stion puts it out of the power of naturalists in general to have recourse 
to them. The necessity for their publication may be considered as still 
less, now that engravings of this species have appeared in the Botanical 
Magazine and Botanical Register. These were given to the world 
since my drawings had been executed ; but these last seem to me to con- 
tain more important analyses of the parts of fructification than either of 
the excellent works now mentioned. 
The irritability of the column of fructification, which is perhaps more 
evident in this individual of the genus than in any other, is a well known 
circumstance. It is bent, as Mr Brown describes it, " duplid flexura 
or, in the words of Sir James Smith, it is " curved, and recurved 
and if this column be touched ever so slightly, or if any part of it be 
pressed with the finger, it immediately starts over to the other side of 
the flower, and is supposed, by this process, to scatter the pollen from 
the anthers to the stigma. 
The genus StyUdium was first established by Swaiitz; but Sir 
James Smith had the honour of proposing the name, and at the same 
time communicating specimens to the Swedish Professor and to Labil- 
LAKDiERE. It is uow Universally adopted, although the latter author, 
in a memoir in the Annates du Museum (THistoire Naturelle, called the 
genus Decandollea ; and Smith himself, in Exotic Botany, published 
two species, with excellent figures, under the name of Ventenatia. 
As an order, StylidecB is placed by Mr Brown near Campanulaceoe, 
on the one hand, and Goodenovios on the other, differing from the for- 
mer in its " reduced number of stamens, and the remarkable and inti- 
mate adhesion of their filaments with the style, through the whole length 
of both organs and from the latter, (as also from Campanulacea), " in 
the imbricate aestivation of the corolla, and, where its segments are un- 
equal, in the nature of the irregularity."" 
It is curious that Richard, and following him Jussieu, should have 
considered the labellum of Brown as the stigma ; and as such have 
figured and described it in the 18th volume of the Annates du Mu- 
seum, both in StyUdium laricifolium and S. Armeria of Labillar- 
DiERE. This idea is satisfactorily controverted by our learned country- 
man, in his General Remarks in the Appendix to Captain Flinders' 
Voyage, which is transcribed by Mr Gawler in the Botanical Register. 
Among a no less number than 45 species of StyUdium described in 
the Prodr. Fl. Nov. Holl. only two approach to the nature of shrubs, 
one of which is our S. laricifolium (S. tenuifolium. Brown). It is, 
like nearly all the others, an inhabitant of the neighbourhood of Port 
Jackson, and is readily cultivated in a mixture of loam and peat-earth, 
increasing by cuttings, and proving a great ornament to the greenhouse, 
as it flowers in the early part of spring.
