the pinnae sometimes abruptly, sometimes impari-pinnate, and 

 with a pedicellate gland at the base of the petiole on one or 

 both sides. Racemes opposite the leaves. Flowers yellow. 



1 H. FALCA'KIA (Cav. icon. 4. t. 392.) stems decumbent, 

 hardly suffruticose ; leaves with 3-6 pairs of pinna 1 , with an odd 

 one, each pinna bearing 3-6 pairs of oval-oblong, glaucous

 tmn ; legumes straight, villous. % . S. Native of South America, 

 near Port Desire. Flowers yellow. 



Trifoliate Hoffmanseggia. PI. \ foot. 



3 H. PROSTRATA (Lag. in litt. ex D. C. prod. 2. p. 485.)

 Caesalpinia pilosa, Ruiz et Pav. in herb. Lamb. Petioles and 

 peduncles very pilose. Root tapering. Flowers yellow. 



Pilose Hoffmanseggia. PI. -j foot. 



Cult. The species of this genus are smnll herbaceous plants. 

 They grow best in a mixture of peat and loam, and are increased 

 by seeds, which will ripen in this country. 



CCLV. MELANOSTI'CTA (from yutXne, melas, black, and 

 a-iKTos, stictos, marked ; in reference to the leaves and calyxes 

 being beset with black glands, which have the appearance of 

 black dots or marks). D. C. legum. mem. xii. prod. 2. p. 485. 



LIN. SYST. Decandria, Monogynia. Sepals 5, nearly equal, 

 }oined together at the base into a short permanent tube, but free 

 at the apex, and deciduous. Petals 5, nearly equal, elliptic, 

 attenuated at the base, length of the calyx. Stamens 10, dis- 

 tinct ; filaments rather villous at the base from branched hairs. 

 Legume compressed, ovate-oblong, hairy, 4-ovulate. A humble 

 shrub, native of the Cape of Good Hope, with somewhat fas- 

 cicled roots, some of which are cylindrical, and others thickened 

 into tubers. Leaves bipinnate, with 2 pairs of pinnae, each pinna 

 bearing 6-8 pairs of leaflets, with the terminal leaflet elongated. 

 Stipulas pinnatifid. Racemes elongated. This genus is very 

 nearly related to Pomaria, but the fruit is not sufficiently known.

 Cape of Good Hope. Burch. cat. no. 2345. Csesalpinia Mela- 

 nosticta, Sprcng. syst. append, p. 16D. Leaves and calyxes 

 dotted with hlack sessile glands, whence the generic name. 



Bitrchell's Melanosticta. Shrub I foot. 



Cult. See Hoffmanseggia for culture and propagation. The 

 plant is increased by dividing at the root. 



CCLVI. POMA'RIA(in honour of Pomar, physician to 

 Philip III.' of Spain). Cav. icon. 5. p. 1. t. 402. D. C. prod. 2. 

 p. 485. 



LIN. SYST. Dec&ndria, Monogynia, Sepals 5, joined at the 

 base into a short tube, 5-cleft at the apex (f. 56. a.), the seg- 

 ments deciduous. Petals 5 (f. 56. &.), on short claws, the up- 

 permost one concave, and shorter than the rest. Stamens 10, 

 free (f. 56. c.), decimate, hairy at the base (f. 56. c.). Style 

 filiform, crowned by a capitate stigma. Legume oblong, com- 

 pressed (f. 56. d.), 2-valved, 1 -celled, 2-seeded (f. 56. e.). Seeds

ovate. A shrub, with abruptly 

 bipinnate leaves, pinnatifid stipu- 

 las, and axillary racemes of flowers. 

 Branches, calyxes, and corollas 

 beset with glands. This genus 

 is very nearly allied to Hoffman- 

 seggia. 



1 P. GLANDULOSA (CaV. 1. C.) 



Tj . S, Native of New Spain, near 

 Qtieretaro, and of North America, 

 on the banks of the Canadian river. 

 Flowers yellow. 



Glandular Pomaria. Shrub 6 

 feet. 



Cult. See Hoffmanseggia for 

 culture and propagation. 



CCLVII. H^EMATO'XYLON (from c>a, haima, blood, 

 and v\ot', xylon, wood ; logwood is well known for its red 

 colour). Lin. gen. no. 525. Lam. ill. t. 340. D. C. prod. 2. 

 p. 485. 



LIN. SYST. Decandria, Monogynia. Calyx 5-lobed, the tube 

 permanent, but the lobes are deciduous, oblong, and obtuse. 

 Petals 5, hardly longer than the calyx. Stamens 10; filaments 

 pilose at the base ; anthers glandless. Style capillary. Legume 

 compressed, flat, lanceolate, acuminated at both ends, 1 -celled, 

 2-seeded, with the sutures indehiscent, but the valves burst lon- 

 gitudinally to relieve the seeds. Seeds transversely oblong. 

 Cotyledons 2-lobed. A tree, with unarmed branches, or with 

 spines under the leaves. Flowers racemose, hermaphrodite. 



1 H. CAMPECHIA'NUM (Lin. spec. 549.) Jj . S. Native of the 

 Buy of Campeachy at Honduras, and other parts of the Spanish 

 West Indies, but now cultivated in Jamaica and other West 

 India Islands, &c. Plench. icon. t. 329. Woodv. med. bot. p. 

 48. t. 17. Cat. car. 3. t. 66. Sloan, hist. 2. t. 10. f. 1-4. Leaves 

 abruptly-pinnate, in fascicles ; leaflets obovate, obcordate. 

 Flowers yellow. Logwood is generally crooked, and seldom 

 thicker than a man's thigh. It was first cultivated in Jamaica 

 in 1715 from seeds brought from the Bay of Campeachy. It 

 makes impenetrable and beautiful fences. Both the bark and 

 wood are gentle subastringents ; but the last excels, and adds a 

 sweetness to its virtue, which makes it more agreeable to the 

 palate. The wood is principally used in dyeing. 



Campeachy or Common Logwood. Clt. 1 732. Tree 20 ft. 



Cult. Logwood grows well in a mixture of sand and peat ; 

 and cuttings will root if planted in a pot of sand, with a hand- 

 glass placed over them in heat ; but the plants are generally 

 raised from seeds sent or brought from the West Indies. 



CCLVIII. PARKINSONIA (in honour of John Parkinson, 

 an apothecary of London, author of Paradisis Terrestris, 1629, 

 and Theatrum Botanicum, 1649). Plum. gen. 25. Lin. gen. no. 

 513. Lam. ill. t. 336. D. C. prod. 2. p. 485. 



LIN. SYST. Dcctindria, Monogynia. Sepals 5, equal, spread- 

 ingly reflexed. Petals 5, ovate, flat, upper one roundish, on a 

 long claw. Stamens 10, rather declinate, a little longer than the 

 claw of the superior petal. Style filiform, rather ascending. 

 Legume linear-oblong, acuminated at both ends, torose at the 

 seeds, but compressed between them. Seeds oblong, with the 

 endopleura tumid, and with a linear hylum. Embryo with ob- 

 long cotyledons, and an ovate radicle. A shrub, furnished with 

 solitary or tern straight prickles or spines. Leaves pinnate ; 

 leaflets usually deciduous or abortive. Petioles linear, very long, 

 winged. Racemes loose. Flowers beautiful yellow.
