orgyalis (D. Sturt.). Calyx 5-partitus, aequalis; sepalis

labiis obtusis, extus pubescens, intus hinc (inferius) barbata. Labium
superius tripartitum; lobo medio bifido (e duobus conflato); laciniis
omnibus obtusis; inferius obcordatum bilobum lobis rotundatis, densius
barbatum. Stamina quatuor didynama, omnino inclusa. Filamenta glabra.
Antherae reniformes, loculis apice confluentibus. Ovarium dense lanatum.
Stylus glaber. Stigma indivisum, apice styli vix crassius.

OBS. M. Alphonse De Candolle, in Prodr. xi. p. 715. refers S. ochroleucus
of Cunningh. MSS. 1817, as a variety to S. maculatus; it is however very
distinct, having a short erect peduncule like that of S. glaber, to which
it is much more nearly related, differing chiefly in its being slightly
pubescent.

23. GREVILLEA (EUGREVILLEA) Sturtii, foliis indivisis (nonnullis raro
bifidis) auguste linearibus elongatis uninerviis: marginibus arcte
revolutis, racemis oblongis cylindraceisve: rachi pedicellis
perianthiisque inexpansis glutinoso-pubescentibus, ovario sessili, stylo
glabro.

DESC. Arbor 15-pedalis (Sturt.) Rami teretes, pube arcte adpressa

glutinosa intermista. Flores aurantiaci.

OBS. In the collection presented to the British Museum by Sir Thomas
Mitchell, of the plants of his last expedition, there is a very perfect
specimen, in flower, of Grevillea Sturtii.

The following observations respecting the Grevilleae of the same
collection may not be without interest.
