332 CALYCIFLORJE. 



subpersistent tube ; segments deciduous, oblongo-ob- 

 tuse. Petals 5, scarcely longer than the calyx. Sta- 

 mens 10, with the filaments pilose at the base, and 

 the anthers eglandulose. Style capillary. Legume 

 compressed-plane, lance-shaped, acuminate at both 

 ends, 1 -celled, 2-seeded ; sutures closed, bursting 

 longitudinally at the middle of the valves : seeds 

 transversely oblong ; cotyledons 2-lobed. De Cand. 



There is only one species belonging to this genus. Name, 

 derived from a//Aa blood, and uXov wood, either from the colour 

 of the decoction, being that of dark Venous blood ; or, more 

 probably, from the red colour of the inner bark and wood.

A low spreading tree ; stem generally crooked and difformed, 

 seldom thicker than a man's thigh ; branches somewhat flexu- 

 ose, terete, albido-punctate ; in mountain and moist situations 

 unarmed ; in the plains or where the tree is stunted, furnished 

 with spines below the leaves. Leaves 2-4 from the same point 

 (an irregular rough tubercular prominence), pinnate, sometimes 

 dividing in a bipinnate manner at the lowest pair of leaflets ; 

 leaflets 4-paired, shortly petiolulated, obovate or obcordate. 

 Racemes at first about the length of the leaf, afterwards, as the 

 pods form, elongating. Flowers on pedicels half an inch in 

 length, yellow, slightly fragrant. Calyx deeply 5-partite; lobes 

 unequal, thin, membranaceous, purpurascent, deciduous ; tube 

 short, green, bell-shaped. Petals subequal, obovate, wedge- 

 shaped at the base, scarcely longer than the sepals. Stamens 

 alternately short, inserted, as also the petals on the inside of the 

 margin of the persistent tube of the calyx : anthers ovate. Ovary 

 lanceolate, compressed, 3-ovuled : style projecting beyond the 

 stamens and petals : stigma capitate-expanded. Pods com- 

 pressed, plane, lanceolar, acuminate at both ends, 1-celled, 2- 

 seeded, not opening at the sutures, but bursting longitudinally 

 by a division passing down through both of the valves. 



The Logwood is originally a native of Campeachy. It was 

 introduced from Honduras in 1715. Few plants have been so 

 completely naturalized. It thrives in every situation, with the 

 exception of the loftier mountains, and, with the Opoponax and 

 Casiiaw, occupies our plains. It is cut up into logs for exporta- 

 tion. The inner bark and the wood are red ; the latter is very
