 dotted beneath ; stem very much branched ; root fusiform. 

 Tf.. F. Native of Spain, according to the herbarium of Jussieu. 

 Flowers yellowish. 



Rosemary-leaved Aplophyllum. PI. 1 foot. 



Cult. These plants will grow in any light rich soil, but in a 

 poor dry light soil they will endure our winter better. Cuttings 

 planted under a hand-glass will root readily, and many of them 

 may be increased by dividing the plants at the root, but by seeds 

 is the best and surest method ; these are sure to ripen in abund- 

 ance if the summer proves favourable. 



Genus allied to Rutece.

V. DICTA'MNUS (an ancient name of what is supposed to 

 be Origanum Dictumnus, Fraxinella because the leaves resemble 

 those of Frdxinus, the ash). Lin. gen. no. 522. D. C. prod.

 parted, unequal. Petals 5, unguiculate, unequal. Stamens 10, 

 declinate ; filaments awl-shaped, filiform, unequal, with glan- 

 dular tubercles at the apex ; anthers roundish. Style 1, decli- 

 nate, striated lengthwise, terminated by a papillose, blunt stigma. 

 Capsule stipitate, composed of 5 carpels, which are connected

 long; calyx unequal. Tf.. H. Native of the south of Europe, 

 particularly in Germany, France, Spain, Austria, and Italy. D.

 hot. 316. 1. 116. Lam. ill. t. 344. f. 1. Fraxinella, Clus. pann. 54. 

 It is called by Gerarde Bastard or False Dittany, and by Par- 

 kinson, False White Dittany. Seeds pear-shaped, black, shining. 

 The whole plant, especially when gently rubbed, emits an odour 

 like that of lemon-peel, but when bruised it has something of a 

 balsamic scent. 1 his fine scent is strongest in the pedicels of 

 the flowers, which are covered with glands of a rusty-red colour, 

 exuding a viscid juice or resin, which exhales in vapour, and in 

 a dark place may be seen to take fire. The root was formerly 

 used in medicine, and it is said with much success, as a drastic 

 opiate. This plant, for its beauty and fine scent, deserves a 

 place in every collection. The varieties are as follows : 



Var. a, purpiirea (D. C. prod. 1. p. 712.) petioles obscurely 

 edged ; petals pale-purple, striped with deeper veins. D. rubra, 

 D. Fraxinella, Link. enum. 1. p. 398. 



Var. ft, alba (D. C. prod. 1. p. 712.) petioles with rather 

 broader edges; petals white. D. albus, Link. enum. 1. p. 398. 



Fraxinella. Fl. May, June. Clt. 1596. PI. 1 to 1 J- foot.
