 Martynia. Leaves opposite. Flowers axillary, solitary. Fruit 

 like those of Trapa. 



1 P. MU'REX (Lin. spec. 892.) O- S. Native of the East 

 Indies, Ceylon, Malabar, Coromandel, &c. near the sea. Lam.

 Cucu - Mullu, or Kakii - tali, 

 Rheed. mal. 10. p. 143. t. 72. 

 A pretty large, succulent, 

 branched plant. Root deep 

 orange - coloured, branched. 

 Stem hardly any. Branches 1- 

 2 feet. Leaves obovate, obtuse, 

 regularly toothed, truncate, 

 pretty smooth, 3-nerved, 2-3 

 inches long, and 1-| to 2 inches 

 broad ; petioles glandular. 

 Flowers pretty large, yellow, 

 on short pedicels, erect ; on 

 each side of their insertion is a 

 small, roundish, brown gland. 



Drupe nutant, armed with 4 sharp spines, one on each corner, 

 at the base. The whole plant has an odour of musk. Of the 

 same genus is the Planta Euphrasies affinis, Pluk. t. 373. f. 2. 

 The sterile filament is terminated by an orange-coloured head. 

 This plant, when fresh, has the singular property of rendering 

 water or milk mucilaginous, without altering the taste, or colour, 

 or smell of the liquid. This effect goes off in the course of 8 or 

 12 hours, leaving the liquid in its former state. Butter-milk is 

 often sold in the markets of India ; and in order to make a 

 greater profit on their merchandize, they dilute it with water, 

 and then thicken the whole by turning it round a few times with 

 a few fresli leafy branches, which makes the adulterated butter- 

 milk seem rich, and of the best sort.

ORDER CLX. COBEA'CE^E (this order only contains the 

 genus Cobce'a.') D. Don, in edinb. phil. journ. 1824. vol. 10. 

 p. 3. 



Calyx leafy, 5-cleft, equal (f. 24. a.) Corolla inferior, cam- 

 panulate, regular, 5-lobed (f. 24. i.), imbricate in aestivation. 

 Stamens 5, unequal (f. 24. &.), rising from the base of the corolla ; 

 anthers 2-celled, compressed. Ovarium superior, 3-celled, 

 surrounded by a fleshy, annular, hypogynous disk ; ovula 

 several, ascending. Style simple ; stigma trifid (f. 24. 6.). 

 Fruit capsular, 3-celled, 3-valved; with a septicidal dehiscence; 

 placenta very large, 3-cornered in the axis, its angles touching 

 the line of dehiscence of the pericarpium. Seeds flat, winged, 

 imbricated in a double row ; their integument mucilaginous. 

 Albumen fleshy. Embryo straight. Cotyledons foliaceous ; 

 radicle inferior. Climbing shrubs. Leaves alternate, ab- 

 ruptly pinnate ; the common petiole lengthened into a tendril. 

 Flowers axillary, solitary. This order is readily distinguished 

 from Bignoniacece and Pedalmece, the two foregoing orders, in 

 the flowers being regular and pentandrous, in the presence of 

 albumen to the seeds, &c. ; and from Polemoniacece it is readily 

 distinguished, by habit alone, and by the winged seeds.

LIN. SYST. Pentandria, Monogynia. Character the same as

1 C. SCA'NDENS (Cav. 1. c.) 

 leaflets 3 pairs, elliptic, mucro- 

 nate, marginate, and slightly 

 ciliated : lower pair close to 

 the stem, and sub-auriculate on 

 one side at the base; tendrils 

 branched ; calycine segments 

 broad, roundish, mucronulate ; 

 stamens about equal in length, 

 hardly longer than the corolla. 



|j . ^. G. Native of Mexico, 

 in various parts. Sims, bot. 

 mag. 851. Calyx glaucous, 

 5-winged, before expansion. 

 Flowers large, campanulate, 

 with a short tube of a dark, 

 dirty purple colour, (fig. 24. 

 Lobes of corolla rather spreading, broad, short, roundish, im- 

 bricate, ciliated. 



Climbing Cobaea. Fl. May, Oct. Clt. 1792. Shrub cl. 



2 C. LU'TEA (D. Don, in edinb. phil. jour. vol. 10. p. 4.) 

 leaflets 3 pairs, oblong-lanceolate, acute ; lower pair close to the 

 stem ; tendrils branched at top ; calycine segments lanceolate, 

 tapering to the apex ; stamens twice the length of the corolla. 

 Tj . w . G. Native of Guayaquil. Flowers yellowish, about 

 half the size of those of C. scdndens. 



Yelloni-fiov/ered Cobaea. Shrub cl. 



Cult. The C. scandens is a great favourite with most gar- 

 deners ; it is a quick-growing, and profuse-flowering climber. 

 It is well adapted for a large conservatory or greenhouse. It 

 grows also well in the open air, in summer, trained against a 

 south wall, or against a house, where it will flower in abundance. 

 The plant is best raised from seeds, which ripen in abundance ; 

 but it may also be raised from cuttings, which latter mode is 

 almost needless. 



ORDER CLXI. ARAGOA'CE^E (this order only contains 

 the genus Aragba.') Genera Bignoniaceis affinis. H. B. et 

 Kunth, nov. gen. amer. 3. p. 154. 



Calyx deeply 5-parted (f. 25. a.) Corolla tubular, salver- 

 shaped (f. 25. 6.) ; limb 4-parted ; the lobes convolutely imbri- 

 cate in aestivation ; at length spreading. Stamens 4 (f. 25. c.), 

 inserted in the sinuses between the lobes of the corolla, exserted ; 

 anthers cordate (f. 25. c.), the cells confluent, opening by a con- 

 tinuous line. Style filiform (f. 25. e.) ; stigrna capitate, minutely 

 papillose. Capsule 2-celled, 2-valved (f. 25. g 1 .); valves cloven ; 

 dissepiment parallel with the valves. Seeds 4-5 in each cell, 

 compressed, with a membranous border. Albumen copious, 

 fleshy. Embryo erect; with plano-convex, obtuse, fleshy, coty- 

 ledons, furnished with 3 nerves ; and a blunt radicle, much 

 shorter than the cotyledons. Much branched shrubs, natives of 

 the mountains, near the city of Santa Fe de Bogota, in New 

 Granada ; with opposite branches. Leaves small, coriaceous, 

 imbricated in 8 rows. Flowers axillary, solitary, nearly sessile, 

 small, white.
