FIG. 55. 



4 B. RACEMOSA (Jacq. fragm. p. 

 25. t. 16.) leaves with 4 pairs of 

 unequal-bided, oblong or oblong- 

 obovate, cuspidately - acuminated 

 leaflets, which are glanduliferous 

 at the base ; flowers in racemes ; 

 involucrum and calyx clothed with 

 fine tomentum ; calyx apparently 

 of 3 lobes, one free, and the 4 

 others joined by pairs. Tj . S. Na- 

 tive of Caraccas, at Guriepe, and 

 of Trinidad. H. B. et Kunth, nov. 

 gen. amer. 6. p. 312. Flowers 

 rose-coloured. Stamens 11-12. 



Racemose - flowered Brownea. 

 Shrub 4 feet. 



5 B. CAPITE'ILA (Jacq. fragm. 

 p. 26. t. 18 and 19.) leaves with 



from 2-7 pairs of oblong cuspidate leaflets ; flowers disposed in 

 dense heads ; ovary villous. Tj . S. Native of Caraccas, where 

 it is called Rosa-Macho. Flowers scarlet. 



Headed-Rowered Brownea. Shrub 6 to 10 feet. 



6 B. LEUCA'NTHA (Jacq. fragm. p. 20. t. 20 and 21.) leaves 

 with 6-8 pairs of oblong-lanceolate cuspidate leaflets, outer ones 

 the largest, lower ones small, ovate, cordate ; flowers disposed 

 in beads. l?.S. Native of Caraccas. Flowers white. 



White-fiov/ered Brownea. Shrub 8 feet. 



7 B. GRA'NDICEPS (Jacq. coll. 3. p. 287. t. 22. f. a. i. fragm. 

 t. 22 and 23.) leaves with usually 12 pairs of oblong-lanceo- 

 late glandless leaflets, ending in a long cuspidate acumen ; 

 branches and petioles pubescent ; flowers in dense capitate 

 spikes. Pj . S. Native of mountain woods at Caraccas, and in 

 woods near Cumana, also of Trinidad. H. B. et Kunth, nov. 

 gen. amer. 6. p. 313. Lam. ill. 575. f. 2. Corolla red. Sta- 

 mens 11. 



Large-headed Brownea. Clt. 1829. Tree 60 feet. 



Cult. All the species of Brownea are very splendid when in 

 bloom, and are therefore worthy a place in every collection of 

 stove plants. A mixture of loam, peat, and sand is a soil well 

 adapted for them, and care should be taken not to over water 

 the plants in winter, as too great a supply of water at that season 

 is almost sure to destroy them. Cuttings should be taken off from 

 ripened wood, and planted in a pot of sand, and placed under a 

 hand-glass in a moist heat, where they will strike root freely. 



CCXLII. DI'PTERIX (from &c, dls, double, and jrpi;, 

 pteryx, a wing ; in reference to the 2 upper lobes of the calyx, 

 which appear like 2 wings). Schreb. gen. no. 1161. D. C. prod. 

 2. p. 477. Baryosma, Pers. ench. 2. p. 278. 



LIN. SYST. Monadelphia, Octo-Decdndria. Calyx turbin- 

 ately tubular, 3-5-lobed, 2 superior lobes largest and wing- 

 formed, and nearly opposite, the lower ones smaller. Petals 5, 

 disposed into a papilionaceous corolla. Stamens 8-10, mona- 

 delphous, with the sheath or tube cleft longitudinally above. 

 Style ascending. Legume ovate, rather compressed, thick, 2- 

 valved, 1 -celled, 1 -seeded. Seed ovate-oblong, pendulous in the 

 cell, exalbuminous. Embryo straight, with thick cotyledons. 

 Trees, with abruptly-pinnate coriaceous leaves, and panicles of 

 flowers. 



SECT. I. COUMAROU'NA (Coumarou is the name of the tree in 

 Guiana). Aubl. guian. 2. p. 740. t. 296. CumarClna, Lam. ill. 

 t. 601 Baryosma, Gaertn. fruct. 2. t. 93. Heinzia, Scop. 

 Stamens 8. Lower segment of calyx undivided ; perhaps it is 

 simple, or perhaps composed of 3 joined sepals. 



1 D. ODORA'TA (Willd. spec. 8. p. 910.) leaves alternate, com- 



posed of 5-6 alternate leaflets ; petiole marginated. Tj . S. Na- 

 tive of Guiana, in woods. Coumarouna odorata, Aubl. 1. c. 

 Baryosma Tonga, Gaertn. 1. c. Flowers purple dashed with 

 violet, disposed in racemose panicles. The seeds of this tree 

 are the Tongo or Tonquin-beans, well known as giving a grate- 

 ful scent to snufF. The Creoles put them into chests in order 

 to drive away insects, as well as for their fragrance. 



Sweet-scented Tonquin-bean. Clt. 1793. Tree 60 feet. 



SECT. II. TARA'LEA (Tarala is the name of the tree in 

 Guiana). Aubl. guian. 2. p. 745. t. 298. D. C. prod. 2. p. 

 47S Bolducia, Neck. elem. no. 1342. Stamens 10; lower 

 segments of the calyx 3 or only one, which is trifid. 



2 D. OPPOSITIFOLIA (Willd. spec. 3. p. 910.) leaves opposite, 

 bearing 6-8 nearly opposite leaflets ; petiole wingless. Jj . S. 

 Native of Guiana, in woods. Taralea oppositifolia, Aubl. 1. c. 

 Baryosma oppositifolia, Pers. ench. 2. p. 278. Flowers in axil- 

 lary and terminal panicles, when blown their fragrance is very 

 diffusive. Petals violaceous. 



Opposite-leaved Tonquin-bean. Tree 60 feet. 



Cult. These trees grow best in a loamy soil, and ripened 

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

 glass placed over them, in a moist heat. 



Tribe X. 



CASSIE V /E (plants agreeing with Cassia in important charac- 

 ters). D. C. legum. mem. xiii. prod. 2. p. 478. Cassiae and 

 Cerceae, Bronn. diss. Lobes of calyx imbricate before expan- 

 sion (f. 57. a.). Petals perigynous, nearly equal (f. 56. b. f. 57. 

 b.), rarely somewhat papilionaceous, always imbricate in aestiva- 

 tion. Stamens distinct (f. 56. c. f. 57. c.), never with the fila- 

 ments concrete. Legume usually dry, and 2-valved (f. 56. e. 

 f. 58. g.). Cotyledons foliaceous, rarely fleshy. Leaves some- 

 times bipinnate, sometimes tripinnate, sometimes simply pinnate, 

 but rarely simple. The habit variable. This tribe will need 

 still to be further divided when the characters of the genera 

 are better known. Some of the genera have the sepals joined at 

 the base, or in a long tube, which is staminiferous at the apex. 



CCXLIII. MORI'NGA (Muringo is the Malabar name of 

 the first species). Burm. zeyl. 161. Lam. ill. t. 337. Gaert. 

 fruct. 2. p. 314. t. 147. Alandina, Neck. elem. no. 1293. 



LIN. SYST. Decdndria, Monogynia. Calyx of 5 nearly equal, 

 oblong, deciduous sepals, which are a little concrete at the base, 

 Petals 5, nearly equal, oblong, the upper one ascending. Sta- 

 mens 10, unequal, separate, sometimes 5 of which are sterile. 

 Style filiform, acute. Legume silique -formed, 3-valved. Seeds 

 trigonal, exalbuminous, fixed to the centre of the fruit. Embryo 

 straight, with thick oily cotyledons, which are inclosed within 

 the spermaderm through germination. Plumule none. Unarmed 

 trees, with impari-bipinnate or tripinnate leaves. Racemes pa- 

 nicled. Legume constantly composed of 3 carpels, which are 

 closely joined together, but which separate at maturity, leaving 

 only the seminiferous sutures. Perhaps a proper tribe. 



1 M. PTERYGOSPE'RMA (Gacrtn. fruct. 2. p. 314. t. 147.) le- 

 gumes triquetrous ; seeds trigonal, with the angles expanded 

 into wings ; leaves sub-bipinnate. fj . S. Native of the East 

 Indies and South America, where it has probably been intro- 

 duced. Guilandina Moringa, Lin. spec. 540. Hyperanthera 

 Moringa, Vahl. symb. 1. p. SO. Moringa oleifera, Lam. 1. c. 

 An6ma Moringa, Lour. coch. p. 279. Moringa Zeylanica, Pers. 

 ench. 1. p. 460. Rheed. mal. 6. t. 11. Rumph.amb. t. 74. and 

 t. 75. Flowers pale yellow, the upper petal whitish. The root 

 of this tree when young is scraped, and used by the inhabitants 

 of the places of its natural growth as horse-radish is in Europe, 

 having much the same sharp taste, as have also the seeds.
