especially uudemeath, Plowers very small, purple, in little cymes or clusters 

 along the peduncle, forming intemipted spikes or racemes of 6 to 10 in. in 

 the males, much shorter in the females. Drupes about 3 lines long. 



N. Australia. Aruhem's Bay, R Brown; Victoria river, F. Mueller. The latter 

 specimen has the leaflets very densely and softly velvety on both sides; in R. Brown's speci- 

 mens they are not more so than in the majority of Indian specimens. {Ilerb, R- Br. and

riowers hermaphrodite. Calyx small, of 4 or 5 distinct sepals. Petals 4 

 or 5, imbricate in the bud. Disk thick. Stamens 8 or 10 ; filaments flattened, 

 densely villous. Ovary of 4 or 5 distinct carpels, connected upwards by a 

 short style ; stigma inconspicuous. Ovules solitary In ^acli cell or accom- 

 panied by a second smaller abortive one. Fruit unknown. — A shrub or tree, 

 pubescent with simple hairs. Leaves alternate, simple, Flowers axillary. 



The genns is limited to a single species, endemic in Anstraha. We had, in our * Genera 

 Plantarum/ placed it doabtfully amongst RataceiS-Boronlecp, with which it is closely con- 

 nected by the flowers, but, on further consideration, the want of glandular dots, the bitter 

 bark, and simple hairs have induced us to remove it to Simarubece, 



1. H. Bidwilli, Ilook.f, in BentL and Hook. Gen. PI 294. Probably 

 a tall erect shrub or tree, the young shoots silky-pubescent with appressed 

 simple hairs. Leaves petiolate, lanceolate, narrowed at each end, but usually 

 obtuse, 3 to 4 in. long, entire, coriaceous, glabrous on both sides, or with a 

 few small appressed hairs on the veins underneath, not dotted. Flowers small, 

 hortly pedicellate, in axillary clusters, with a few appressed strigose hairs on 

 the pedicels and petals. Petals ovate, much imbricate, rather more than 1

 side, with long hairs. Ovary hirsute,

Flowers hermaphrodite. Sepals usually 5, nearly as long as the petals, 

 enlarged and stellately spreading under the fiiiit, imbricate in t^e bud. Petals 

 5, imbricate in the bud. Stamens 10 ; filaments filiform. Disk none. Car- 

 pels 1 or 5, free; styles distinct, inserted on the inner angle above or below 

 the middle ; stigmas dilated or capitellate ; ovules 2 in each carpel, collateral, 

 pendulous or ascending. Fruit-carpels coriaceous, small, indehiscent or ob- 

 scurely 2-valved. Seeds solitary, without albumen; testa membranous; em- 

 l)ryo curved.— A tree. Leaves alternate, simple, with smaU, often deciduous 

 stipules. Flowers in short loose axillary racemes. 



The genus is liny ted to Australia, it only diff'ers from Suriana in the arborescent hahit 

 and thinner spreading calyx.
