a brilliant crimson, having all tho richness of velvet ; while the wings and keel are of a bright rose-colour. Tliis 
pea was introduced in 1680, by Dr. Morison, who received it from Tangiers, and it has remained in cultivation 
ever since. Seeds may be procured at any seed-shop, and the plants require the same care as those of the 
sweet pea.

Description, &c. — The flower consists of a bright red standard with white wings and keel. This pea is a 
native of the south of Europe, and when it was first introduced, it was called the Spanish pea, because its seeds 
were sent from Spain to the Botanic Garden, Chelsea, in 1739. It is of rather lower growth than the common 
sweet pea, seldom rising above three feet high, but it may be sown and treated in the same manner.

Description, &c. — This plant is grown more for its singularity than its beauty. The flowers which appear 
above ground are pink tinged with blue ; but the underground stems bear flowers and pods, which are quite 
perfect, and exactly similar to those above-ground, except that every part of the underground plant is whitish. 
The plant is much smaller than any of the other peas, and rarely grows above a foot high. Seeds may be had in 
any of the seed-shops, and they should be sown in February in very light soil, to allow the underground shoots 
to make their way. The plants when nearly full grown are generally earthed up.

Description, &c. — The flowers are bright blue, with a faint stain of pink between the standard and the 
wings. The pods are winged with a deep groove down the back. The plant seldom grows above two feet high, 
and is much branched. There is a variety with white flowers. This species is a native of France and Spain, 
where it is grown for feeding horses, and hence its specific name of " sativus," which signifies cultivated. The 
flour made from the peas when ground, if mixed with an equal quantity of wheat flour, makes excellent bread, but 
taken alone it produces an extraordinary rigidity of the muscles. In the year 1671, a famine having occurred in 
Wirtemberg on account of the failure of the wheat crops, the peasants made their bread entirely of this flour. 
After living upon it for some days, some of them began to find themselves strangely afiected ; one man when he 
bent his arm could not straighten it again ; and a neighbour who laughed at him found that he could not bring 
his mouth back to its original form, but that he was doomed to wear an eternal grin. The medical men applied
