XXX. LAGUNE'A (in honour of Andreas Laguna, a 

 Spanish physician and botanist of the sixteenth century. He 

 translated Dioscorides into Spanish). Cav. diss. 3. p. 173.

 cleft. Petals 5, spreading, with narrow claws. Anthers inserted 

 on the sides and top of the tube. Stigmas 5. Capsules 5-celled, 5- 

 valved, with a dissepiment in the middle of each valve, connected 

 with the central filiform permanent axis. This genus differs 

 from Hibiscus as Sida does from Mdlva. Flowers axillary, 

 solitary.

 lobed ; lobes oval-oblong, acuminate, toothedjwith very nar- 

 row recesses. O- H. Native of the Island of Bourbon.

lobed-leaved Lagunea. Fl. July, Aug. Clt. 1787. PI. 2 ft. 



2 L. ? TRI'COLOR ; pilose ; stem erect, simple ; leaves lan- 

 ceolate, acute, rather cordate at the base. Q. S. Native of 

 Sierra Leone. The corolla is of 5 petals of the same colour as 

 those of Hibiscus tribnum. Perhaps a distinct genus. 



Three-coloured-flowered Lagunea. PI. 3- foot. 



3 L. SINUA'TA (Horn. hafn. 645.) leaves cordate, 3-lobed ; 

 lobes oblong, acuminate, toothed, with wide recesses. 0. S. 

 Native of ? Perhaps a variety of L. lobata. L. angulata, Hortul. 

 Flowers purplish-white ? 



Scolloped-leaved Lagunea. Fl. July, Aug. Clt. 1817. PI. 2 ft. 



4 L. TERNA'TA (Cav. diss. 5. p. 279. t. 136. f. 2. under So- 

 Idndra,} lower leaves 3-parted ; lobes oblong, entire, middle one 

 very long; upper leaves somewhat halbert-shaped, elongated. 

 Q. S. Native of Senegal. Stem villous. 



Zerna/e-leaved Lagunea. PL 1 foot. 



5 L. ACULEATA (Cav. diss. 3. p. 173. t. 71. f. 1.) leaves 3- 

 parted, with oblong-linear, deeply-toothed lobes ; stem prickly, 

 tomentose. ? S. Native of Pondichery. Flowers yellow. 

 Stigmas red. Calyx ruptured longitudinally. This plant is 

 called Cattacacheree by the inhabitants of Pondichery. 



Prickly Lagunea. PL 1^ foot. 



Cult. Not worth cultivating except in botanical gardens. 

 The seeds require to be sown on a moderate hot-bed, and when 

 the plants are of sufficient size they should be shifted into other 

 pots, and then placed in the green-house or planted out in the 

 open border in a sheltered situation. 



XXXI. INGENHOUZIA (Ingenhouze, a Mexican bo- 

 tanist.) Moc. et Sesse, fl. mex. icon. ined. D. C. prod. 1. 

 p. 474. 



LIN. SYST. Monadelphia, Polydndria. Calyx naked, 3- 

 parted into ovate-lanceolate, acuminate lobes. Petals 5, with a 

 campanulate urceolus on the inside of the petals. Stamens in- 

 definite, monadelphous. Style 1. Fruit unknown. 



1 I. TRI'LOBA (Moc. et Sesse, fl. mex. icon. ined. D. C. prod. 

 1. p. 474.) $ , G. Native of Mexico. Herb resembling in 

 habit Gossypium. Leaves stalked, 3-lobed ; lobes ovate-lan- 

 ceolate, acute, entire. Pedicels L-flowered, opposite the leaves. 

 Flowers yellowish-red. 



Three-lobed-leaved Ingenhousia. PI. 2 feet ? 



Cult. The seeds of this plant will require to be raised on a hot- 

 bed frame, and when the plants are of sufficient size they should 

 be separated and planted singly in other pots, and after they have

recovered this shifting, they may then be placed in the stove 

 or greenhouse, where they will ripen their seed. 



XXXII. EURYA'NTHE (from evpvt, eurys, wide, and 

 f, anthos, a flower,) Cham, et Schlecht. in Linnaea. 3. 

 p. 206. 



LIN. SYST. Polydndria, Monogynia. Calyx 5-parted, di- 

 vided nearly to the base. Petals 5, twisted in aestivation. Sta- 

 mens indefinite, free ; filaments hardly connected at the base, 

 unequal ; anthers linear, 2-celled, fixed by the base, opening 

 longitudinally. Ovary superior, egg-shaped, 3-celIed, many- 

 seeded, fixed to the central column. Style simple, deciduous, 

 terminated by a simple stigma. Fruit 3-celled, 3-valved ; valves 

 with a dissepiment in the middle. A malvaceous herb, with 

 alternate digitately-parted leaves. This genus is allied to Gera- 

 niacece, but more closely to Malvaceae, but it differs materially 

 in the anthers being 2-celled, a circumstance which excludes it 

 from that order as it is now constituted. 



1 E. SCHIEDIANA (Cham, et Schlecht. 1. c.) O? I/- G. 

 Native of Mexico. Stipulas free. Racemes secund. Flowers 

 large, flame- coloured. 



Schiedes Euryanthe. PL 1 foot. 



Cult. This plant will grow in a mixture of loam and sand, 

 and it may either be increased by seed, or by cuttings, planted 

 under a hand-glass. 



ORDER XXXI. BOMBA'CE^E (plants agreeing with Bom- 

 bax, in many important characters,) Kunth, diss. malv. p. 5. 

 nov. gen. amer. 5. p. 294. D. C. prod. 1. p. 475. 



Calyx naked at the base or involucrated with a few bracteas 

 (f. 87. a.). Sepals 5, joined together into an urceolate-campanu- 

 late tube (f. 87. &.), sometimes truncate at the apex, sometimes ir- 

 regularly imbricated, sometimes somewhat valvately-connate, and 

 bursting laterally ; the aestivation is therefore doubtful. Petals 

 5, regular (f. 87. c.) or wanting, when present they are usually 

 convolute in aestivation, but sometimes imbricate. Stamens 5 ? 10- 

 15 or more ; filaments adnate to the base of the tube of the petals, 

 but separated into 5 bundles (f. 87. ./.); bundles containing 1 or 

 many anthers, sometimes intermixed with a few sterile threads. 

 Anthers 1-celled. Ovary of 5, rarely of 10 carpels, sometimes 

 these are nearly distinct, sometimes so closely connected as to ap- 

 pear a single fruit (f. 86. /. f. 87. g.), opening variously. Styles 

 distinct, more or less connected together. Fruit of various 

 shapes. Seeds enveloped in wool or pulp, some of them are 

 without albumen ; these have corrugated or convolute cotyle- 

 dons, but those furnished with albumen have flat cotyledons. 

 This order is very closely allied to Malvaceae, from which per- 

 haps it is not distinct; it agrees with it in the 1-celled anthers, 

 in the petals being usually convolute, and in habit, but differs 

 from it in the calyx being imbricate, not truly valvate, in the 

 staminiferous tube being divided into 5 bundles or sets at the 

 apex, not monadelphous, as in that order. It comes also near 

 to Byttneriaceee and Chlenacece in habit, but it is easily distin- 

 guished from these two orders in the anthers being 1-celled, not 

 2-celled. The species are fine tropical trees and shrubs. Some 

 of them are amongst the largest trees in the world ; Adansdnia 

 digitata, the Baobab of Senegal, or Monkey-bread of the 

 English colonies on the coast of Guinea, has been seen with a
