PLUMBAGO Linnaeus 
PLUMBAGO ZEYLANICA Linn. Sp. PL (1753) 151. 
Boeton, Baoebaoe, Rel. Robins. 2b92, July 13, 1913. 
Widely distributed in the tropics of the Old World.

SIDEROXYLON Linnaeus 
SIDEROXYLON sp. aff. attenuatum A. DC. 
Amboina, Wae, Rel. Robins. 1817, November 26, 1913, along the sea- 
shore, locally known as bung a tanjong. 
This is possibly included in the description of Lignum eurinum Rumph. 
Herb. Amb. 3: 63, t. 35, but is not the form figured by Rumphius. In 
Lignum eurinum the leaves are acuminate to acute, but in the specimen 
cited above they are obovate, the apex broadly rounded. It is probably 
specifically distinct from Sideroxylon attenuatum A. DC., but unfortunately 
the flowers are very immature.

A small tree attaining a height of 10 m and a diameter of 12 
cm. Branches reddish-brown, glabrous, the branchlets rather 
densely subcinereous-pubescent with short hairs. Leaves oblong, 
firmly chartaceous to subcoriaceous, 9 to 23 cm long, 4 to 7 cm 
wide, apex shortly, broadly, and obtusely acuminate, base cor- 
date, rarely merely rounded, the upper surface quite glabrous, 
dark-brown or somewhat olivaceous-brown when dry, shining, 
the lower surface a little paler, pubescent on the midrib, often 
also sparingly pubescent on the nerves; lateral nerves about 
13 on each side of the midrib, prominent, anastomosing, the 
reticulations lax ; petioles about 5 mm long, pubescent, ultimately 
nearly glabrous. Cymes axillary and in the axils of fallen leaves, 
staminate and pistillate ones on the same plant, or sometimes
