ORDER ANGIOSPERM1A. 131 



wastes and by road sides ; in flower from June to 

 November. The stem is simple and terminated by a 

 dense spike of rather large flowers, sometimes called 

 Butter and Eggs, from the fine contrast of yellow and 

 orange which they present. The leaves are linear 

 and crowded. Of the Peloria, one of its extraordi- 

 nary varieties, we have already spoken. 



The curious Collinsia, of the shady banks of the 

 Ohio, and the western forests of Pennsylvania, belongs 

 also to the same natural order with the preceding ge- 

 nus. It has a 5-cleft calyx ; a bilabiate corolla, with 

 the orifice closed ; the upper lip bifid, the lower trifid, 

 the intermediate segment forming a keeled sack, in 

 which are included the declinate style and stamens. 

 The capsule is globose, partly 1 -celled, and imperfect- 

 ly 4-valved ; seeds few, umbilicate. The C. verna 

 is a low annual, flowering in May ; with opposite, ovate, 

 oblong, sessile, obtuse leaves, the lower ones petiolat- 

 ed ; and having a capsule containing only 2 or 3 seeds. 

 The flower is beautifully particolored, the upper lip 

 being white, the lower a fine blue. A second, and very 

 similar annual species is found on the banks of the Ar- 

 kansa, west of the Mississippi; which I propose to call 

 Collinsia *violacea from the peculiar hue of the corolla. 

 In this species the capsule contains 8 to 12 seeds. 



Another very ornamental American genus of this 

 order is Gerardia, of which there are no inconsidera- 

 ble number of species in the United States, and sev- 

 eral of them rather common. The genus is divisi- 

 ble into 2 sections from the color of the corolla ; as, 

 those with purple, and those with yellow flowers. In 

 the form of the corolla and general aspect they appear 

 as the counterpart of the European Foxglove, and 

 might well be called the American Foxglove. They 

 have acalyx which is hail" way down 5-cleft, or 5-tcoth- 

 ed. The corolla is somewhat campanulate, unequally
