CALYCIFLORAE. 
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. — JJe Cand. 
There is only one species belonging to this genus. Name , 
derived from a i,aa blood , and t'u'kov 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. 
1. Haematoxylon Campechianum. Campeachy Log- 
wood. 
Lignum Campechianum, Cat. Car. III. t. 66. — Sloane, II. t. 
10. f. 1 — 4. — Hamiatoxylon spinosum, Broivne, 221. 
HAB. Common. 
FL. After the May and Autumnal rains. 
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, purpuraseent, 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 capitato-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 
Cashaw, occupies our plains. It is cut up into logs for exporta- 
tion. The inner bark and the wood are red ; the latter is very
