are rings of large translucent cells 
between which there are very nar- 
row bands of chlorophyllous tissue. 
Astragalus unifoliatus Bge. 
A shrub attaining a height of 
until 0,; metre. It is strongly 
branched, the branches being spread 
out and crooked. The bark of 
older branches shows a network 
or dibres. The green parts are 
densely coated with greyish or 
whitish hairs. The leaves are small 
and pinnate with four leaflets at 
the beginning of the vegetative sea- 
son, but later they are ternate or 
only single-leaved. Towards summer 
most of the leaflets fall off and 
the rachis remains like a wooden 
peg 0,5—2 centimetres long, later 
during the summer it likewise 
withers. The leaflets are elliptical 
or lanceolate and small, generally 
no more than a centimetre long, 
but occasionally they may be 2 
centimetres. The stipules are con- 
nate, clasping the branch. 
Part of a young year-shoot is 
shown in fig. 33 where the bran- 
ching is seen. Sometimes the bran- 
ches again produce lateral shoots. 
These branches are assimilating 
shoots which do not persist. In 
their place one or more new shoots 
will arise next year so that here 
again, sometimes in a very marked 
degree, we find branches arranged 
in bunches.
