120 FLORULA HONGKONGENSIS. 
a tree in the Happy Valley woods. It blossoms at least twice in a 
year. It appears also to be frequent about Macao and Canton, from 
whence we know of no other species, and fully agree with Hooker and 
Amott, in considering the two published by Lindley as one and the 
same. It differs, however, in several essential points from Loureiro's 
character of Pythagorea, but coincides exactly with that of Astranthus 
of the same author, and on this account I had given to the plant the 
name of B. Loureiri, thinking that Lindley’s plant might be different. 
Loureiro’s plants are, however, both Cochin-Chinese, they are both pro- 
bably Homalinee, but without seeing original specimens, or at any rate : 
specimens from the same country, it would be difficult to identify them 
satisfactorily. The confusion of synonymy has been, unfortunately, 
much increased by errors in copying or printing, for I can trace no other 
origin to the names of B. Chinensis, grandiflora, and padifolia attributed 
to Lindley by Steudel, and that of pubiflora, Lindl., inserted in Walpers’ 
Repertorium. 
The flowers of this species have the perfume of our hawthorn. After 
they wither the perianth remains some time attached to the ovary, and 
the lobes become slightly enlarged. They vary in number from six to 
nine pair. The styles and placentæ are two, three, or four, with three 
ovules to each placenta. The fruit has not been observed.
