brown spots at the base of the column, solitary ; sepals ligulate, 
acuminate, sometimes undulated at the margin; petals oblong- 
apiculate, with finely-toothed margins; lip cuneate at the base,

species of annual or biennial, branched, slender, smooth 
or pilose herbs, allied to Cakile. Racemes opposite the 
leaves, erect, elongated. Leaves either pinnatifid or entire. 
They are all of easy culture in common garden soil.

tantalised with finding many salt springs, his party had just 
met with an ample Supply of fresh water; this welcome 
refreshment, of which he speaks feelingly in his book, 
seems to have suggested the name) Овр. Leguminose. 
Greenhouse evergreen sub-shrubs, with alternate, simple, 
sinuately toothed, or entire leaves, They are mostly trained 
on globe and other trellises, with excellent effect, the whole 
trellis being lighted up with the brilliant beauty of their 
flowers, slightly toned down by the pleasing forms and 
refreshing variation of the leaves.

ones anging over and partly hiding the pots. They all 
grow freely Ш а mixture of peat snd E fibry, but not toc 
rough, with a large proportion of sharp silver sand. The 
nage should also be liberal and the pots scrupulously 
clean. In potting, the soil should be pressed firm, as for 
Heaths, Azaleas, and other hard-wooded plants. Loose 
potting kills thousands of choice plants every year. A 
certain degree of solidity is needful in the potting of hard- 
wooded plants, to enable the roots to grip the fresh soil. 
If they miss doing so, the new soil sours, the roots remain 
where they are, or the extremities—their most vital parts— 
rot off, and the plants languish and die. If the soil is used 
m а Proper condition as regards dryness, it is hardly pos- 
sible to overdo the compression with the fingers and hands. 
е best time to pot these plants is just as the shoots begin 
to break afresh. They may finish their growth in a common 
greenhouse, or have a little more heat during their growing 
Period. At the end of summer and during the early 
autumnal months, they may be placed out of doors, ina _ 
sheltered place, care being taken to stand the pots on a 
Worm-proof bottom. Early in the autumn, the plants 
should be taken under glass, before being soaked ог sod- 
dened with heavy rains. T s E sag hog
