Plant and Fungal Species Descriptions

From a critical survey of the tribe Leptospermese of the family Myrtacese in Beutham's Flora Australiensis, it will be seen that there are two special characteristics which distin^iisli the genera.In the five genera -ScJioltzia, Bceclcea, Astartea, Hypocalymna and Balaustion -the leaves are opposite.The genera Agonis, Leptospermum and Kunzea are distinguished from the five genera mentioned above by having alternate leaves.It is in regard to the last three genera with free stamens that I propose to offer some remarks.In Bentham's key to the genera, the main distinctions are as follows :Flowers sessile in globular heads.Stamens free, definite, or if indefinite none opposite the centre of the petals : Agonis.Flowers solitary or crowded, but not in heads : Leptospermum.Flowers closely sessile.Stamens exceeding the petals : Kunzea.Exceptions are made in some species of Kunzea for the flowers being " closely sessile ".
