476 CONNARACE.ffi — LEG-UMINOSjE. 



is procured from Elaphrium tommtosurri. Various other balsams and 

 resins are yielded by plants of this order. Amyris toxifera is said to 

 be poisonous. 



Order 63. — OoNNAEACEi®, the Connarus Family. {P oh/pet. 

 Perigyn.) Flowers bisexual, rarely unisexual. Calyx 5-partite, regu- 

 lar, persistent ; aestivation imbricate or valvate. Petals 5, inserted at 

 the base of the calyx. Stamens twice as many as the petals, inserted 

 with them, and doubtfully hypogynous ; filaments united at the base. 

 Ovary consisting of one or more separate carpels, each having a ter- 

 minal style and a dilated stigma ; ovules in pairs, collateral, ascend- 

 ing, orthotropal. Fruit follicular, dehiscing along the ventral suture. 

 Seeds solitary or in pairs, erect, with or without albumen, sometimes 

 arillate ; embryo with a superior radicle, remote from the hilum, and 

 cotyledons, which are either fleshy or leafy. — Trees or shrubs, with 

 compound, alternate, exstipulate leaves, which are not dotted. They 

 are tropical plants, and according to Endlicher are common in America. 

 Some of them have febrifugal properties. Omphalobium (Agelaea) Lam- 

 berti is said to furnish Zebrarwood. This order, as well as the orders 

 Anacaxdiacese and Amyridaoese, are by many considered truly hypo-, 

 gynous, and as belonging to Thalamiflorse. Lindley includes them in 

 his Eutal alliance. Genera 12, species 140. Examples — Connarus, 

 Omphalobium, Onestis. 



Order 64. — Lbguminos.s! (Fabacese of Lindley), the Pea and 

 Bean Tribe. {Polypet. Perigyn.) Calyx 5-partite, toothed, or cleft 

 (figs. 700, 701 c c), with the odd segment anterior ; segments often 

 unequal and variously combined. Petals 5 (figs. 700, 701), or by 

 abortion, 4, 3, 2, 1, or 0, inserted into the base of the calyx, some- 

 times equal, but usually unequal, often papilionaceous, with the odd 

 petal superior (fig. 701 e). Stamens definite or indefinite, usually 

 perigynous, distinct, or monadelphous or diadelphous (fig. 701, t) or 

 rarely triadelphous ; anthers bilocular, versatile. Ovary superior, 

 1-celled, consisting usually of a solitary carpel (fig. 701 o), sometimes 

 of 2-5 ; ovules 1 or many ; style simple, proceeding from the upper 

 or ventral suture ; stigma simple (fig. 701 s). Fruit a legume (figs. 

 536, p. 301 ; 565, p. 313 ; 702), or a drupe. Seeds solitary or several 

 (fig. 702), sometimes arillate, often curved (fig. 703) ; embryo usually 

 exalbuminous, straight, or with the radicle bent upon the edges of the 

 cotyledons (figs. 465, p. 258; 612, p. 340), which are either epi- 

 geal or hypogeal (p. 536) in germination (fig. 704), and leafy (Phyllo- 

 lobese), or fleshy (Saroolobese). — Herbaceous plants, shrubs, or trees, 

 with alternate usually compound leaves, having two stipules at the base 

 of the petiole (fig. 209, p. 98), and two at the base of each leaflet in 

 the pinnate leaves. Pedicels usually articulated. The flowers are fre- 

 quently papilionaceous (fig. 316, p. 205), and the fruit is commonly 

 leguminous (figs. 556, p. 307; 565, 566, 567, p. 313), and by the
