36 DK. MEISNEB ON CHA.M^!LAUCIE^. 



gardens were two or three species of Calycothrix, to which have 

 been quite recently added two fine species of Genetyllis, published 

 with beautiful figures in the ' Botanical Magazine ' for July, plates 

 4858 and 4860. On comparing these plates with the specimens 

 in Mr. Drummond's last (6th) collection, I have been led to 

 examine also the whole of the Ghamcelauciece it contains, and have 

 found almost all of them to be new species, the characters of which 

 form the subject of this paper. It will show at the same time that 

 in the beautiful genus Verticordia certain details of structure 

 appear to have remained unnoticed till now, while others have been 

 explained in a wrong or at least unsatisfactory manner, and that 

 both these circumstances will render necessary certain alterations 

 in the character and subdivision of the genus. To conclude these 

 introductory lines with a survey of the progress our acquaintance 

 with Ghamcelauciece has made during the last twenty-seven years, 

 we find that in 1828 (DeC. Prodr. vol. iii.) there were only ten 

 species known, distributed in five genera. To these were added 

 by Dr. Schauer, in his ' Monograph ' (1841) and in the ' Plantae 

 Preissianse' (1844) six new genera, including sixty-two species, 

 mostly discovered by Baron von Hiigel, Drummond and Preiss, 

 and partly previously published by Endlicher and Prof. Lindley. 

 Another addition of twenty-six new species from Drummond's 

 collections was published in 1849 by Turczaninow in the 'Bulletin 

 de la Soc. Imp. d'Hist. Nat. de Moscou,' tomes xx. and xxii. 

 (1847-49), and of one Genetyllis by Lindley in Mitchell's Exped. 

 ii. p. 178 (which Dr. Muller refers to his Lhotskya genetylloides in 

 the Transact. Philos. Soc. of Yictoria, no. 1. p. 16), so that, with 

 the following twenty-two new species, the total number of Cha- 

 mcelauciece described up to this day amounts to 121 species, com- 

 prised in eleven genera.
