on the outside with deeply coloured veins, about half an 
inch long. Calyr smooth; smaller leaflets three, ovately 
oblong, obtuse, faintly aud partially coloured, concave, the 
uppermost one standing apart and inclining along the vex- 
illum, the lower two subtending the carina; larger ones 
lateral, as long as the carina, flat, inequilaterally cordate, 
obtuse with a small point, more deeply coloured at the 
inner surface. Verillum dipetaleus, short, nearly colour- 
less; petals unequally bifid, inner lobe broad slanted in- 
wards reflexed, outer short narrow subulate upright; latent 
ale (see following article, PoIVGALA ligularis) 2, alternate 
with the 4 lower leaflets of the calyx, small, colourless, sub- 
ulately linear, inserted at the base ofethe stamineous tube, 
upright, close-pressed and sometimes entirely grown to the 
tube: carina green below, deep rose-coloured above, with 
a white decompounded multifid crest or pencil. Stamens 
and pistil nearly as in PoLVdaIA ligularis of the following 
article (637). 
We shall now add the very instructive observations of 
Mr. Brown on the natural order to which the subject of this 
article belongs. 
* Pozycaeæ. The curious observation of Richard, that 
“ the arillus of the seed, whether general or partial, is never 
** found in the Dicotyledonous orders with monopetalous 
** flowers, seems to have determined Jussieu (in Annales du 
* mus. 14. 386. et segg.) and other French botanists to re- 
* move PoLvcaLa, remarkable for its caruncula umbilicalis, 
“ from Rhinanthacee with which they had placed it, and 
“ to consider it, along with some nearly related genera, as 
* forming a distinct polypetalous order. They appear to 
* me, however, not to have taken so correct a view of the 
“ structure of its Corolla as Adanson (Fam. des plantes 2. 
* 348.), who very justly observes, that both in this genus 
„and Securipaca, which he rightly associates with it, the 
* apparently monopetalous corolla is made up of three pe- 
“ tals, united by the means of the cohering filaments, the 
* external sutures remaining visible; but Adanson himself 
has not observed the minute rudiments of two additional 
“ petals in Securıpaca, the existence and position of which 
“ assist in explaining the nature of the irregularity in Pory- 
' * GALA, where no such rudiments are found, but in which 
* the corolla is in every other respect very similar. À much 
“ nearer approach to regularity, however, takes place in an
