long as the calyx, villous, solitary in the axil of a laiiceolate-acuminate spread- 

 ing or reflexed bract, usually about as long or half as long again as itself. 

 Calyx campanulate, rather longer than the tube of the corolla, deeply 5-partite, 

 the sepals very unequal in size, the 2 lowermost very broadly ovato-elliptical, the 

 2 above these elliptic-lanceolate, the fifth and superior much narrower, lanceo- 

 late ; all acute or somewhat acuminate, about 5-uerved, spreading and enlarged 

 in fruit. Corolla very large, drooping, from 2 to 2^ inches long, and about an 

 inch wide across the mouth, the limb tubuloso-campanulale, compressed horizon- 

 tally, the upper side flattish, with a prominent ridge or keel (fold of the corolla) 

 along its centre not extending to the margin of the upper lip, ventricose or inflated 

 beneath, strongly contracted at base into the very short, white, firm and shining, 

 5-lobed tube, from which the limb is deflexed at an obtuse angle ; quite glabrous 

 externally, of a fine purplish pink and shining, paler and nebulously mottled 

 white and purple underneath, with several purple rather indistinct rib-like streaks 

 running longitudinally ; obliquely 2-lipped or rather 4-lobed, the upper lobe 

 extremely short, truncate and almost obsolete, slightly and obtusely emarginate 

 or nearly entire, ascending, the two lateral lobes as long as the upper one and 

 similar in shape, but smaller and quite entire ; lowermost lobe the longest, 

 spreading or reflexed, entire, rounded or occasionally slightly pointed, within 

 rugose, sparsely beset with long, white, erect, jointed hairs, and beautifully 

 speckled with ocellated spots, consisting of deep purple dots in white nebulous 

 rings, extending backwards to the top of the tube, where they coalesce for the 

 most part into a pale-coloured field, thickly dotted with brownish puiple, occupy- 

 ing the whole of the lower and inner side of the corolla. Stamens 4, without the 

 least rudiment of a fifth, ascending and converging in pairs close beneath the 

 style, and applied with it to the opposite side of the corolla to about half the length 

 of the limb : filaments white, broad, flat and glabrous, of the longer or outer sta- 

 mens much curved inwards at their origin, those of the shorter pair but slightly 

 bent ; anthers very large, bright yellow, slightly hairy, mostly with a few purple 

 dots, lobes ovoid-oblong, united only at base, somewhat pointed, bursting ante- 

 riorly. Ovary oblong-conical, very hairy, sessile, surrounded at base with a yel- 

 lowish, lobed, angular gland, obliquely tapering at top into the style. Style as 

 long as the outer stamens, cylindrical, somewhat arcuate, slightly hairy in its 

 lower half, glabrous and purplish above, horizontally cleft at apex into two equal, 

 subacute, appressed or diverging lobes, resembling the mouth of a serpent. Cap- 

 sules large, ovate, downy, tipped with the long withered style. Seeds very nume- 

 rous, dull reddish brown, small, oblong and truncate, with a lateral furrow, 

 covered with a network of deep angular cells like a honeycomb. 



In our species, and probably in all the rest of this genus, the capsule is imper- 

 fectly 4-valved ; of these valves, the lateral pair of sutures, which by their inflexed 

 margins form through their junction with the placenta the 2 cells, split widely 

 open, whilst of the 2 remaining sutures, whose edges do not project into dissepi- 

 ments, the upper dehisces in the centre above, the lower continuing closed as a 

 simple commissure. The same structure is seen in Collinsia bicolor, and pro- 

 bably in many other genera of this natural order. 



I found, June 14th, 1849, in a hedge betwixt Stokes bay and the Grange farm, 

 near Gosport, a specimen of D. purpurea having near the centre of each flower a 

 pair of small subacute spurs hollow within and pointing backwards, in shape, &c., 

 exactly as in Linaria.
