294 THE PRIMROSE FAMILY. (Cento 
Asia, northern and even tropical America, and Australia, but every- 
where thinly scattered, or frequently overlooked. Local, but in- 
dicated in many localities in England, and Scotland; rare in Ireland. 
Fl, summer. 
IX, SAMOLUS. SAMOLE. 
Herbs, with alternate leaves and flowers, in terminal racemes. Calyx 
campanulate, partially adhering to the base of the ovary, with 5 teeth 
or lobes. Corolla with a short tube, 5 spreading lobes, and a small © 
scale between each lobe, alternating with the stamens. Capsule in- 
ferior, opening in 5 valves. 
A small genus, belonging, with the exception of our own species, ex- 
clusively to the southern hemisphere. 
1. S. Valerandi, Linn. (fig. 663). Brookweed. A glabrous, bright 
green annual or perennial, with a tuft of obovate and spreading 
radical leaves. Flowering stems 3 or 4 inches to near a foot high, 
slightly branched, bearing a few obovate or oblong leaves, and loose 
racemes of small white flowers. Pedicels rather long, with a green 
bract a little above the middle. Capsules small, globular, crowned by 
the short broad teeth of the calyx. 
Generally diffused over all parts of the world, most abundant i in mari- 
time sands and marshes, but in many countries found also far inland. 
In Britain, almost always near the sea, and chiefly along the west coast. 
Fl, summer and autumn. 
XLVII. LENTIBULACEA. THE PINGUICULA FAMILY. 
‘Marsh or aquatic plants, with radical or floating leaves (or 
sometimes none), and very irregular flowers, either solitary or 
several in a raceme, on leafless, radical, or terminal peduncles. 
Calyx variously divided. Corolla 2-lipped, projecting at the 
base into a pouch or spur. Stamens 2. Ovary and capsule 
l1-celled, with several seeds attached to a central placenta. 
A family of very few genera, dispersed over the greater part of the 
globe. Their spurred flowers have a general resemblance to those of 
Linaria in Scrophulariacee, next to which they might perhaps be better 
placed, although the ovary and capsule are those of Primulacec, with 
which botanists more generally associate them. 
Calyx 4- or 5-lobed. Leaves entire, radical . . - i . 1. PINGUICULA. 
Calyx 2-lobed. Leaves floating, much divided ; ; 2 . 2. UTRICULAR EAD 
I. PINGUICULA. BUTTERWORT. 
Plants growing in bogs or on wet rocks, with radical, entire leaves, 
~ and yellow or purple flowers, on leafless radical peduncles. Calyx with 
4 or 5 teeth or lobes, arranged in 2 lips. Corolla spurred, with a broad, 
open mouth; the upper lip short, broad, and 2-lobed ; the lower one 
usually longer, broadly 3-lobed. Capsule opening in 2 or 4 valves. 
The genus is limited to the northern prepuce = with the ee i 
of one Fuegian Species. r
