Cult. The plants of this order are not worth cultivating but 

 in the gardens of the curious, as neither their leaves nor flowers 

 possess any beauty. They will grow in a mixture of loam and 

 peat, and young cuttings will probably strike root in a pot of 

 sand, tinder a hand-glass, in heat. 



ORDER LXXII. AQUILARI'NEjE (plants agreeing with 

 Aqidlaria in important characters). R. Brown, congo. p. 25. 

 D.C. prod. 2. p. 59. 



Calyx or perigone, turbinate, coriaceous, 5-lobed (f. 12. e.) ; 

 segments ovate, acute, spreading, permanent (f. 12. /.). Urceo- 

 lus adhering to the bottom of the perigone, 5-parted, with bifid 

 lobes (f. 12. b. d.). Stamens 10 (f. 12. 6.), with short filaments 

 protruding between the lobes of the urceolus, bearing long ver- 

 satile anthers (f. 12. e.~). Ovary free (f. 12. c.), stipitate ovate, 

 crowned by a short simple stigma. Capsule pear-shaped (f. 12. 

 g.), 2-valved, 2-celled (f. 12. _/.), with a dissepiment in the 

 middle of each valve (f. 12._/.). Seeds solitary in the cells from 

 abortion, arillate or tailed. Trees, with alternate, feather- 

 nerved, quite entire leaves. This order is not sufficiently known. 

 It differs from Saimjdece in the seeds being fixed to a dissepi- 

 ment, not to the parietes ; from Chailletiacece in the seeds being 

 erect, not inverted, as well as in the stamens being twice the 

 number of the lobes of the perigone ; from Thymelece in the 

 fruit being 2-valved, 2-celled, 2-seeded. The genera are badly 

 defined, and the species are scarcely known.
