392 HORTUS MORTOLENSIS 
native land it is said to reach 13 m. (= 40 feet), and not to 
flower before having attained the age of four hundred years (?) 
With us it seems to flower after twenty to thirty-five years, but 
there may be two species in question. Our plant, received from 
Kew in 1881, is no doubt the species figured in Bot. Mag. t. 5519, 
which flowered in Regent’s Park Royal Botanic Garden, in 1864, 
for the first time in Europe. 
GARRYA THURETI. 
Was received from Villa Thuret in 1903; it has not yet flowered. 
It is not included in Mr. Wangerin’s monograph in BR. V. C. 
GASTERIA. 
G. acinacifolia and others were bought from the Jardin 
d’Essai, Hamma, Algiers, in February, 1873. Gasterias easily 
hybridize in gardens, and there are various forms of doubtful ori- 
gin. See my notes about them in my monograph on Aloinea, l.¢. 
GAZANIA. 
Of these wonderful spring flowers the following garden forms 
were sent by Cav. C. Sprenger, Naples :—G. angelica, G. elmen- 
sis, G. ochroleuca, G. Parthenope, G. splendens, G. Trinacria, 
G. vomerensis. 
GERBERA JAMESONI. 
Was first received from Kew in October, 1890. It is not 
satisfactory at La Mortola. 
GIRALDIA STAPFII. 
Received from Cav. C. Sprenger, October, 1901; is a small 
perennial plant resembling Atractylis, with which the genus ought 
perhaps to be united. 
GLEDITSCHIA MACRACANTHA. 
This tree was for a long time in cultivation in the garden 
under the wrong name of G. caspica. Dr. A. Henry recognized 
it as the plant which he collected in South Wushan, Szechuen, 
and which was described as G. officinalis Hemsl. in Kew Bull. 
1892, p. 82. The pods are the Chinese drug exported from the 
province of Szechuen under the name of “‘ Ya-tsao.”” These pods 
were described by Mr. Daniel Hanbury in his ‘‘ Notes on Chinese 
Materia Medica” (Legumes of Prosopis? D. Hanbury, Science 
Papers, p. 248). 
GNIDIA. 
These small shrubs succeed well on sandy banks in the upper 
part of the garden. We received them from Mr. F. Rehnelt, of 
the Botanical Garden at Giessen. 
GOODENIA OVATA. 
We owe this interesting shrub to the kindness of the late 
Mr. L. van den Bossche, Tirlemont. It is our only plant of the 
Goodentacee.
