genus, under the name of Decalo^lmimx but that was probably 

 from ignorance of the true Cliamcelaucia ; for he at the same time 

 published the original (7. ciliatum^ Desf , as a new Genetyllis. 



Caltthkix, Lab ill., and Lhotzkya, Schau., with the habit of 

 Chama^laucieae, and therefore included in them by all botanists, 

 have nevertheless some peculiarities of structure which distinguish 

 them much more from the above-mentioned genera than from 

 some Leptospermese. The stamens, ahvays indefinite and in several 

 rows (or very irregularly 1-seriate), even when reduced to below 

 10, are unknown in Euchama>laucie£e, and only found in Homa- 

 localyx among Thryptomenese ; the peculiar placentation and em- 

 bryo have already been alluded to. All these characters, if not 

 strictly intermediate between those of Chamseiauciese and Lep- 

 tospermese, show a rather more general affinity to tlie latter 

 than to the former ; yet the technical character derived from the 

 unilocular ovary, and the general aspect given by foliage and 

 inflorescence, oblige us to retain them in the tribe of Chama*- 

 lauciese. 



Calythrix is the principal genus amongst Myrtacese in which 

 minute, almost hair-like bodies, at the base of the leaves of a few 

 species, have been described as stipules. If they are really to be 

 considered such, which may be as yet somewhat doubtful, they 

 are quite rudimentary, and so uncertain in the few species where 

 they have been observed as to be useless for systematic descrip- 

 tion, whilst at the same time they appear to perform no function 

 in the economy of the plant. 



The name Calythrix has been objected to by some German 

 purists, and altered to Calycotlirix^ as being derived from kcO^^-^ 

 and Qpil\ but the elision of the hard terminal consonant of calyx 

 In composition, if not classical, has received the sanction of bota- 

 nists in other cases, as in Calydermos, Calystegiay &c., besides 

 having been fixed in the present case by the right of priority. 

 At any rate, if strict rules of etymology were followed, the altera- 

 tion would be to Trichoealyx (a name already preoccupied), not to 

 CalycotJirix ; for the meaning intended to be conveyed was liair- 

 like calyx, not calyx-like liairs, 



AVith regard to the separation of Lhotzlya from Calytlrix, as 

 proposed by Schauer, there has appeared to me no inconvenience 

 in maintaining it, although in opposition to the more recent vle^^9 

 of F. Mueller. The constant want of any point or awn to the 

 calyx-lobes, in all the eight species known, give it a very distme 

 aspect ; and there can be no difficulty about the supposed inter-
