in if. monfaha. Plo\rer3 in pairs, sessile at the end of axillary peduncles, 

 ratlicr shorter than the leaves. Calyx silky-wliite, scarcely 4 lines long at the 

 time of Qoweriug^ with the orbicular bracteoles about half as long, enlarged 

 after flowering to 6 or 7 lines, with the bracteoles reticulate, almost scarious, 

 and quite as long as the calyx, or even exceeding it. Petals ovate, exceeding 

 the calyx-lobes by about 1 line. Stamens rather longer.

3, M. Leichhardtii, F. MnelL Fragm. iii. 91. Apparently more 

 branched and not so rigid as the other two species. Leaves less crowded, all 

 opposite, obovate, very obtuse, mostly | to f in. long, narrowed into a pe- 

 tiole of 1 to 2 lines, softly silky-toinentose on both sides, but not so white as 

 in the other species, and 'becoining nearly ghibrous above with age. Pedun- 

 cles shorter th^n tlie leaves, bearing at the end 3 pedicellate flowers, of whicjx 

 I have only seen tlie calyx, enlarged after flowering to from 4 to 6 lines, with 

 the adnate bracteoles nearlv as long.

Calyx-tube adiiate to the ovary, or none in male flowers ; Vimh 4-- to 7 -cleft. 

 Petals none. Stamens 4 to 6, alternating with as many club-shaped stami- 

 nodia, or fewer or none in the female flowers. Ovary interior, with 1 pendu- 

 lous ovule and a sessile sti-^'ma, abortive in the male flowers. Drupe dry, 

 crowtied by 2 much elongated, erect, spatliulate, wing-hke calyx-lobes, beed 

 oblong, pendulous, without albumen; cotyledons petiolate. convolute round 

 the radicle.— Tall tree. Leaves alternate, broad, entire or lobed. J* lowers 

 polygamous, very small, crowded in dense corymbose cymes. 



The genus consists of a single species common to the tropical regions of Central America 

 and tropical Asia. It forms one of the small group of GyrocarpecB, Dumort., or ^^^//J' 

 lilume, assoeiatcJ by many botanists with La.rinecB, chiefly on account of the ^e ''^oence ° 

 the anthers, but which LinJley is uo doubt more correct ,n ad^'ng as <! f'^^"^ '^«' ^o M^

 and Combrclacea ou the one hand and Hamamehdea ou the other.
