The leaves are bipinnate with about 10 leaflets on each 
pinna, these are 3—9 mm. long, oblique, hairy and when 
the sun shines they are directed upwards. Older branches 
have white bark and are covered with prickles. 
Tbe year-shoot is branched. During the same year each 
axil gives off either an inflorescence or a branch, or two bran- 
ches, or a branch and an inflorescence. The 
longest year-shoot branches are about 15 
centimetres long at the beginning of June 
and only the outermost 2 centimetres are not 
fully lignified. The year-shoot branches bear 
many leaves which often subtend inflores- 
cences, but apparently no new branches. 
The year-shoot branches cannot be termed 
assimilating shoots as they are persistent. 
Prosopis flowers from May to July. The 
inflorescences are long racemes with small 
flowers. The fruit is a fleshy pod 3—4 
centimetres long. 
Rig’ 37) 5 Phodopis The leaf is isolateral in structure (fig. 
Stephaniana. Sec- 937). The epidermis contains tannin and 
en the has stomata on both surfaces; 6—7 layers 
of palisade cells fill up the whole leaf. 
The veins have bast sheaths on both sides. “Speichertrach- 
eiden” are present. 
Zollikoferia acanthodes Bois. 
is said to be a stunted thorny shrub with forked angular 
branches and with thorn-like short-shoots. A few ovate or 
oblong leaves occupy the base of the branches, they are 
thickly coated with white spines and soon fall off. (From 
BoIssiER fl. orientalis.) 
Atraphaxis spinosa L. 
A strongly branched shrub never exceeding a height of 
one metre. The leaves are shortly petiolate, circular-ovate, 
rather thick and about one centimetre long. The bark is
