There are three varieties given in Sowerby: 1. Vulgaris, 2. Greater-flowered, and 3. Lusitanica, white, for the most part, pink, or 'carnea,' sometimes: but the proper colour of the family is violet, and the perfect form of the plant is the 'vulgar' one. The larger-flowered variety is feebler in colour, and ruder in form: the white Spanish one, however, is very lovely, as far as I can judge from Sowerby's (old Sowerby's) pretty drawing.
The 'frequent' one (I shall usually thus translate 'vulgaris'), is not by any means so 'frequent' as the Queen violet, being a true wild-country, and mostly Alpine, plant; and there is also a real 'Pinguicula Alpina,'
which we have not in England, who might be the Regina, if the group were large enough to be reigned over: but it is better not to affect Royalty among these confused, intermediate, or dependent families.
2. In all the varieties of Pinguicula, each blossom has one stalk only, growing from the ground and you may pull all the leaves away from the base of it, and keep the flower only, with its bunch of short fibrous roots, half an inch long; looking as if bitten at the ends. Two flowers, characteristically,—three and four very often,—spring from the same root, in places where it grows luxuriantly; and luxuriant growth means that clusters of some twenty or thirty stars may be seen on the surface of a square yard of boggy ground, quite to its mind; but its real glory is in harder life, in the crannies of well-wetted rock.
3. What I have called 'stars' are irregular clusters of approximately, or tentatively, five aloeine ground leaves, of very pale green,—they may be six or seven, or more, but always run into a rudely pentagonal arrangement, essentially first trine, with two succeeding above. Taken as a whole the plant is really a main link between violets and Droseras; but the flower has much more violet than Drosera in the make of it,—spurred, and five-petaled,[[11]] and held down by the top of its bending stalk
as a violet is; only its upper two petals are not reverted—the calyx, of a dark soppy green, holding them down, with its three front sepals set exactly like a strong trident, its two backward sepals clasping the spur. There
are often six sepals, four to the front, but the normal number is five. Tearing away the calyx, I find the flower to have been held by it as a lion might hold his prey by the loins if he missed its throat; the blue petals being really campanulate, and the flower best described as a dark bluebell, seized and crushed almost flat by its own calyx in a rage. Pulling away now also the upper petals, I find that what are in the violet the lateral and well-ordered fringes, are here thrown mainly on the lower (largest) petal near its origin, and opposite the point of the seizure by the calyx, spreading from this centre over the surface of the lower petals, partly like an irregular shower of fine Venetian glass broken, partly like the wild-flung Medusa like embroidery of the white Lucia.[[12]]
4. The calyx is of a dark soppy green, I said; like that of sugary preserved citron; the root leaves are of green just as soppy, but pale and yellowish, as if they were half decayed; the edges curled up and, as it were, water-shrivelled, as one's fingers shrivel if kept too long in water. And the whole plant looks as if it had been a violet unjustly banished to a bog, and obliged to live there—not for its own sins, but for some Emperor Pansy's, far away in the garden,—in a partly boggish,
partly hoggish manner, drenched and desolate; and with something of demoniac temper got into its calyx, so that it quarrels with, and bites the corolla;—something of gluttonous and greasy habit got into its leaves; a discomfortable sensuality, even in its desolation. Perhaps a penguin-ish life would be truer of it than a piggish, the nest of it being indeed on the rock, or morassy rock-investiture, like a sea-bird's on her rock ledge.
5. I have hunted through seven treatises on Botany, namely, Loudon's Encyclopædia, Balfour, Grindon, Oliver, Baxter of Oxford, Lindley ('Ladies' Botany'), and Figuer, without being able to find the meaning of 'Lentibulariaceæ,' to which tribe the Pinguicula is said by them all (except Figuier) to belong. It may perhaps be in Sowerby:[[13]] but these above-named treatises are precisely of the kind with which the ordinary scholar must be content: and in all of them he has to learn this long, worse than useless, word, under which he is betrayed into classing together two orders naturally quite distinct, the Butterworts and the Bladderworts.
