tanist, and author of a splendid work on succulent 
plants). ORD. Bromeliacem. А genus of greenhouse 
Succulents, with elegant foliage and ornamental habit 
growth, usually stemless. There are about half-a- 
dozen species, natives of Brazil. They are best grown 
ith Agaves, and thrive well in a mixture of two parts 
; and one part vegetable mould, to which a little 
d may be added. Perfect drainage is essential, and 
water must be liberally applied during summer ; buf in 
winter, a very small quantity will suffice. Propagated 
by suckers.

six species of epiphytal orchids, from the Pacific Islands 
and New Zealand. They have small flowers, crowded into 
sessile heads; the lateral sepals and foot of the column 
forming a chin. E. mucronata (sharp-pointed) and E. 
autumnalis (autumnal) are two greenhouse species, from 
New Zealand. For cultivation, see Oncidium. 
EARTH. See Soil. 
EARTHING-UP. A term used to represent the 
process of drawing the existing, or applying additional, 
soil in ridges round the stems of kitchen-garden crops, 
or other surface-rooting plants, requiring more space for 
the development of the leaves than for the roots. It is 
performed in this case in order to concentrate the soil 
where it is most required. Earthing-up round the stems 
of Celery and similar crops is practised mainly 
exclusion of light from the stems, and for the coi 
blanching obtained. The plan is also frequently adop 
іп winter, for preserving the stems of plants from д
