 and all succeeding voyagers. 



The accompanying plate and analysis of this curious little plant represent ah its characters, and especially 

 those which have induced me to retain the genus which the illustrious Jussieu formed, but which has not been 

 adopted by any succeeding author. It is to be distinguished from Sisyrinchium by its very remarkable habit, 

 coriaceous perianth, and, more especially, by the capsule dehiscing at the apex, and the ovules and seeds occupying 

 only the lower hah of each placentiferous dissepiment. To the southward of the Strait of Magalhaens, where 

 SisyrincMa do not extend, this little plant represents that genus, and is also the analogue of the Libert'ue of New 

 Zealand. 



The curious and beautiful distichous arrangement of the foliage, is characteristic of this and of some other 

 especially alpine Antarctic plants, belonging to several natural orders, amongst the majority of the species of which 

 such a foliation is foreign or very rare. Thus, in Cyperacea it is seen in Oreobolus pectinatm (pt. 1. t. 49); amongst 

 Rest iacea, in Gaimardia pallida (p. 86); amongst Alwnacea, in Tetroncium Hagellanicum (t. 128); and amongst 

 Juncea, in the Peruvian Distichya muscoides, Nees and Meyen (Nov. Act. Acad. Caes. vol. xix. Suppl. p. 77), which is 

 probably the Goudotia Tolimensis, Decaisne (Arm. Sc. Nat. ser. 3. vol. iv. p. 83. t. 4). This tendency to assume a 

 certain habit, which these otherwise wholly dissimilar plants present, is perfectly analogous to what occurs even more 

 conspicuously in the vegetation of the Cape of Good Hope and Australia ; and one of the most singular phenomena 

 of the vegetable kingdom.

Hab. Strait of Magalhaens and throughout Fuegia, Commerson, Banks and Solander, 8fc, Falkland 

 Islands, most abundant, Gaudichaud,, and all succeeding voyagers. 



A very elegant little plant, remarkable, especially in the Falkland Islands, for its very sweet-scented flowers. 



The extrorse anthers of this genus have been hitherto overlooked, from the versatde nature of then attachment. 

 The embryo, described as amphitropal, at first is nearly atropal ; but apparently during the maturation of the 

 ovarium the seed becomes partially inverted, so as to be placed at right angles with the funiculus, and the embryo 

 is consequently heterotropal. 



Callixene is an Antarctic-American, and New Zealand genus. From the latter country Mi'. Colenso has sent 

 the C.parvifiora, Hook. fil. (Hook. Ic. Plant, t. 632), which grows at the foot of large Beech trees, lying prostrate
