spicate infloresceBce, and especially in the ovules, pendulous as 

 in Leptospernnim^ not ascending as in Callisternon. This cha- 

 racter in the typical section Eukunzea^ where the ovules are not 

 very numerous, is very definite; but in a second section, for which 

 I have extended Lindley's name of Salisia, the ovules are so 

 densely crowded as to be thrown into a horizontal position, or 

 the upper ones slightly ascending and the lower ones alone really 

 pendulous, thus passing into the arrangement of ovules obser- 

 vable in some specimens of Callistemouj where they are equally 

 crowded. J^imzea £axte?'Zj^chau.j approaches Callistemon also in 

 the colour of the stamens, and to a certain degree in inflo- 

 rescence, and has, indeed, been published as a Callistemon^ first by 

 Lindley, and afterwards by F. Mueller, and as a distinct genus 

 {Pentagonaster) by Klotzseh ; but, from the 5-celled capsule, 

 crowned by the large persistent calyx-lobes, together with the 

 habit and foliage, it would appear to have been better placed by 

 Schauer in Kunzea, K, sericea^Tnrcz.y is another somewhat ano- 

 malous species : the flowers are large, and more unisexual than in 

 other species : the male inflorescences form clusters rather than 

 heads; and, prompted by its apparent beauty, as compared with 

 Lejptospermumy it was proposed as a genus, under the name of 

 Salisia, by Lindley, There appears, however, to be no essential 

 character to separate it from Ktmzea. The female flowers are 

 solitary and sessile ; and it is a fruiting specimen, retaining only 

 three solitary capsules, that Labillardiere figured as Lepfospermum 

 sericeum, whilst he appears to have described the flowers from a 

 specimen of Lepfospermum lanigerum. 



Callistemon, Br., also included by the older authors in Me- 

 trosideros upon purely artificial grounds, was early removed by 

 Brown aa being more nearly allied to Melaleuca^ with whicb 

 r. Mueller now proposes to unite it. It appears, however, to be 

 more convenient to retain it as a small natural group, connectmg 

 Ktmzea (and, through Kunzea, Leptospermum) with Melaleuca. 

 "We have already seen how it passes into the former through 

 Knnzea Baxteri ; and on the other hand, whilst it is generally dis- 

 tinguished from 31elaleuca by the free stamens, there are some 

 forms of Callistemon lanceolains^ and especially of C speciosuh 

 where they ai-e more or less distinctly united in clusters at the 

 base, whilst in a few Melaleucas the union in clusters is so short 

 as to be scarcely perceptible. The species of Callistemony t?sti- 

 mated by some botanists at about eighteen, but reduced in the 

 ' Flora Australiensis ' to ten, are scarcely to be distinguished frt*^
