ments oblong-linear, with two glands on the inside at the base. Petals 4-5, 
about the length of the calyx: claws coriaceous, tomentose. Stamens about 
20, all fertile, united into a conical tube ; outer ones shorter. Ovarium ovate, 
5, 8, or 10-celled: ovules numerous, in a double row, in each cell. Style 1: 
stigma 5-10-lobed, stellate. Capsule woody, 5-10-celled, 5-10-valved. 
Seeds winged.— Trees. Leaves on long petioles, broadly ovate, cordate, pu- 
bescent or tomentose beneath, serrated. Peduncles axillary, panicled, longer 
than the leaves. 
This is the same genus with Wallichia, DC. (not Roxburgh), but we entertain 
very great doubts as to its being distinct from Eriochlena: indeed our M. quinque- 
locularis has the involucel, although very minute, more allied in shape to that of 
Eriochlena. De Candolle states that the cells of the capsule in Microchlena (his 
simpen: are l-seeded ; we have not seen the fruit, but can scarcely think that so 
many ovules become abortive. He also attributes to it the quaternary arrangement 
of parts of the flower: in our specimen of the same species he describes, we find, the - 
quinary: whence it is probable that the quaternary was an accidental suppression 
of a fifth part of the normal number.

ORDER XXIV.—HUGONIACEJE. rn. 
Calyx without an involucel, persistent, 5-sepaled: sepals distinct, 
acute, unequal; the two exterior lanceolate, densely pubescent on the 
back ; another dimidiate-ovate, the straight side pubescent, the rounded 
side testaceous and shining; the two inner ones roundish ovate and 
suddenly pointed, testaceous and shining except the short pubescent 
point: zestivation imbricated, quincuncial. Petals hypogynous, 5, 
alternate with the sepals, shortly unguiculate: æstivation twisted. 
Stamens hypogynous, 10, all fertile : filaments united at the base into 
an urceolus, free and filiform above: anthers cordate-ovate, erect, 2- 
celled, opening by two longitudinal clefts. Torus slightly elevated, 
supporting the staminal urceolus and the ovary. Ovarium roundish, 
coriaceous, glabrous, 5-celled: ovules 2 in each cell, pendulous, colla- 
teral Styles 5, distinct: stigmas slightly dilated and lobed. Fruit 
(a nuculanivm) with a fleshy epicarp, enclosing 5 distinct, bony, 1- 
seeded carpels. Seeds pendulous. Embryo in the axis of fleshy albu- 
men: cotyledons flat, foliaceous : radicle short, superior, pointing to 
the hilum.—Shrubs. Leaves alternate, or sometimes crowded and op- 
posite near the flowers. Stipules 2, subulate. Peduncles axillary 1- 
flowered, often by abortion transformed into circinnate spines. 
The only genus referable here has been placed b De Candolle with doubt in 
Chlenacez, which we cannot agree; that jeder having the calyx and espe 
in a ternary, while the corolla and andrecium follow the quinary dungen p: 
Kunth hesitatingly places it in Buttneriaceæ and the tribe Dombeyaceæ, rs a he 
ìs no doubt that the affinity is very great; it is now separated n 
tübricate (not valvate) calyx, the ovules pendulous (not 
b € radicle superior (not Inlerlor), rather than invalidate the the habit) of 
G, its insertion. In many points it agrees with the character (but ga Arry 
xalideæ, forming another link between the group of Malvaceous orders, an
