Calyx of 4-5 sepals (f. 90. d. f. 91. .). Sepals connected at 

 the base, imbricate in aestivation (f. 91. .), unequal; the upper 

 one drawn out into a spur (f. 90. d. f. 91. &.). Petals 1- (f. 

 90. b. a.) 2-3 (f. 91. d. c.) or 5, alternating with the calycine 

 lobes, and inserted at their base. Stamens 1 (f. 90. c.) -5, usually 

 opposite the petals, rarely alternating with them, and inserted 

 in the bottom of the calyx, the most of them usually sterile and 

 small, only one fertile and bearing an ovate (4-celled, ex Mar- 

 tins) anther. Ovarium free, or adhering to the calyx, 3-celled 

 (f. 91. h.) ; ovula 1-2, or few in each cell, attached to the base 

 of the axis. Style 1 (f. 90. g. f. 91. g.). Stigma 1. Capsule 

 trigonal (f. 91. h.), 3-celled, 3-valved ; valves opening along 

 their middle. Seeds exalbuminous. Embryo straight, inverted. 

 Cotyledons large, foliaceous, plicate, convolute. Radicle short, 

 superior. South American trees, with opposite tetragonal 

 branches. Leaves opposite or verticillate, but sometimes al- 

 ternate at the tops of the branches, quite entire, feather-nerved, 

 bistipulate at the base. Flowers racemose, panicled or thyrsoid, 

 usually terminal ; pedicels bracteate. 



This order agrees with Gutliferce and Marcgraviaceee in the 

 habit and flowers, but is distinguished from them in the stamens 

 being inserted in the calyx. It agrees with Cotnbretacece in the 

 cotyledons being convolute, and in the inverted seeds ; and with 

 some of the genera of Onagrdrice, especially with Lopezia, in 

 the stamens being solitary from abortion. Perhaps this order 

 comes nearer to Violaricce than to any other, an affinity which is 

 pointed out by the irregular flowers, trilocular ovarium, and sti- 

 pulas ; in fact, in every plant of that order the stamens are also 

 perigynous. 



Synopsis of the genera. 



SECT. I. Ovarium free. Calyx 5-parted* 



1 CALLISTHE'NE. Upper sepal drawn out into a large spur 

 at the base (f. 90. d.}. Petal 1, obcordate (f. 90. I.). Stamen 

 1 (f. 90. c.), without any rudiments of sterile ones. Valves of cap- 

 sule without a dissepiment ; cells 1-2 -seeded (f. 89. c.). 



2 AMPHILOCHIA. Upper sepal drawn out into a short spur at 

 the base. Petal 1, obcordate. Fertile stamen 1, usually with- 

 out any rudiments of sterile ones. Valves of capsule bent in so 

 much as to form dissepiments ; cells 1-2-seeded. 



3 VOCHY'SIA. Upper sepal drawn out into a long spur at 

 the base (f. 91. fr.). Petals 3 (f. 91. d.\ middle one the largest 

 (f. 91. c. i. k.~). Stamens 3, lateral ones sterile. Valves of cap- 

 sule opening in the middle. Seed solitary in the cells, winged. 



4 SALVE'RTIA. Upper lobe of calyx furnished with a spur at 

 the base. Petals 5, upper 2 very narrow. Stamens 3, lateral 



ones sterile. Valves of capsule opening in the middle; cells 2- 

 seeded. 



5 QUA'LEA. Upper sepal furnished with a spur at the base. 

 Petals 1, rarely 2. Stamens 1, rarely 2. Valves of capsule open- 

 ing in the middle. Seeds winged. 



SECT. II. Ovary adnate to the calyx. Calyx ^-parted. 



6 EIU'SMA. One of the lobes of the calyx furnished with a 

 spur at the base. Petal 1. Fertile stamen 1, sterile 4. 



f- Genera doubtful whether they belong to the present order. 



7 LOZA'NIA. Calyx with a ventricose tube, and a 5-parted 

 permanent limb. Petals wanting. Disk quadrangular, filling 

 the bottom of the calyx. Stamen 1, small, inserted under the 

 ovary. Capsule trigonal, 3-celled, 3-valved. Seeds 6. Stigmas 

 3, small, capitate. 



8 AGA'RDHIA. Calyx of 3 sepals. Petals 5, convolute. 

 Stamen 1, bearing a large 2-celled anther. Style 1. Drupe 

 oval, 3-celled, 3-valved. 



9 SCHWEJGGE'RIA. Calyx of 3 sepals. Petals 3, one of 

 which is spurred. Stamen 1. Pistil none. Fruit unknown. 



1. Ovarium free from the calyx. Calyx 5-parted.

 philosopher). Mart. bras. 1. p. 123. D. C. prod. 2. p. 25. 



LIN. SYST. Monandria, Monogynia. Calyx of 5 unequal parts 

 (f. 90. rf.), upper one large, and drawn out into a spur (f. 90. d.). 

 Petal one (f. 90. a. i.), obcordate. Stamen 1 (f. 90. c.), alternat- 

 ing with the petal, without any rudiments of sterile stamens. 

 Anther 4-celled ; cells separating by pairs. Ovary free, 3-cell- 

 ed ; cells containing few ovula. Capsule 3-celled (f. 90. e.), 3- 

 valved ; valves without a dissepiment ; cells 1-2-seeded. Seeds 

 adnate to the angles of the' central, thick, trigonal placenta. 

 Resinous trees ; with minute axillary buds, covered with white 

 grains. Leaves and branches opposite and distich, coetaneous, sti- 

 pulate, deciduous. Flowers axillary and lateral. Petals yellowish. 



1 C. MA'JOR (Mart. 1. c. t. 75.) FIG. 90. " 

 glabrous ; leaves elliptic or 



ovate-oblong, obtuse or acute ; 

 flowers solitary in the axils of 

 the leaves, and therefore oppo- 

 site, fj . S. Native of Brazil, in 

 hot sandy places. Petals yellow, 

 lined with scarlet, (f. 90.) 



Larger Callisthene. Tree 10 

 to 12 feet. 



2 C. MINOR (Mart. 1. c. t. 76.) 

 pubescent ; leaves linear-oblong, 

 obtuse, ending in a glandular 

 mucrone ; flowers solitary in the 

 axils, and therefore opposite. ^ 

 S. Native of Brazil, in the high 

 plains called Chepada de Pa- 

 rana. Petals cream-coloured. 



Smaller Callisthene. Tree 15 to 26 feet. 



3 C. FASCICULA'TA (Mart. 1. c. p. 126.) leaves ovate-oblong, 

 obtuse, rather emarginate, glabrous above, and villous beneath ; 

 flowers axillary, in fascicles. Ij . S. Native of Brazil, in the 

 desert between Serra de St. Antonio, and the river St. Fran- 

 cisco, in the province of Minas Geraes. Petals cream-coloured.
