Botanical Name

Callerya sp. Beatrice Creek (L.S.Smith 10487)

() : . Type: ?.


Vine stem diameters to 16 cm recorded. Stem bark layer quite thick, more than 1 cm on stems about 15 cm diam. Pith produces a small amount of red exudate.


Leaflets about 7-9 per compound leaf. Leaflet blades about 6.5-16 x 2.5-7 cm, leaflet stalks about 5-18 mm long. Lateral veins about 10-14 on each side of the midrib. Stipules thick and fleshy, about 2-3 mm long but often difficult to see. Underside of the leaflet blade much paler than the upper surface, the underside being densely clothed in small, prostrate, almost microscopic hairs. Young shoots densely clothed in pale brown to golden hairs.


Inflorescence a raceme or a raceme of fascicles. Calyx cup-shaped, pubescent on the outer surface, the calyx lobes very small and scarcely visible. Petals: standard broad, about 7 x 10 mm, cleft at the apex, greenish towards the base and densely pubescent on the outer surface; wings about 5-6 x 2-2.5 mm, clawed, (stalked) at the base; keel about 3-3.5 mm long, fused for most of its length. Stamens 10., the filaments of nine stamens fused to form a tube open on one side. One stamen free. Style densely clothed in prostrate golden brown hairs. Ovules one or two.


Fruits about 8-9 x 4-7 cm, bluntly beaked at the apex, constricted between the seeds, surface brown and scurfy. Seeds +/- globular, about 5-6 cm diam. Radicle lateral, small compared with the dimensions of the cotyledons.


Cataphylls, 1 or 2, produced before the first true leaves. First true leaf bifoliolate, compound leaf axis extending beyond the leaflets as a linear structure about 3 mm long. Second leaf trifoliolate, leaflets elliptic. At the tenth leaf stage: leaf pinnate with about 7 leaflets, leaflet blades elliptic, apex acuminate, base cuneate to obtuse. Lateral veins about 9-11 on each side of the midrib and forming loops inside the blade margin. Stalk of the terminal leaflet longer than those of the lateral leaflets. Lower leaflet surface, compound leaf rhachis, leaflet stalks and stem densely clothed in brown appressed hairs. Stipules triangular, about 2 mm long, densely clothed in brown hairs.
