C. AMARANTACEiE. 
[Trichinium. 
14. T. calostachyum (spikes beautiful), F. v. M. in Bentli. FI. Anstr. v. 
236. An erect slender slightly branched annual of 1 to 2ft. Leaves few, very 
narrow-linear, almost filiform, the lower ones 1 to 2in. long, the upper ones 
small and distant. Spikes on slender peduncles, at first conical, at length oblong- 
cylindrical, 1 to 14in. long. Bracts and bracteoles ovate, mucronate, very thin 
and shining, 1| to 2 lines long. Perianth pink, 2^ to 3 lines long, the segments 
free from the base, scarious, densely plumose outside with fine hairs short in the 
lower part, longer in the upper half, with shortly glabrous obtuse tips, the 3 inner 
ones rather shorter, with woolly hairs inside towards the base but on the seg- 
ments and not on the staminal cup. Filaments slightly unequal, all bearing 
anthers, united in a short cup with linear or lanceolate exceedingly thin scales 
between them fringed or glandular on the margin. Ovary glabrous. —

calostachyum, F. v. M. Fragm. vi. 231. 
Hab.: Islands of the Gulf of Carpentaria, B. Brown. 
The habit approaches that of some of the annual Ptiloti, the scales between the stamens are 
somewhat variable but present in all the flowers examined, usually about J line long, the other 
characters are entirely those of Trichinium. 
15. T. aervoides (rErva-like) F. v. M. Fragm. iii. 123 ; Bentli. FI. Austr. 
v. 240. Probably perennial and procumbent. Stems branching, the young 
shoots and peduncles clothed with white woolly hairs. Leaves ovate or ovate- 
lanceolate, acute, contracted into a rather long petiole, ^ to lin. long. Spikes 
numerous, solitary or 2 or 3 together on short axillary or terminal peduncles, 
ovoid or conical (or at length cylindrical ?), 3 to 4 lines diameter. Bracts ovate, 
acute, with brown tips, the bracteoles more transparent broader and more obtuse, 
all about as long as the perianth and usually bearing dorsal hairs at the base. 
Perianth scarcely 2 lines long, the segments free from the base, rigid, acute, 
plumose outside with short glabrous tips, glabrous inside. Filaments unequal, 
united at the base in a short glabrous truncate cup, 1,2 or 3 of them without 
anthers. Ovary densely villous on the top. — Ptilotus arvoides, F. v. M. Fragm. 
vi. 231.

6. CYATHULA, Lour. 
(A little cup). 
Sepals 5, scarious, 1-nerved, acuminate or with hooked rigid awns. Stamens 
5, connate, united below with the linear lacerate or 2-fid staminodes into a cup, 
anthers 2-celled. Ovary obovoid ; style filiform, stigma capitellate ; ovule 1, 
pendulous from a long basal funicle. Utricle ovoid, indehiscent, top areolate. 
Seeds inverse, oblong, testa coriaceous ; embryo annular, cotyledons linear, 
flat. — Herbs or undershrubs. Leaves opposite. Flowers clustered, clusters 
solitary, spicate and reflexed in fruit, or in dense, globose, solitary or spicate 
heads ; perfect flowers 1 or 2 in each cluster, surrounded by imperfect ones 
reduced to sepals, with rigid hooked awns. 
The species belong to Asia, Africa, America and Australia. 
1. C. prostrata (prostrate), Blame, Bijd. 549 ; Hook. FI. Brit. hid. iv. 723. 
Stems ascending from straggling almost prostrate branches usually slender and 
from Gin. to 2ft. high, clothed as well as the foliage with close, white, silky hairs. 
Leaves petiolate or nearly sessile, elliptic, rhomboid-oblong, or the lower ones 
subpanduriform and obtuse, 1 to 2in. long. Spikes very slender, terminal, 4 to 6in. 
long, sometimes branched, silky-pubescent. Sepals oblong or somewhat lanceo- 
late. Staminodes 2-fid or retuse. Seeds ovoid-oblong. — C. geniculata, Lour. ;
