STAPHYLEACEÆ. 
1. Eyrea vernalis, Champ.* — Staphylea simplicifolia, Gardn. et 
Champ. in Kew Journ. Bot. vol. i. p. 309. 
Not uneommon in ravines on Mount Victoria and Mount Gough, 
forming a shrub of three to four feet in height, in flower in March and 
April, and in fruit in October. There are two, if not three varieties of 
it, with broader or narrower leaves, and flowers a dirty white or purplish, 
especially when in bud. 
Notwithstanding the similarity of the flowers of this plant to those 
of Staphylea, yet the general habit of the plant, its leaves always simple, 
its erect trichotomous inflorescence, and the fruit (observed by Captain 
Champion since Dr. Gardner's description was written), are so distinct, 
that we cannot any longer retain it in that genus. Dr. Gardner's 
description of the ovary is also rather a theoretical one than that of its 
actual appearance, for the carpels are completely combined into a single 
three-celled ovary, with a simple style, of which even the stigmatic 
apex is scarcely lobed. We, therefore, now propose it as a separate - 
genus, under the above name of Zyrez, with the following character :— 
Flores hermaphroditi. > Sepala 5, decidua, æstivatione valde imbricata, 
2 exteriora minora. Petala 5, sub disco hypogyno integro v. sub- __ 
* This new genus is named by Captain Champion in honour of his friend Colonel - 
Eyre, lately returned from Hong-Kong, with a considerable herbarium collected 
there, containing several additional species, which will be duly recorded in the present 
florula. He has also brought over a valuable collection of Chinese seeds, which he 
has presented to the Royal Gardens at Kew, and a large and interesting set of rice- - 
paper drawings of plants.
