs. Huber & Co., Hyéres, in 
December, 1867. 
HELLEBORUS LIVIDUS. 
Seeds from Corsica were sown by Mr. D. Hanbury in the 
valley, in June 9th, 1868, where still one plant survives. 
HERMANNIA. 
H. angulata, a pretty little shrub with yellow flowers, was 
collected by Dr. J. Brunnthaler near Genadenthal in 1910. 
HESPEROALOE. 
Seeds of both species were received from Prof. Trelease, of the 
Missouri Botanical Garden. 
HESPEROYUCCA. 
H. Whipplei is rightly separated generically from Yucca. It 
dies after having flowered. In its leaves it more resembles Agave 
paucifolia than a Yucca. Several specimens have flowered at La 
Mortola (1891, 1896, 1899 and 1901), but never produced any 
seeds. The plate in Bot. Mag. was drawn by Lady Thiselton-Dyer 
at La Mortola in April, 1891. Seeds were first received from Mr. 
L. Winter, Bordighera, in January, 1882.
