Cult. The species of this beautiful genus of little shrubs 
deserve to be cultivated in every green-house, but they are very 
difficult to preserve, as well as extremely difficult to procure, 
as seeds seldom vegetate after a voyage from their places of 
natural growth. They thrive best in a mixture of very sandy 
loam and peat.” Young cuttings will root freely if planted in a 
pot of sand, with a bell-glass placed over them. 
Il. TREMA’NDRA (from TpEuw, tremo, to tremble, to 
shake, and avep avépoc, aner andros, a male; the anthers being 
slightly fixed by their base to the points of the filaments, 
shake from the least motion or breath of air.) R. Brown. ined. 
and D. C. prod. 1. p. 344. 
Lin. syst. Decéndria, Monoginia. Calyx of 5 sepals. Petals 
5. Stamens 10; anthers 2-celled. Shrubs, with the habit of 
Heliinthemun, beset with starry hairs. 
1 T. sterxrcera (R. Br. ined. and D. C. prod. 1. p. 344.) 
erect ; leaves ovate, entire, under surface hoary, upper surface 
beset with rough stellate hairs. h.G. Native on the eastern 
coast of New Holland. Habit of plant like Herménnia or He- 
lianthemum alyssoides. Flowers purple? 
Star-bearing Tremandra. Shrub 1 to 14 foot. 
2 T. pirrv'sa (R. Br. ined. and D. C. prod. 1. p. 344.) dif- 
fuse, much branched ; leaves ovate, with a few deep teeth, upper 
surface glabrous, under surface scabrous from a few scattered 
stellate hairs, 
purple ?

Cult. The species of this genus require the same treatment 
as Tetrathèca. 
Orver XXV. PITTOSPO'REÆ (shrubs agreeing with 
Pittósporum in many important characters.) R. Br. gen. rem. 
ter. austr. p. 10. D. C. prod. 1. p. 345. 
Calyx of 5 deciduous sepals, which are sometimes free, and 
sometimes united together to the middle (f. 73. a.) they are im- 
bricate in the bud. Petals 5, hypogynous, with the claws con- 
niving, sometimes united, with spreading lamina (f. 73. d. c.) 
which are imbricate in the bud. Stamens 5 (f. 73. d.) hypogy- 
nous, distinct, alternating with the petals. Ovary 1, free (f. 73. 
c.) with the cells or placentas 2-5 or many-seeded. Style 1 (f. 
73. f-), crowned by numerous stigmas (f. 73. g.) which are equal 
in number to the placentas or cells of the ovary. Pericarp capsu- 
lar or baccate ; cells many-seeded, sometimes incomplete. Seeds 
usually covered with glutinous pulp. Embryo minute, placed 
near the umbilicus in a fleshy albumen, with a longish radicle 
and short cotyledons. 
This order contains beautiful trees and shrubs, or climbing 
shrubs as Billardiéra, with alternate simple feather-nerved 
leaves, destitute of stipulas, usually entire. Flowers terminal 
or axillary, sometimes polygamous; they are from white to yel- 
low, usually of a bell-shaped form, with a spreading border. 
This order is distinguished from the neighbouring tribes in the 
seeds being enveloped in resinous pulp, and in the imbricate 
æstivation of the petals and sepals. Nothing is known of the 
properties of the plants contained in this order.
