belonging to the same tuft. Stems reach a height of 100 feet and a 

 circumference of 33 inches; the joints are occasionally as much as 

 18 inches long and the walls an inch thick [Dr. Trimen]. Locally- 

 much used for rural buildings, furnishing posts, rafters, flooring 

 material and shingles [Brandis]. Buckets and many other domestic 

 utensils are readily made of this Bamboo. D. criticus of Burmah 

 attains a height of 30 feet, and ascends to 3,000 feet [Kurz]. 



Dendrocalamus Hamiltoni, Nees. 



Himalayas, between 2,000 and 6,000 feet. The Tama-Bamboo. 

 Height reaching 60 feet. The young shoots of this stately Bamboo 

 are edible in a boiled state [Hooker]. It endures great cold as well 

 as dry heat [Kurz]. D. Hookeri (Munro) is a closely allied 

 species. 



Dendrocalamus longlspathus, Kurz. 



British Burma, where with D. calostachyus (Kurz) it ascends to 

 about 3,500 feet; the former rises to a height of 60 feet. D. mem- 

 branaceus (Kurz) attains there nearly the same height. 



Dendrocalamus membranaceus, Munro. 



Burma. To 50 feet high. Seeds of this species, which germinate 

 readily, and of several other kinds of Bamboo were extensively dis- 

 tributed in Australia by the writer of this work. Bamboo seedlings 

 should have good drainage and an open soil, which should just be 

 kept moist but not wet; over-watering is apt to make them damp off 

 [Gamble]. 



Dendrocalamus strictus, Nees.* 



India, extending to Burma. Grows on drier ground than 

 Bamboos generally. Its strength and solidity render it fit for many 

 select technic purposes. It attains a height of 100 feet, and occasion- 

 ally forms forests of its own. It endures great cold as well as dry 

 heat [Kurz]. Useful for the consolidation of embankments on 

 account of the network of fibrous root [Fernandez]. Readily raised 

 from seed. This and D. Hamiltoni are almost annually seeding 

 [Gamble], which is exceptional among Bambusaceae. 



Desmodium acuminatum, De Candolle. 



Eastern North- America. With D. nudiflorum (D.C.) mentioned 

 by C. Mohr as a nutritive plant for stock, and particularly adapted 

 for forest-soil. 



Desmodium triflorum, De Candolle.* 



In tropical regions of Asia, Africa and America. A densely 

 matted perennial herb, alluded to on this occasion as recommendable 

 for places too hot for ordinary clover, and as representing a large
