to orange. Anthers linear, versatile. Stigma 4-partitc. Capsules 

 cylindrical-clavate, somewhat woody, strongly 4-ribbed, hispid, 

 many-seeded. 



In sandy waste places, and in cultivated fields. A Patagonian 

 plant, which is now perfectly established in the cornfields near 

 St. Heliers, Jersey, and also more sparingly on the sands of St. 

 Aubin's Bay. The late Mr. T. Clark found it abundantly on the 

 sands at Burnham, Somerset, and Mr. Borrer, at Weston, in the 

 same county. I possess a specimen from Laira, Plymouth, Devon, 

 collected by Mr. Keys ; and Mr. T. Archer Briggs has sent me 

 examples collected there in 1802. 



This species bears some resemblance to CE. biennis, but is more 

 slender and rigid, with much narrower and distinctly denticulate 

 leaves and a more lax raceme. It may always be distinguished 

 by the capsule, which is enlarged towards the apex instead of 

 tapering. The stem is branched in luxuriant examples, as in the 

 preceding, but is more pubescent. The flowers are about the same 

 size, but much brighter and deeper yellow, and become more de- 

 cidedly orange when they fade. Seeds smaller, paler, and less 

 angular, and the colour of the whole plant brighter green than in 

 (E. biennis.

GENUS III.—L UDWIGIA. Linn. {Elliot). 



Calyx-tube 4-sided-prismatic, cylindrical or turbinate, adhering 

 to the 'ovary, and not prolonged above it; limb divided to the 

 base into 4 segments, commonly persistent. Petals 4, often minute 

 or absent, inserted in the throat of the calyx. Stamens 4, inserted 

 wit lithe petals. Ovary 4-celled, usually crowned with a 4-lobcd 

 disk surrounding the stylopod ; placenta in the axis ; ovules very 

 numerous ; style short ; stigma capitate, often with as many 

 furrows as there are cells in the ovary. Capsule short, or rarely 

 elongated, 4-celled, frequently opening by the separation or per- 

 foration of the stylopod, at length 1-valved. Seeds very numerous, 

 with a thin testa without hairs. 



Aquatic or marsh herbs, with alternate or opposite, entire or 

 serrate leaves, and solitary, axillary, sessile, or shortly-stalked yellow 

 or purple flowers, frequently arranged so as to form a terminal 

 raceme. 



The name of this genus was given to it by Linnaeus, in honour of Christian Gottlieb 

 Ludwig, once professor of medicine at Leipsic, and author of " Defiuitiones Pkntarum" 

 and other botanical works.
