180 CHEIRAN'THUS CHEI'RI EXAMINED. 



there are two divisions of the genera ; one having- 

 the calyx open, with the leafits spreading; the 

 other, to which this plant belongs, having a close 

 cup, and the leafits approaching each other at the 

 top. This genus is named Cheiran'thus, and is 

 distinguished from the others, of the same division, 

 principally by two little roundish bodies, called 

 glands, which surround the bottom of the two 

 shorter stamens [PLATE 1.]; but they are not 

 easily seen without the assistance of a magnifying 

 glass. These glands, as I have already told you, 

 form the nectaries of the Wall-flower. " The cup 

 " consists of four upright spear-shaped leafits, of 

 " which the two outermost bulge, or swell a little 

 * 6 at the bottom. There are four petals, forming 

 " a cross, the claws as long as the cup. The 

 " four long stamens are of the same length as the 

 " calyx ; and the two shorter ones are curved out- 

 *' wards at the lower part," being pushed out, as it 

 were, and made to appear shorter, by the glands 

 that surround them at the bottom. " The anthers 

 " are long, upright, pointed at the top, and cloven 

 " at the bottom. The germen is as long as the 

 " filaments, and supports a very short style, with 

 " a divided summit. The seed-vessel is a long 

 " pod, containing several flat egg-shaped seeds." 



The specific name of our plant is Chei'ri. It is 

 supposed by several botanists to be a variety of the 

 native species, Fruticulo'sus, and is so common in
