AND STERCULIACE X. 103 
*** Styli apice attenuati. Carpella vulgo 5. 
5. P. tasmanicus.—Sida tasmanica, Hook. fil. in Hook. Journ. Bot. 
ii. 412.— P. pulchellus, var. 8, Hook. fil. Fl. Tasm. i. 49.— Tasmania ; 
also Southern Australia, on the rivers Tambo and Buchan, F. Müller. 
6.? P.sp.?— Sida dictyocarpa, Ferd. Müll. MS.— Sida spicata, Backh. 
MS., non Cav.—On the Brisbane River, Fraser, F. Müller ; Kirkton 
on the Upper Hunter River, Backhouse. 
The foliage, indumentum, and inflorescence are those of P. 
sidoides, but the flowers are more crowded and sessile. Calyx 
shorter, broadly campanulate. Carpels usually five, strongly reti- 
culate. A very distinct species; but the specimens are insufficient 
to assign its exact place. 
**** Styli superne subclavati. Carpella oo, matura membranacea, 
tU valde compressa. 
7. P. Lyallii, Hook. fil. MS.—Hoheria Lyallii, Hook. fil. Fl. N. Zel. 
i. 31, t. 11.—N. Zealand. 
This plant appears to me to be much better placed in Plagi- 
anthus than in Hoheria, reducing the latter genus to the single 
H. populnea, which has terminal peltate stigmas and remarkably 
winged carpels. ' 
Sect. 2, Lawrencra. Calyx 5-angulatus, sepe turbinatus. 
Styli apice attenuati. Carpella 3-5, nonnulla sepe abortientia. 
8. P. spicatus.— Lawrencia spicata, Hook. Ic. Pl. t. 261, 262.— Tas- 
mania and Southern and Western Australia, from Port Fairy to Swan 
River. 
9. P. glomeratus.— Lawrencia glomerata, Hook. Ic. Pl. t. 417.—Swan 
River, Drummond. 
10. P. squamatus.—Lawrencia squamata, Nees, Pl. Preiss. i. 242.— 
Swan River, Preiss ; Drummond, 4th coll. n. 106. 
11. P. microphyllus, F. Müll. Fragm. Phyt. Austr. i. 29.— Victoria, 
F. Müller; Swan River, Drummond, coll. 1845, n. 208, and 4th coll. 
n. 252. 
Srba, Linn. 
Dictyocarpus, Wight, has already been restored to this genus; 
and Fleischeria, Steud. (Steetz in Pl. Preiss. ii. 305), consisting of 
the single Sida calyxhymenia, Gay (DC. Prod. i. 462), only differs 
from other species in the calyx more enlarged, spreading aud mem- 
branous after flowering—a character which appears to us wholly 
insufficient to justify the establishing a monotypic genus.
