362 LXXIII. TEEEBINTHACE^. 



pression of the ovaries, whicli have become confluent with the fertile one ; ovules 

 solitary, pendulous, or broadly adnate to the wall of the cell, or suspended to a basal 

 ascending funicle, micropyle superior and raphe dorsal, rarely erect with the micro- 

 pyle inferior and raphe ventral {Anacardium, Mangifera, &c.). Feuit usually 

 superior, rarely inferior {Eoligarna), free, or girt by a receptacular cup, sometimes 

 seated on a broadened pyriform fleshy receptacle {Anacardium), usually a drupe, 

 indehiscent, or with a dehiscent endocarp, rarely nut-like {Anacardium). Seed 

 erect, horizontal or inverted ; testa membranous, sometimes confluent with the endo- 

 carp ; hilum usually ventral. Embeto exalbuminous ; cotyledons plano-convex ; 

 radicle more or less curved, superior or inferior. 



[The following is the new arrangement of Anacardiacece {Terebinthacew) in the 

 ' Genera Plantarum ' :— 



Tribe I. Anacaediej;. — Ovary 1-celled. 



A. Ovule usually suspended from a basilar funicle. 



* Sepals and petals not accrescent. — Blius, Pistacia, Sorindeia, Buchanania, Gomocladia, 

 Mangifera, Anacardium, Bouea, Qluta. 



* * Sepals or petals accrescent. — MelanorrJicea, Swintmiia, Loxostylis. 



B. Ovule suspended from above the middle of the cell. 



* Leaves compound. Calyx not accrescent. — Scliinus, Bolenocarpiis, Sinodingium, Odina. 



* * Leaves compound. Calyx accrescent. — Astroniutn, Parishia. 



*** Leaves simple (or pinnate in Mauria).—Semecarpus, Gorijnocarpus, Drlmy carpus, 

 Maitria, Holigana, Buvava. 



Tribe II. Spomdieji. — Ovary 2— 5-celled. Ovules pendulous. Spondias, Dracontomelum, 

 Sclerocarya, Sarpephyllum, &c. — Ed.J 



Terebintliaceee approach JRosacece, tribe Amygdalem, in their habit, woody stem, alternate leaves, peri- 

 gynous insei-tiou of their polypetalous corolla and (sometimes polyandrous) androecium ; in the solitary 

 carpel, usually drupaceous fruit, and exalbuminous seed. They approach some Leguminonm in the same 

 points, and also in the frequently monadelphous stamens, and in the more or less curved embryo. Teire- 

 hinthacecB are allied to Juglandem, which, like them, have diclinous ilowers, a one-celled one-ovuled ovary, 

 drupaceous fruit, exalbuminous embryo, woody stem, and alternate usually pinnate leaves. They are 

 also closely allied to Connaracece and Zanthoxyhce, and have therefore been placed in the same class. 

 JBurseracets scarely differ save in the two-ovuled ovarian cells and the ovules with superior micropyle and 

 ventral raphe. Connnracem diifer in their distinct carpels with two collateral and erect ovules, and 

 their capsular fruit. Finally, Zanthoxylecs chiefly differ in their seed, which is furnished with a more or 

 less copious albumen. 



TerehinthactcB are frequent in the intertropical zone of both continents ; they diminish rapidly 

 beyond this zone, so that they are rare in the Mediterranean region,', in South Africa, North America, and 

 Australia, where however, five genera occur. 



Terehmthacece yield medicinal substances, edible fruits, [fine varnishes, Ed.], and many woods useful 

 to dyers and cabinet-makers. The principal species are the following : — 



' This refers to genera and species, and not to individuals ; for Fistacia of three species abounds, as do several 

 of Rhus, in some districts of the Mediterranean. — Ed.
