rejects it in his Mantissa, p. 332, as pointed out in DC. Prod. iii. 59. Although, therefore, 
Linnaeus may have confounded this plant with some other, it is certainly not the one he had in 
view in characterising his L. perennis, and Arnott and others are fully justified in adopting 
Roxburgh’s L. parviflora. As to L. diffusa, Hamilt., although he also thought Rheede’s Caramba 
might be the same, it is in fact quite distinct in the long slender ovary and capsule, and in some 
measure in inflorescence. It is L. prostrata, Roxb. FI. Ind. i. 420 ; Wight, Ic. t. 7G2, and 
includes the three species of Nematopyxis, described by Miquel FI. Ind. Bat. i. part i. 630. It 
has not yet been found in Australia. — Bcntli. 
Order LV. SAMYDACE.E. 
Sepals free or united at the base into a 4 or 5-lobed (rarely 2, 3 or 6 or more 
lobed) calyx, free from the ovary or more or less adherent. Petals either as many 
as the sepals or calyx-lobes, inserted at their base, persistent with them, and 
resembling them in consistence, or wanting. Stamens perigynous, indefinite or 
not corresponding in number with the calyx-lobes, or, if equal to them, usually 
opposite the petals and alternating with small glands or scales. Ovary superior 
or more or less inferior, with 2, 3 or more parietal placentas and several ovules to 
each placenta ; style entire or more or less divided into as many branches as 
placentas. Fruit indehiscent or opening in valves between the placentas. Seeds 
often arillate, with a fleshy albumen. Embryo straight or nearly so, with the 
radicle next the hilum and flat cotyledons. — Trees or shrubs. Leaves alternate, 
undivided, usually toothed. Stipules small or none. Flowers hermaphrodite or 
rarely dioecious. 
A considerable Order, if taken with the limits above given, and widely distributed over the 
New and the Old World, chiefly within the tropics. 
Tribe I. Casearieae. —Leaves alternate. Calyx 4 to 5-merous. Petals none. Stamens 6 
to 15, springing from the margin of the flower-tube in a single row. Staminodes equal in number 
to the fertile stamens, and alternating with them. 
Stamens 6 to 15, combined into a tube below. Style simple, 3-lobed or entire at 
the apex. Flowers tufted 1. Casearia. 
Tribe II. Komalieae . — Leaves alternate. Flower-tube free or more or less adnate to the 
ovary. Sepals and petals 4 to 15, distinct. Stamens equal in number to the petals, opposite to 
them, or more numerous and collected in tufts in front of them, alternating with glands placed 
opposite to the sepals. 
Ovary more or less adherent. Petals flat, as many as sepals 2. Homalium. 
1. CASEARIA, Linn. 
(After J. Casearius.) 
Calyx-lobes 4 or 5. Petals none. Stamens 6 to 15 or rarely more, alternating 
with as many short ciliate or hairy scales (staminodia ?), all in a single series and 
united in -a perigynous ring at the base. Ovary superior, 1-celled, with 3 or rarely 
4 parietal placentas ; style entire or shortly 3-lobed. Fruit somewhat succulent, 
opening in valves or more fleshy and indehiscent. Seeds often with an arillus. — 
Trees or shrubs. Leaves usually, but not always dotted with a mixture of round 
and oblong transparent dots. Stipules lateral. Flowers usually small in axillary 
clusters. 
A considerable genus, chiefly American, with a few African and Asiatic species. 
Leaves not dotted. Stamens 8 C. csculenta. 
Leaves pellucid-dotted. Stamens 10 to 12 2. C. Dallachii. 
1. C. esculenta (used for food), Roxb. FI. Ind. ii. 422; Benth. FI. Austr. 
iii. 309. A large shrub, usually quite glabrous, the branches not angular. 
Leaves from oval-elliptical to nearly oblong, acuminate, narrowed at the base, 2 
to 4in. long or sometimes rather more, scarcely coriaceous, but not dotted. 
Flowers very small, in axillary clusters, the pedicels about 1 line long. Calyx
