rindon, Oliver, Baxter of Oxford, Lindley ('Ladies'
Botany'), and Figuer, without being able to find the meaning of
'Lentibulariaceae,' 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.

Whatever the name may mean--it is bad Latin. There is such a word as
Lenticularis--there is no Lentibularis; and it must positively trouble us
no longer.[14]

The Butterworts are a perfectly distinct group--whether small or large,
always recognizable at a glance. Their proper Latin name will be
Pinguicula, (plural Pinguiculae,)--their English, Bog-Violet, or, more
familiarly, Butterwort; and their French, as at present, _Grassette_.

The families to be remembered will be only five, namely,

1. Pinguicula Major, the largest of the group. As bog plants, Ireland may
rightly claim the noblest of them, which certainly grow there luxuriantly,
and not (I believe) with us. Their colour is, however, more broken and less
characteristic than that of the following species.

2. Pinguicula Violacea: Violet-coloured Butterwort, (instead of
'vulgaris,') the common English and Swiss kind above noticed.

3. Pinguicula Alpina: Alpine Butterwort, white and much smaller than either
of the first two families; the spur especially small, according to D. 453.
Much rarer, as well as smaller, than the other varieties in Southern
Europe. "In Britain, known only upon the moors of Rosehaugh, Ross-shire,
where the progress of cultivation seems likely soon to efface it."
(Grindon.)

4. Pinguicula Pallida: Pale Butterwort. From Sowerby's drawing, (135, vol.
iii,) it would appear to be the most delicate and lovely of all the group.
The leaves, "like those of other species, but rather more delicate and
pellucid, reticulated with red veins, and much involute in the margin. Tube
of the corolla, yellow, streaked with red, (the streaks like those of a
pansy); the petals, pale violet. It much resembles Villosa, (our Minima,
No. 5,) in many particulars, the stem being hairy, and in the lower part
the hairs tipped with a viscid fluid, like a sundew. But the Villosa has a
slender sharp spur; and in this the spur i
