134 Alfred J. Ewart:

peduncles, the flowers sometimes more than three together, the bracts usually somewhat shorter and more pointesd. The leaves shorter (about 1cm. long), and the whole plant covered with a more or less well-developed pubescence, the scabrous hairs less developed.

From O. strigossa, Benth., it differs in its twenty or more ray florets, equal pappus and short nonseptata scabrous hairs. It bears some resemblance to O. adenolasia (F. v. M.), but is distinguished by its more numerous ray florets, larger heads, more pointed and usually coloured bracts.

PHYMATOCARPUS. (Myrtaceae).

The leaves of this plant are given as opposite in Bentham's Flora, as in Beaufortia and Regelia. Examination shows that they are all alternate in Phymatocarpus, though closely set in P. porphyrocephalus, the bases are all at different levels, and in P. Maxwelli the internodes between the separate leaves are of some length. This gives an easy mode of distinguishing roughly Phymatocarpus from Beaufortia and Regelia. The only exception to the rule of opposite leaves in the last two genera is in Beaufortia squarrosa. This has mostly opposite leaves, but in some of the shoots, the leaves, though closely set, are alternate, the bases being at all different levels. This is probably an instance of partial reversion to the more primitive type.

PODOLEPIS SPENCERI, A.J.E (Compositae).

This plant bears a close external resemblance to P. aristata, Benth., Fl. Aust., III., 605, from which, however, the blunt outer bracts, the less deeply lobed ray florets, and the flowers white or pale instead of yellow distinguish it. Mr. Max Koch, its discoverer, also informs me that P. spenceri is only found in damp places near river flats, whereas P. aristata grows in drier situations.

PTEROSTYLIS CONCINNA × P. REFLEXA, var. INTERMEDIA.

A hybrid Orchid.

In all large genera (Salix, Eucalyptus, Acacia, Rubus, Hieracium) the imperfect segregation of certain species may result in the
