404: STATISTICS OF THE ORDER CRUCIFERA. 
also reported as being found in certain counties which have no 
seacoast. The Cochlearias (Scurvy-grasses) are found, at least 
most of their varieties, as C. officinalis, C. danica, etc., growing 
in muddy rills in our mountainous districts. Beautiful specimens 
of C. officinalis were gathered from the channel of the Ribble, in 
Ribbledale, above Settle, in Yorkshire. Forms from much greater 
altitude than the above, collected about the same time and in the 
same district, may have been reduced forms of C. anglica. This 
hint is thrown out that those who can may investigate the sub- 
ject. The latter-mentioned plant is reported from Derby and 
other inland counties. Several maritime plants of other families 
occupy elevated or alpine situations, and their habitats are both 
littoral and rupestral. Subularia is entirely aquatic, growing 
under water; Nasturtium officinale and N. amphibium partake 
more or less of the same character. The common Watercress 
grows best in water, and the Yellow-cress (N. amphibium) grows 
in places where water is close by, if not m the water. Cardamine 
amara is associated with these: C. pratensis is a pascual as well 
as a palustral plant; it grows where the Cowslip is found. 
Lepidium Draba, Armoracia rusticana, and Barbarea vulgaris grow 
in rather moist places, but they are not confined to meadows. 
The sylvan and septal plants of this Order are Dentaria, in woods 
only ; Sisymbrium Alliaria and Cardamine sylvatica, in woods and 
hedges, usually in the latter, because hedges are more common 
in England than woods are. Cardamine amara grows in boggy 
woods. A large portion of the Crucifere grows on rubbish or 
near homesteads, and such like localities. Shepherd’s Purse is 
one of these which follows man, and seldom strays far from the 
scenes of his labours. Coronopus Ruellit and C. didyma are also 
viatical (wayside) or rubbish-loving plants ; so also are Sisymbrium 
_ joficinale and Horse-radish ; Cardamine hirsuta is in wet places. 
Nasturtium sylvestre usually grows near water, or where water 
has been, about roadsides, or in rubbishy spots. Lepidium Smithii 
(ZL. hirtwm?) grows on_banks, where also are occasionally found 
Arabis hirsuta and Turritis glabra. The agyrarial or field plants 
are the Brassicas and the Mustard plants, Thlaspi arvense, Iberis 
amara, Lepidium campestre, Draba verna, Camelina sativa, Si- 
symbrium thalianum, S. Sophia, Erysimum cheiranthoides, and 
Raphanus Raphanistrum. Several of these, as Draba verna, grow 
on walls, and several on rubbish as well as in fields, such as Sisym-
