380 NATURAL HISTORY OF PLANTS. 
are often similarly useful. Sssoo wood is that of the Indian species 
of this genus, of the same specific name. Senegal ebony is D. melan- 
oxylon.' A large number of hard coloured woods, very incorruptible, 
from tropical America are produced by Dalbergia or the neighbouring 
genera Vatairea, Centrolobium, Cyclolobium, Tipuana, Macherium, &c., 
though it is impossible to refer each kind to its producing genus. 
This is the case with the true Palissandre wood, or violet-ebony, and 
probably the so-called Saint-Martin and Prefontaine woods of Guiana. 
In India the Dalbergias’ yield good woods, especially D. latifolia, 
heterophylla, and ferruginea; but it is hardly possible to refer each 
commercial kind to its proper species. Centrolobium tomentosum 
Bentu., of Guiana, is also mentioned for the value of its wood. The 
Gaiac of Guiana is not Guatacum sanctum (of the order Zygophyllacee) 
but Coumarouna odorata, the Tonquin-bean Tree ; its hardness makes 
it difficult to work. The members of Lonchocarpus often attain a 
great height. The wood of Z. sericeus from tropical America and 
Asia, resembles that of the Lemon-tree. The “Ccwr-dehors” (heart 
outside) of Guiana, in which interlacing fibres form a heartwood 
and alburnum of equal strength, is Diplotropis guianensis Buntu. ; 
the Boco is Bocoa provacensis.. The Cam-woods are produced by 
several African Baphias.’ The Panacocco’ are due some to American 
species of Ormosia or Baracaras, with a hard blackish heartwood ; 
others to Zbounatea or Swartzia (figs. 201, 202), of which several are 
used in building, while some furnish arcadas; these are the thin 
projecting ribs removed from the trunk and termed dozs-pagaye, on 
account of certain of their uses. The Jmmortelle or Erythrina wood 
is of a weak spongy consistency, as also in certain Sesbanias and 
notably in the species of Aschynomene, such as 4. aspera.’ In this 
aquatic species the stem becomes cellular and spongy, and very 
light; it is hence used to make light head-dresses, children’s toys, 
angolensis ; the Tender Red Sandal or Tender 
Coral wood of the Antilles to P. Draco and 
gummifer. 
1 Brya Ebenus P. Br. is said to give the 
Ebony or Grenadilla wood of the Antilles.
