a vegetable. The plant is perennial and here merely men- 
tioned as entitled to extended culture in grouping this with 
other stately plants. Several other species are worthy of 
cultivation. 
Cynosurus cristatus, L. 
The Crested Dogstail-Grass. Europe, North Africa, "West 
Asia. A perennial grass, particularly valuable as with- 
standing drought, the roots penetrating to considerable 
depth. The stems can also be used for bonnet plaiting. 
Though inferior in value for hay this grass is well adapted 
for permanent pasture, as it forms a dense turf without 
suffocating other grasses or fodder-herbs. 
Cyperus corymbosus, Eottboell. 
India. This stately perennial species may be chosen to 
fringe our lakes and ponds. It is extensively used for mats 
in India. 
Cyperus Papyrus, L. 
The Nile Papyrus. Though no longer strictly an utilitarian 
plant, as in ancient times, it could scarcely be passed on this 
occasion, as it ought to become valuable in horticultural 
trade. Its grand aspect recommends it as very decorative 
for aquatic plantations. 
Cyperus Syriacus, Parlatore. 
The Syrian or Sicilian Papyrus. This is the Papyrus-plant 
usual in garden cultivation. The plants in our Botanic 
Garden attain a height of 8 feet, but suffer somewhat from 
frost. Other tall Cyperi deserve introduction, for instance 
C. giganteus, Eottboell, from "West India and Guiana, these 
kinds of plants being hardier than others from the tropics. 
I have not ventured to recommend the introduction of 
Cypens esculentus, L., a Mediterranean species, remarkable 
for its sweet tubers, known as Earth Almonds. It is stolo- 
niferous like the allied Cyperus rotundus, L., which has 
invaded the culture ground of many countries as an obnoxious 
irrepressible weed. The tubers of Cyperus esculentus con- 
tain about 16 per cent. oil.
