362 LXXIII. TEEEBINTHACE^. 



pression of the ovaries, which 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.). FBUIT usually 

 superior, rarely inferior (Holigama), 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. EMBRYO exalbuminous ; cotyledons plano-convex ; 

 radicle more or less curved, superior or inferior. 



[The following is the new arrangement of Anacardiaceoc (Terebinthacece) in the 

 ' Genera Plantarum ' : 



TKIBE J. ANACARDIEJE. Ovary 1-oelled. 



A. Ovule usually suspended from a basilar funicle. 



* Sepals and petals not accrescent. Rlius, Pistacia, Sorindeta, Bnchanania, Comocladia, 

 Mangifera, Anacardium, Boitea, Gluia. 



* * Sepals or petals accrescent. Melanorrlicea, Stvintonia, Loxostylis. 



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



* Leaves compound. Calyx not accrescent. Schinus, tfolenocarpus, Smodinyium, Odina. 



* * Leaves compound. Calyx accrescent. Aatronium, Parlslmi. 



* * * Leaves simple (or pinnate in Manria).Seniecarp-us, Corynucarpus, Drimycarpu*, 

 Maiiria, Holiyana, Duvana. 



TRIHE II. SPONDIEJ;. Ovary "2 5-celled. Ovules pendulous. Spondias, Dracontomeltim, 

 Sclerocarya, Harpephyllum, &c. Eo.J 



Terebinthacece approach liosacete, tribe Arnyytfaleee, iu their habit, woody stem, alternate leaves, peri- 

 gynous insertion of their polypetalous corolla and (sometimes polyandrous) audroeciuin ; iu the solitary 

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

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

 binthacece are allied to Juylandea, which, like them, have diclinous flowers, a one-celled one-ovuled ovary, 

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

 also closely allied to Connaracete and Zanthoxylece, and have therefore been placed in the same class. 

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

 ventral raphe. Connnracece differ in their distinct carpels with two collateral and erect ovule?, and 

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

 less copious albumen. 



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

 beyond this zone, so that they are rare in the Mediterranean region, 1 in South Africa, North America, and 

 Australia, where however, five genera occur. 



Terebinthacece yield medicinal substances, edible fruits, [fine varnishes, ED.], and many woods useful 

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



1 This refers to genera and species, and not to individuals ; for Pistacia of three mpecies abounds, as do several 

 of R/ius, in some districts of the Mediterranean. Eu.
