332 THE SCROPHULARIA FAMILY. — [Mimalus. 
ing singly on axillary peduncles. Calyx tubular, with 5 prominent angles; 
and 5 short teeth. Corolla with a broad tube, and 5 flat lobes arranged 
in two lips; the upper one 2-lobed and sometimes erect; the lower one 
spreading and 3- lobed, the central lobe often notched. Stamens 4, Cap- 
sule opening in 2 valves in the middle of the cells. 
An American genus, which, besides the species now naturalized in Europe, 
comprises the Musk Mimulus and some others occasionally cultivated in 
our gardens. 
1. M. luteus, Willd. (fig. 744). Yellow Mimulus.—A perennial, with 
a shortly creeping rootstock, and erect or ascending stems, either glabrous 
or slightly downy, seldom above a foot high. Leaves ovate, coarsely 
toothed, glabrous. Peduncles 2 inches long or more, bearing a showy 
yellow flower, above an inch long, usually marked inside with several small 
purple spots at the mouth of the tube, and sometimes with a large purple- 
red or pink spot upon each lobe. 
On the banks of streams, and in moist, shady places, in north-western 
America and Chili; long cultivated in our flower-gardens, and now natu- 
ralized in boggy places i in many parts of Britain. £7. all summer. 
VI. LIMOSELLA. LIMOSEL. 
Small, tufted or floating annuals; the leaves and minute flowers mostly 
radical, Calyx 5-toothed or lobed. Corolla regular, campanulate, 5-lobed. 
Stamens 4. Anthers1-celled. Capsule globular, with a very thin pericarp, 
scarcely dehiscent. 
Besides our European species the genus comprises but very few from 
southern Africa and Asia. 
1. G. aquatica, Linn. (fig. 745). Common Limosel.—A glabrous 
annual, forming little tufts of 1 or 2 inches diameter. Leaves on long 
stalks, oblong and entire, all radical as well as the minute flowers ; or occa- 
sionally a few slender stems are developed among the leaves, about an inch 
long, and bearing at their summit a similar tuft of leaves and flowers. 
Corolla of a pale rose-colour, scarcely longer than the calyx. 
In wet mud, or in places where water has stood, throughout Europe and 
a great part of Asia, Africa, and North America. Thinly scattered in 
England, and very local in Scotland, absent from Ireland, but from its 
small size it may be frequently overlooked. Fl. summer. 
VII. SIBTHORPIA. SIBTHORPIA. 
Slender, hairy, trailing herbs, with alternate leaves, and small, axillary, 
yellow or pinkish flowers. Calyx of 4 or more divisions. ~Corolla nearly 
rotate, with 5 lobes, or one more than the calyx. Stamens of the same 
number as, or one less than, the lobes of the corolla. Anthers 2-celled. 
Capsule compressed, divided into 2 cells, and opening in the middle of the 
cells in 2 valves. 
Besides the British species there is one from the Canary Islands, with 
larger yellow flowers, often cultivated in our gardens under the name of 
Disandra prostrata, and two from the Andes of South America.
