VIII.— POLY G ALIN M. 
Calyx in praeflorescence valvate or imbricate. Corolla in bud induplicate or im¬ 
bricate. Stamens definite. Anthers usually opening by a terminal pore. Ovary two- 
celled, generally with 1 or 2 ovules in each cell. Placentation axil. Embryo straight, 
often surrounded by albumen. 
Order TBEMANDBEiE. 
H. Br . in Flind. Voyage, ii. 544. 
Plowers bisexual, symmetrical. Sepals 4-5, free or at the base connate, valvate 
in (estivation. Petals 4-5, free , induplicate in bud, deciduous. Stamens 8-10, free, 
hypogynous, all fertile. Eilaments short. Anthers connivent, extrorse, 2-4-celled, 
opening by a terminal pore. Pollen-grains smooth. Ovary hoo-celled, compressed. 
Ovules 1-3 in each cell, pendulous. Styles 2, perfectly connate, rarely free towards 
the summit. Stigmas minute, confluent. Capsule two-celled, compressed, bursting 
by loculicidal dehiscence. Seeds pendent. Hilum naked. Chalaza terminal. Embryo 
straight, cylindrical, placed in the axis of fleshy albumen. Itadicle superior. 
Shrubby or suffruticose ornamental often heath-like plants, restricted to extra- 
tropical Australia and Tasmania. Leaves alternate or verticillate, rarely opposite, 
simple, entire or toothed, sessile or short-stalked, sometimes reduced to min ute scales. 
Stipules wanting. Pedicels axillary, often solitary. Petals purplish, rarely white —

It oh. Brown indicated to Tremandreae a position in the series of natural orders 
next to Polygaleae. Steetz in his masterly dissertation placed them lucidly next 
to the lasiopetaleous tribe of Buettneriaceae, from whence they establish a link to 
Poly galeae. Simultaneous to the issue of Dr. Steetz’ memoir the Tremandrese were 
placed next to Buettneriaceae by the author of this work (conf. P. M. Eirst Gen. 
Deport on the Vegetation of Victoria, p. 10). To retain them in that position would 
perhaps be most advisable. 
Some alliance of this order to Pittosporeae also exists, as noted by Professor 
Bindley. The habit of Dhytidosporum procumbens is not unlike that of some Tetra- 
thecae and its capsule is by no means dissimilar to that of Platytheca galioides, although 
considerable embryonic differences between the seeds of both exist. External resem-
