96 CLASSES. 



and 2 short ; calyx with 4 sepals and corolla of 4 petals, each fastened 

 to the receptacle by a part, with the form of a cross ; hence the name ; 

 one pistil in the centre of the flower, as the cabbage, mustard, radish, 

 gilly-flower. 2 orders, depending on the length of the pod. 1st, sili- 

 culosa, producing short round pods, as pepper grass, shepherd's purse. 

 The plants here are nutritious and medicinal. 2d, Siliquosce, with 

 long narrow pods, as radish and mustard. The turnip, and wall-flower, 

 are of this order. 



15th class, signifying, with the 16th, the brotherhoods, the union of 

 the filaments in 1 or 2 sets. The 13 orders of this cl-ass depend on 

 the number of stamens ; 1st, Triandria, 3 stamens, with filaments 

 united in one set at the bottom of corolla, and anthers separate, as 

 blue-eyed grass, tiger-flower. 5th, Pentandria, as passion-flower, 

 stork-bill, geranium. 7th order, Heptandria, including the green-house 

 geraniums, of many beautiful varieties, and mostly natives of the cape 

 of Good Hope. 10th, Decandria, containing another genus of gera- 

 niums, with 10 stamens. 13th, Polyandria, many stamens ; the group 

 columnifera, stamens united in form of a column, as the hollyhock, 

 mallow, cotton, tall japan rose. 



1 6th class, 2 (broth erhoods) stamens united by their filaments in 2 sets ; 

 flowers papilionacious, or butterfly-shaped, (the flower, with 10 sepa- 

 rate stamens are in the 10th class.) The orders depend on the num- 

 ber of stamens. Order Pent-octandria, (5 and 8 stamens,) as the 

 corydalis, fnmaria, seneca-snake-root. 10th, Decandria, leguminous 

 plants, as the bean and pea tribe, rattlebox, clover, locust tribe, indigo, 

 sandal wood, liquorice, sensitive plant, gum arabic, tamarind, furze. 

 Some give 8 orders in this class. 



17th class, (a union of anthers,) mostly 5 stamens. Some are re- 

 tained in the 5th class, but are distinguished from that by the union of 

 anthers and compound flowers, which are distinguished as semi-floscu- 

 lous, (having ligulate florets, )flosculous, (having tubular florets,) and 

 as radiated with tubular florets in the centre and ligulate at the cir- 

 cumference. These florets are called rays. Plants of the 1st char- 

 acter have a bitter narcotic milky juice, as lettuce, dandelions ; the 

 2d are bitter in leaves and roots, as burdock ; and the 3d corymnif- 

 erous, as crysanthemum, aster, etc. Tansey and boneset are of this 

 division. The daisy, sunflower, etc., are of the order. This class, 

 depending on the situation of the florets, these are 1st, perfect, when 

 with stamens and pistils ; 2d, barren, with stamens only ; 3d, fertile, 

 with pistils only ; and 4th, neutral, without stamens or pistils. 



5 orders in this class, 1st, Equalis, compound florets, all perfect, 

 distinguished by florets ligulate, tubulous, (in a head, as dandelion,) 

 or tubulous without rays, as boneset, thoroughwort. 2d, Superflua, 

 the pistils of the ray being without stamens and therefore superfluous. 

 There are 2 sections of the order, 1st, without rays, as life everlasting,
