OF THE INTERIOR OF WESTERN AUSTRALIA. 219 
ceolatis basi in petiolum attenuatis apice spinuloso-apiculatis 
piloso-puberulis vel vix glabris, spicis abbreviatis late ovoideis 
paucifloris, bracteis bracteolisque rotundato-ovatis breviter spinu- 
loso-acuminatis tenuiter scariosis, perianthii straminei segmentis 
fere omnino liberis extra deorsum piloso-hirsutulis intus glabris, 
antheris minutis, ovario glabro. 
Hab. Ad Gibraltar florebat mens. Sept. 
Nec ultra 5:0 em. alt., plerumque vero humilior. Radix sim- 
plex, tenuis. Folia pleraque 0'5-1:0 em. long., 005-0-2 em. lat., 
radicalia plerumque paullo majora, omnia in sieco lete virides- 
centia. Spies breviter pedunculate, circa 0:7 em. long. et diam., 
4-8-flore.  Bracteole vix 0:5 em. long., glabre. Perianthii 
segmenta oblonga, breviter acuminata, vix carinata, medio viridia 
ibique tantum pilifera, 0:7 cm. long., omnia piloso-hirsutula, 
sursum glabra. Filamenta complanata, basi nuda. ^ Ovarium 
depresse spheroideum, paullo ultra 0-1 em. long. et diam. Stylus 
excentricus, quam ovarium 2plo longior, glaber. Stigmatis 
margo laceratus. 
For a time I thought this might be a very greatly reduced form 
of Trichinium corymbosum, Gaudich., which, apart from the small 
size, i$ resembles superficially to a remarkable extent. On close 
examination, however, some well-pronounced differences come to 
light. Thus all the perianth-segments are hairy on the back, not 
the three outer ones alone, as is the case with T. corymbosum, 
which latter has anthers from four to ten times the size of those 
of T. eremita and longer filaments ; its style also is much longer 
and the edge of the stigma entire, not lacerate. Moreover, 
though the ovary of T. corymbosum is said by Bentham to be 
glabrous, I find a fringe of long hairs attached near the top. 
The ovule also of T. corymbosum is quite different, being only 
half the relative width and oblong in sbape, instead of broadly 
renif rm; and this, if it be a constant character, points to a 
difference in the seed. 
TRICHINIUM HELIPTEROIDES, F. Muell. Near Kilkenny soak, 
June. A form with small flower-heads. 
T. DnuwMoNDir Mog. Not infrequently seen in various 
parts of the interior north of Pendinnie soak, where it flowers 
in June. A form with very small heads barely half an inch in 
diameter. An intermediate form was collected by the Elder 
Expedition at various camps in tbe Victoria desert.
