<:elled ; placentas turgid ; seeds rhomboid-or clavate-ovate, pale- 

 brownish, shining, reticulated.

This first and perhaps only Australian species bears some 

 resemblance to A. Vitiensis ; but the leaves are usually broader 

 and more prominently veined, the corolla is less dilated towards 

 the upper end and its lobes are considerably smaller, while 

 the anthers are less curved at the base and open with longer 

 slits. Our new plant shows also some affinity to the Himalaian 

 A. setigera, but recedes firom this as well as most othercon- 

 geners already in the lobeless calyx ; as regards this par- 

 ticular characteristic the Australian plant approaches A. 

 Forbesii, but that Papuan species is essentially different in its 

 nearly semi-globular calyx, longer-lobed corolla, stamens of 

 ■quite other shape and fruits broader than long. The genus 

 Pentapterygium is only sectionally separable from Agapetes and 

 indeed Vaccinium. Our lovely and exceedingly local species 

 (now brought under notice) of a genus of plants, scarcely dis- 

 tinct from that, which comprises the British Bilberry the 

 Whortleberry and the Cranberry-plants (Vaccinium), has been 

 named in honour of Dr. G. A. Mein, who professionally has 

 evinced through many years a keen interest in the writer's 

 researches. 



DiDYMOCARPUS KiNNEARII. 



Stemless ; leaves lanceolar or cordate-ovate, almost mem- 

 branous, conspicuously serrated, above conspersed with septate 

 hair, beneath as well as the long petioles more silky-hairy ; 

 pe 'uncles reaching generally to the height of the leaves, as well 

 as the many-flowered cyme spreadingly soft-hairy ; flowers small, 

 on elongated almost capillary often umbellate pedicels ; bracts 

 narrow ; calyx about half as long as the corolla, its segments 

 broad-linear, narrowed upwards ; corolla white, glabrous, its 

 upper lobes deeply divided, the middle one of the lower lobes 

 somewhat longer than the others ; tube comparatively ample, 

 not quite as long as the lobes ; stamens two, as well as the style 

 and ovary glabrous ; fruit hardly three times as long as the 

 calyx, about twice as long as the style, narrow ellipsoid- 

 cylindrical, attenuated towards the summit, not stipitate ; 

 placentas amply intruding ; seeds almost spindle-shaped. 



At and near the summit of Mount Bellenden Ker ; Sayer and 

 Davidson. 



This species is in some respects allied to D. cordatus, but the 

 vestiture is whitish, the leaves are all radical and long-stalked 

 the calyces very hairy, the corolla is smaller and the fruit much 

 shorter. Our plant has the general aspect of D. macrophyllus. 

 In the shortness of the corolla-tube D. Kinnearii comes near
