184 DESCRIPTIONS OF NEW SPECIES OF CALLI8TEM0N. By Edwin Cheel. [Read 27th October, 1943.] Callistemon comboynensis, n. sp. Frutex in natura, arbor parva ad 4-5 m. in ciiltura. Folia 5-8 cm. longa, lineari-lanceolata, nervo medio prominente, eis transversis minus conspicuis, intra-marginalibus vix manifestis. Flores in spicis 5-9 cm. longis, flos quisque bractea obtusa, spadice, paleacea, caduca, substriata, plus vel minus molle pubescente, plerumque 6-12 mm. longa, florem juvenilem duplo interdum excedente, subtensus. Calycis tubus viridis, glaber, dentibus perbrevis fuscis. Petala pallidi-viridia, orbicularia, diam. 3 mm., margine leve ciliata. Filamenta 2-4 cm. longa, puniceo-rubra, antheribus purpureo-viridibus. Stylus stamina aequans, stigma globosa. Capsulae triloculares, maturitate ca. 5 mm. diam., ad ores leve contractae. Plant of shrubby habit in nature, forming a small tree up to 4-5 m. in cultivation. Leaves 5-8 cm. long, linear-lanceolate with a prominent central nerve, the lateral trans-verse nerves less prominent. Intra-marginal nerves not visible except with a lens. Flowers in spikes from 5-9 cm. long, the individual flowers supported by obtuse reddish-brown, chaff-like, fugacious bracts, faintly striated and more or less softly pubescent, usually from 6-12 mm. long or about twice as long as the fully developed buds. Calyx-tube green, glabrous, with very short brown lobes. Petals pale-green, rotund with slightly ciliate margin, 3 mm. diam. Filaments 2-4 cm. long, reddish, with a tinge of crimson, anthers tinged purplish-green. Style as long as the stamens with a globose stigma. Capsules 3-celled, about 5 mm. diameter when fully matured, slightly contracted at the orifice. This plant somewhat resembles C. viminalis Cheel, but is more shrubby when in the juvenile stage and less tall when fully developed ; the bark is less corky or papery than that of the two forms of C. viminalis. The leaves of C comhoi/nensis in the juvenile stage are silky-hairy, and magenta or rose-pink, the colour disappearing when fully developed and then almost glabrous. The oil-glands are numerous and emit a fragrant essential oil with an odour somewhat like that of all-spice. The plant also differs from the coastal bottlebrush, C. citrinus (Curt.) Domin (Syn. C. lanceolatus (Sm.) Sweet) in the peculiar habit of the first flush of rose-pink young leaves in spring (August-October) not having flowering spikes. In December the terminal spikes of flowers enclosed in reddish-brown-coloured bracts are produced which, when expanded, develop the infra-terminal young growth of rose-pink-coloured leaves and twigs. The flowering season from December to May has been noted for several years in contrast to that of C citrinus which is usually from September to November. Type: Comboyne Ranges in crevices of rocks. E. Cheel, December, 1926. At first sight this species might easily pass as a form of C citrinus and, indeed, was classified as such by Chisholm (1925). During December, 1926, when visiting Lansdowne, I collected specimens with mature capsules and seeds, from which I was successful in raising seedlings. Two of these in cultivation at Ashfleld and the Botanic Gardens, Sydney, have been kept under close observation with the result that I am now able to furnish the above description. Callistemon hortensis, n. sp. Frutex coartatus, 1-2-6 m. altus, ramulis gracilibus. Germina infraterminalia juvenilia foliaque primum sericeo-tomentosa, roseo-punicea tincta fusca, maturitate paulatim pallescentia in colorem flaviviridem. Folia cum punctis oleiferis multis anguste
