Alliance IV. BALSAMALES, 
Essential Character. — Carpels not two polyspermous and diverging at the apex ; 
nor numerous, with a scale at the base of each ; but solitary, or few in number. Leaves 
and bark abounding in balsamic juice. 
This comprehends the principal point of the Terebintacese of Jussieu. It 
joins Gynobaseosse by Rutales, and Syncarposse by Rhamnales. 
Order CXVIII. AMYRIDACE^. 
Terebintace.®, Juss. Gen. 368. (1789) in part. — Amyride^, R. Brown in Congo, 431. 
(1818) ; Kunth in Ann. Sc. Nat. 2. 353. (1824). — ^TerebintacejE, trib. 5. DC. 
Prodr. 2. 81. (1825). 
Essential Character. — Calyx small, regular, persistent, in 4-5 divisions. Petals 4-5, 
with imbricated aestivation, or none. Stamens double the number of the petals, hypogynous. 
Ovary superior, 1 -celled, seated on a thickened disk; stigma capitate; ovules 2-6, pendu- 
lous. Fruit indehiscent, sub- drupaceous, or samaroid, or leguminous, 1-2-seeded, glandu- 
lar. Seed without albumen ; cotyledons fleshy ; radicle superior, very short. — Trees or 
shrubs, abounding in resin. Leaves compound, with pellucid dots. Inflorescence axillary 
and terminal, panicled. Pericarp covered with granular glands, filled with an aromatic 
oil. 
Affinities. The general structure of this order is that of Anacardiaceae, 
but in qualities it more nearly resembles Burseraceae. Kunth suggests its re- 
lation to Aurantiaceae, to which its dotted leaves, capitate stigmas, and peri- 
carps filled with reservoirs of oil, appear to approximate it. Myrospermum 
agrees with Samydaceae in the remarkable glandular marking of the leaves, in 
which the pellucid spaces are both round and linear, a very singular and un- 
common character, first pointed out by Brown. Congo, 444. 
Geography. Natives exclusively of the tropics of India and America, 
with the exception of one species found in Florida. 
Properties. Fragrant resinous shrubs. The Gum Elemi Tree of Nevis 
is, according to Dr. Hamilton, a plant related to the genus Amyris, which he 
calls A. ? hexandra. Prodr. FI. Ind. 35. The gum-resin, called Bdellium, is 
probably produced by a species of Amyris; the Niouttout of Adanson, accord- 
ing to Virey, Hist. Nat. des Med. 291 ; the Amyris Commiphora Roxb. 
according to Royle. Illustr. 176. The layers of the liber of a species of 
Amyris were found by Cailliaud to be used by the Nubian Mahometans as 
paper, on which they write their legends. Delile Cent.l^. Amyris toxifera 
is said to be poisonous. DC. Resin of Coumia is produced by A. ambrosiaca. 
Ibid. All the species of the genus Copaifera, and 16 are known, yield the 
Balsam of Copaiva ; but it is not in aU of them of equal quality. C. multijuga 
is said by Von Martius to afibrd the greatest abundance. Hayne in Linncea, 
1826. 418. The Balsam is known in Venezuela under the name of Tacama- 
haca. DC. Prodr. 2. 508. Myrospermum peruiferum, the Quinquino of 
Peru, produces a fragrant resin, in much use both for burning as a peiTume,
