2. S. Bartlingii (after C. Bartling), J//(/. Fl. Ind. Bat. ii. 133. A tree, 

 the branchlets pubescent and more or less compressed. Leaves ovate-oordate, 

 7in. long, 5in. broad, on petioles of about 7 or 8 lines, or leaves on other trees 

 oblong-lanceolate, and about Sin. long, 2in. broad, on petioles ^ to fin., the 

 nerves on the upper side hairy, otherwise glabrous, the under side velvety. 

 Stipules oblong, about fin. long, velvety outside. Flowers and fruits in dense 

 globular heads above lin. diameter, like S. cordatus, Miq., except perhaps the 

 corolla-tubes longer. 



Hab.: This tree is met with in the tropical scrubs, but not so frequently as S. cordatus. There 

 can be no doubt as to there being two species of this geuus in Queensland, and as Mr. Bentham, 

 Fl. Austr. iii. 402, considered it probable that the pubescent one might be S. Bartlingii, Mig., 

 it is given under that name here. 



2. NAUCLEA, Linn. 



(From the boat-shaped fruits.) 



Flowers crowded in globose peduncle, bracteate, solitary or subpanioled heads. 

 Calyx-tube turbinate or obconic ; lobes 5, usually tipped with valvate processes. 

 Corolla elongate-funnel-shaped, throat glabrous ; lobes short imbricate. Stamens 

 5, oh the throat of the corolla, filaments none or short or long. Ovary 2-celled ; 

 style filiform, stigma capitate, cylindric or submitriform ; ovules many pendulous 

 on adnate ascending placentas. Fruit of 2 dehiscent many-seeded cocci. Seeds 

 imbricate, testa winged ; embryo clavate in fleshy albumen. — Trees or shrubs. 

 Leaves usually large, sessile or petiolated ; stipules large, caducous or sub- 

 persistent. — Hook., Fl. Brit. Inst. iii. 26. 



An Asiatic and Polynesian genus. 



1. N. Gordoniana (after P. R. Gordon, Chief Inspector of Stock), Bail. 

 Bot. Bull. X. An erect tree of about 40ft., with a rather thin, scaly bark. 

 Leaves elliptic -lanceolate, obtusely acuminate, 4 or 5in. long, and from IJ to 2in. 

 broad at the centre, tapering to a petiole of from J to ^in., the primary veins 

 few and distant, very oblique ; the pair of leaves or bracts below the peduncles 

 narrow-lanceolate, 1 to IJin. long, and shortly petiolate. Flower-heads solitary 

 or 3 at the end of the branchlets, globose, and when in flower scarcely attaining 

 lin. in diameter, on peduncles of about lin. Flowers glabrous. Calyx with 

 very hairy, short, acute lobes. Corolla-tube slender in the lower half, then 

 expanding upwards, lobes short, acute. Stamens 5, the filaments scarcely half 

 as long as the anthers, style glabrous, exserted, stigma capitate. No ripe fruit 

 to hand. ' 



Hab.: Barron Biver, E. 



This tree is certainly in some respects related to our Leiehhardt Tree, of which there are 

 probably more than one species ; it is, however, of more slender habit, and the inflorescence I 

 consider to agree better with the genus Nauclea, in which I place it, than with Sarcocephalus, 

 the genus to which the common Leiehhardt Tree belongs. 



Wood of a light-yellow colour, close-grained, and firm ; useful for studs and lining-boards. — 

 Bailey's Cat. Ql. Woods No. 238a. 



3. UN car: A, Schreb. 



(Named from the hooks formed by the old peduncles.) 



Calyx-tube spindle-shaped ; limb 5-lobed or parted. Corolla-tube long funnel- 

 shaped; limb 5-lobed, valvate ; throat glabrous. Stamens 5, attached on the 

 throat of the corolla ; filaments short ; anthers with 2 basal bristles. Ovary 

 2-celled ; style slender ; stigma capitate ; ovules many, ascending on projecting 

 placentas. Capsule elongate, septicidally 2-valved, many-seeded. Seed imbricat- 

 ing upwards, testas winged above and below ; embryo clavate, in fleshy albumen.
