Orver II. DILLENIA'CEZ. (plants agreeing with Dille- 
nia in many important characters.) D.C. ann. mus. 17. p. 400. 
syst. 1. p. 395. prod. 1. p. 67. 
Parts of flower imbricate in the bud. Calyx of 4 or 5 perma- 
nent sepals (f. 15. a. f. 16. a.) but in Empedoclea numerous. Petals 
4-5, permanent (f.19.a.)or deciduous (f. 16. a.) alternating with the 
sepals. Stamens indefinite, free, (f. 17. a. f. 19. b.) or polydelphous. 
Anthers adnate, bursting inwards or laterally (f. 17. c.). Carpels 
1-celled, numerous, usually from 2 (f. 16. d.) to 5 (f. 15. a.) but 
sometimes solitary from abortion, capsular, baccate (f. 19. ¢.), 
or 2-valved (f. 15. e.), free (f. 15.a.), or connected into one fruit 
(f.19.c.). Seeds attached to the inner angle of the cells of the 
carpels, usually in 2 rows, numerous or few, sometimes solitary 
from abortion (f. 15. e. f.16.e.). Embryo small, placed in the 
base of a cartilaginous albumen. Elegant evergreen trees, shrubs, 
or climbing shrubs, with alternate simple, feather-nerved, entire 
(£. 17.), or toothed (f. 19.) leaves. Flowers solitary (f. 16, 18, 
19.), racemose (f. 17.) or panicled (f. 15.), terminal or lateral, 
usually yellow, emulating those of Cistus. This order differs 
from Ranunculdcee in the sepals being permanent, as well as in 
the anthers never bursting outwards, and from Magnoliacee@ and 
Anonacee in the parts of the flowers being disposed in a qui- 
nary order, not often ternary as in these orders. 
The medical properties of this order are hardly known; a 
decoction of their leaves or bark is astringent, but it is neither 
bitter nor aromatic, and is used for gargles, and the acid juice of 
the fruit of some species of Dillénia is used in India, mixed with 
water, as a pleasant beverage in fevers. The foliage of many 
of the species being extremely scabrous, are used, when dried, 
for the same purposes as fish-skin and sand-paper in Europe ; 
those of Trachytélla aspera are even employed in China for 
polishing works of metals. 
The seeds of the plants belonging to this order, retain their 
vegetative power but for a very short time, therefore the sooner 
they are sown after their arrival the more likely they will be to 
vegetate. Many of them will not retain their power of vege- 
tating more than 6 weeks or 2 months after they have been col- 
lected from the plant.
