CRYPTOCARYA

Lepidium, &c. All C. are harmless, and most are rich in sulphur 
compounds (to which the smell of boiling cabbages is due), and are 
thus useful in scurvy &c. 
Classification and chief genera (after Prantl) : 
The grouping of the smaller divisions of the order and the defining 
of the genera is a most difficult task. Many classifications have been 
devised. Prantl (in Nat. Pfl. ) bases his largely upon the hairs borne 
on the leaves. Others rely on characters of fruit and embryo &c. In 
any case the identification of a cruciferous genus is a difficult matter; 
we shall not here go into the details of the classification, but merely 
give Prantl’s groups and the chief genera belonging to them. 
A. Hairs simple or none : no glandular hairs. 
I. Thelypodieae (stigma equally developed all round; style un- 
divided or prolonged above middle of cpls., or turned back). 
1. Stanleyinae: Pringlea, Thelypodium. 
2. Cremolobinae : Cremolobus. 
3. Heliophilinae : Heliophila. 
4. Chamirinae : Chamira. 
II. Sinapeae (stigma better developed over placentae). 
5. Lepidiinae: Subularia, Lepidium. 
6. Cochleariinae: Iberis, Cochlearia. 
7. Alliariinae: Alliaria. 
8. Sisymbriinae: Sisymbrium, Cakile, Isatis. 
9. Vellinae: Vella. 
10. Brassicinae: Sinapis, Brassica, Crambe. 
11. Cardamininae: Nasturtium, Cardamine. 
B. Hairs branched (a few exceptions): sometimes also glandular 
hairs. 
III. Schizopetaleae (stigma equal all round). 
12. Schizopetalinae : Schizopetalum. 
13. Physariinae: Physaria. 
IV. Hesperideae (stigma better developed over placentae). 
14. Capsellinae; Capsella, Draba. 
15. Turritinae : Arabis. 
16. Erysiminae: Erysimum, Cheiranthus. 
17. Alyssinae: Alyssum. 
18. Malcolmiinae : Anastatica, Malcolmia. 
19. Hesperidinae : Hesperis, Matthiola. 
20. Moricandiinae : Conringia.

Cryptadenia Meissn. Thymelaeaceae. 5 sp. Cape Col. 
Cryptantlms Otto et Dietr. Bromeliaceae (1). 6 sp. Brazil. Cultivated 
for their variegated leaves. 
Cryptocarya R. Br. Lauraceae (11). 40 sp. trop. and subtrop. The 
fruits of C. moschata Nees et Mart, are known as Brazilian nutmegs, 
and used as spice.
