186 XXIX. EUTACEiE. [Soroma. 



Leaves mostly 3-foliolate. 

 Common petiole distinct. 

 Leaflets fiat, linear oblong or obovate. Anthers apiculate. Pedioels_ 



1-flowered 9. B. polygaUfolia. 



Leaflets linear-terete, mueronate. Anthers not apiculate. Pedicels 1 



to 3-flowered 11. B.falci/oUa. 



Leaves linear or lanceolate, acute, or the lower ones rarely euneate. 



Low undershrub. Flowers all axillary. Sepals short 9. B. polygaUfolia. 



Series IV. Terminales. — Petals imbricate. Anthers nearly uniform. Leaves all simple 

 {except in B. filifolia, inornata, aiid oxyantha). Flowers mostly or all terminal, sessile or on short 

 1-flowered peduncles. 



Terminal flowers solitary, or rarely 2 or 3, sessile or shortly pedicellate.

 Small undershrub. Filaments nearly glabrous. Anthers not apiculate 12. B. parviflora. 



1. B. artemisisefolia (Artemisia-leaved) F. c. M. Frac/m. i. 66; Benth. Fl. 

 Austr. i. 311. A shrub, clothed all over with a soft, hoary, close or velvety 

 tomentum. Leaves all, or nearly all, pinnate. Leaflets 7 to 11 or more, crowded 

 on a short common petiole, linear, obtuse, rarely exceeding |-in. and often much 

 shorter, the margins closely revolute. Peduncles axillary, solitary, short, 

 1-flowered. Sepals lanceolate, tomentose, valvate, attaining 3 to 4 lines. Petals 

 lanceolate, valvate and tomentose like the sepals, but smaller and enclosed ih 

 them in the bud. Filaments slightly hirsute, clavate and glandular at the top. 

 Anthers scarcely apiculate. Ovary pubescent. Seeds smooth but scarcely 

 shining. 



Hab.: Islands of Gulf of Carpentaria, R. Brown. 



2. B. eriantha (alluding to the woolly flowers), Lindl. in Mitch. Trap. Austr. 

 298 ; Benth. Fl. Austr. i. 813. A glabrous shrub, the branches angular. Leaves 

 pinnate ; leaflets 3 to 9, obovate or oblong-cuneate, obtuse or with a recurved 

 point, rarely above 3 lines long, rather thick, arid often folded upwards length- 

 wise, the margins never recurved. Peduncles axillary, short, 1 or rarely 

 2-flowered. Sepals ovate, acute, glabrous outside, minutely tomentose inside. 

 Petals more than twice as long, attaining 3 or 4 lines, rather narrow, valvate, 

 hoary-tomentose outside, with a prominent midrib. Filaments usually* ciliate ; 

 anthers apiculate. 



Hab.: Near Mt. Pluto, Mitchell. 



With the aspect of B. microphylla this has the floral characters of B. ledifolia, with which 

 F. V. Mueller proposes to unite it, but besides a totally difierent habit, the leaflets are thick, 

 equally green on both sides, with the margins flat or folded upwards, not recurved with a pale or 

 hoary-tomentose under surface as in B. ledifolia. — Benth. 



3. B. alulata (small- winged), Soland. in Herb. Banks ; Benth. Fl. Austr. i. 

 313. Apparently a divaricate or diffuse shrub, the young branches glandular- 

 tomentose. Leaves pinnate ; leaflets 7 to 13 or even more, oblong or linear, 

 rarely almost ovate, obtuse, 2 to 8 lines long, the margins revolute, glabrous 

 above when full-grown, hoary-tomentose underneath. Peduncles very short, 

 axillary, 1-flowered. Sepals lanceolate, subulate-acuminate, from half to nearly as 

 long as the petals. Petals about 3 lines long, mueronate, valvate in the bud but 

 rather broad, glabrous outside with a prominent midrib, slightly tomentose 

 inside. Filaments clavate and glandular upwards.

4. B. ledifolia (Ledum-leaved), J. Gai/ : DC. Prod. i. 722 ; Benth. Fl. 

 Austr. i. 314. An erect shrub, the young branches glandular-tomentose. Leaves 

 simple, 3-foliolate, or rarely pinnately 5 or even 7-foliolate ; leaflets linear, 

 oblong-linear, lanceolate or rarely broadly oblong, when single oCtpii above liu. 

 long, when several rarely above Hn., the margins recurved or revolute, glabrous
