CROWEA LATIFOLIA, &c. 225 
Monnieeia, Spiranthera, and Ticorea. — The first has only one species, trifolia, 
a white-flowering annual of no beauty, discovered in Guiana and Brazil, requiring 
the common treatment of tender annuals. For the culture of Spiranthera odora- 
tissima, refer to Galipea. Seven species of Ticorea are described, and two of them 
are now not uncommon in our stoves. T. fwtida and T. jasminiflora are both 
deserving of cultivation; in their native countries, Guiana and Brazil, they are 
reputed to possess fine medicinal properties. Neither of them emit a pleasant 
fragrance, but, especially the former, is very disagreeable when the leaves are 
bruised. 
The cultivation of Ticorea differs in nothing from that recommended for Galipea, 
except that less shading is required, and in propagation ripened cuttings are used, 
instead of being only little more than half ripe, as there recommended. 
The above eight genera constitute the First Group or Tribe Cusparlele, from 
their agreement, in several important characters, with Galipea Cusparia, the type 
of the old genus Cusparia. 
Choisya — temata is the only species known, and is a beautiful evergreen shrub, 
growing from six to eight feet high. It was found in the dense woods of Mexico, 
and was introduced in 1825. Its culture is the same as Galipea. 
Esenbeckia. — Two species, E. febrifuga and pilocarpoides, have been described, 
and probably both have been introduced. The culture is the same as Galipea, 
except that the cuttings are made of the young, instead of ripened wood. 
Evodia. — This genus, which contains three species, require exactly the treatment 
of Esenbeckia. 
Geigera, Hortia, Melicope, Metrodorea, and Pilocarpus, form the Second 
Group, called Pilocarpe^e. All these are treated alike in cultivation, and are well 
deserving of a place in the stove. 
Tribe 3 — Boronie^e — is composed of plants from the neighbourhood of Australia. 
Some are old and well-known inhabitants of our greenhouses, as the species of 
Boronia — " Magazine of Botany," vol. i., t. 173 ; vol. iv., t. 267 ; vol. viii., t. 123 ; 
vol. ix., t. 123 — and Corr^a — " Magazine of Botany," vol. vii., t. 79 and 195 ; 
vol. ix., t. 267 ; and the present volume, t. 147. Others, however, are less known, 
although some of them have been many years in the country, as Crowea, the subject 
of the present plate, Chorilcena, Cyanothamnus, Diplolcena, Didymeria, Eriostemon, 
Hugelia, Phebalium, Philotheca, and Zieria. 
The whole of these genera require, with a few exceptions, the same kind of 
treatment in culture. These exceptions arise from the difference in structure and 
hardihood of the various species. Some of them are very beautiful, and indeed the 
greater part deserve extensive cultivation. The two species of Diplolcena, it is true,
