and Miscellaneous Particulars. 
genus are surmounted by the five fertile ones, (Vahl.) Cuttings root best under a hand-glass in 
sand. 
981. Hoffmanseggia. Named by CavaniUes, after John Charles HofFmansegg, whom he calls a distinguished 
naturalist. It may be with some propriety be employed to commemorate the merits of the present distinguish- 
ed Count HoflFmansegg. Cuttings, somewhat ripened, root under a hand-glass in sand. 
982. Adenanthera. From «S»5v, a gland, and «v3->?«ai, an anther. The essential character of the genus is to 
have each anther tipped with a gland. Large cuttings, with the leaves not shortened, root best in a pot of 
sand plunged in heat under a hand-glass. (^Bot. Cult. 13.) 
983. Cadia. Contrived by Forskahl, from the Arabic name of the plant, — qadhy. 
984. Prosopis. One of the names under which Dioscorides described the Arctium Lappa. The present plant 
has no sort of resemblance to that of the ancients. It is a leguminous plant, and the pods are eaten as a con- 
diment in India. 
985. Hcematoxylon. From a;^at, blood, and |uXev, wood, in allusion to the color of an infusion of its wood. 
The logwood of commerce. This is a crooked stemmed low tree, with pinnate leaves, originally from the Bay of 
Campeachy ; the inner bark and wood red, the latter dark and very hard. It makes an excellent fence, the 
smaller shoots are cut for hoops, and the stems for exportation for dying. The gum is a gentle subastringent. 
In our stoves it grows well in loam and leaf-mould, kept rather moist, and cuttings root in sand under a hand- 
glass in heat. 
986. Copaifera. This tree is so called from bearing the drug Copaiba, which is the name given to the tree 
itself by the people of Brazil. Beaume de Copahu, Fr., Kopaiva Balsam, Ger., Balsamo del Coppaiba, Ital. 
This is a lofty elegant tree, with a handsome branching head, the extreme branches flexuose at the axils, the 
bark ash-colored, and the leaves pinnate. It grows abundantly in the woods of Tolu, near Carthagena, and of 
Quito, in Brazil. The copaiba balsam of the shops is procured by wounding or boring these trees to the pith, 
near the base of the trunk, when it flows abundantly, in the form of a clear colorless liquid, which is thick- 
ened, and acquires a yellowish color by age. The operation is performed two or three times in the same yearj 
and-from the older trees the best balsam is obtained. 
Copaiba balsam is stimulant, diuretic, and gently purgative. It has been recommended in pulmonary com- 
plamts, and it certainly affords considerable relief in haamorrhoidal affections. {Thompson's London Dispensa- 
tory, 265.) It may be increased by ripened cuttings in sand under cover.
