A perennial, vnth a sliortly 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 Cliili ; long cultivated in our flower-gardens, and now natu- 

 ralized in boggy places in many parts of Britain. Fl. all summer. 



YI. ZiiraOSEXi. LIMOSELLA. 



Small, tufted or floating annuals ; the leaves and minute flowers mostly 

 radical. Calyx 5-toothed or -lobed. Corolla regular, campanulate, 5-lobed. 

 Stamens 4. Anthers 1-celled. Capsule globular, with a very thin pericarp, 

 scarcely dehiscent.

 southern Africa and Asia. 



1. Common Iiimosel. Iiimosella aquatica, Linn. 

 (Eng. Bot. t. 357.) 



A glabrous annual, forming little tufts of 1 or 2 inches diameter. Leaves 

 on long stalks, oblong and entire, all radical as weU as the minute flowers ; 

 or occasionally 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, thi-oughout Europe and 

 a great part of Asia, Africa, and North America. Thinly scattered in 

 Britain, and very local in Scotland, but from its small size it may be 

 fi-equently overlooked. FL summer.

 yellow or pinkish flowers. Calyx of 4 or more divisions. CoroUa nearly

 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.
