Description
Newcastelia velutina is an erect shrub growing to 1.5 m tall. The stems are erect, cylindrical, woody and densely clothed with branched woolly hairs. The leaves are decussate, sessile, broadly lanceolate, up to 4 cm long and 1.2 cm wide, recurved along the margin and densely greyish-woolly hairy all over. The leaf midrib is prominent on the undersurface, the lateral veins and reticulation concealed by the dense, branched hairs.
The inflorescence spikes are terminal on branches, elongated, cylindrical, densely woolly hairy, 6 to 17 cm long. The peduncles are up to 3.5 cm long, cylindrical, densely greyish-woolly hairy. The flowers are bracteate and sessile. The calyx is tubular, 5-lobed towards the apex, glandular and densely cottony-woolly outside, glabrous inside. The corolla is campanulate, 5-lobed at the apex, glabrous outside, densely villous hairy inside the tube. The corolla lobes are abruptly narrow linear towards the apex and somewhat broader at the base, glabrous. The corolla tube is more or less cylindrical in the lower half, gradually widening towards the apex. There are five included stamens, inserted in the corolla-throat. The ovary is more or less globose, glandular and hairy in the upper part, glabrous below. The fruit have not seen (Munir, 1978; Stanley, 1986).
Newcastelia velutina is similar to N. cladotricha in having elongated spikes and included stamens and style, but can be easily distinguished by its spikes being uninterrupted, cottony-woolly, not fluffy; flowers 3 in the axil of each bract; calyx glandular and greyish cottony-woolly outside; corolla-lobes (abruptly) narrow linear and ovary glandular and hairy in the upper half, glabrous and non-glandular below.
N. velutina is also related to N. interrupta, however, the leaves in N. interrupta are often three in a whorl below the inflorescence; stem and leaves are non-velutinous; peduncles purplish-grey tomentose; spikes interrupted; corolla-loes narrowly ovate, tube with a dense villous band near the base inside, and ovary hairy but not glandular in the upper half (Munir, 1978; Stanley & Ross, 1986).

Habitat
Newcastelia velutina is found growing amongst granite outcrops and in skeletal soils derived from granite in open shrubland, adjacent to woodland or open forest. Associated canopy species in rocky exposed sites include Corymbia petalophylla, E. exserta, E. dura and Acacia grandifolia. Common species in the shrub layer are Leptospermum neglectum and Acacia eremophiloides. Frequent tree species in less exposed sites of open forest include Eucalyptus apothalassica and Corymbia watsoniana with shrub layer of Leptospermum neglectum, Xanthorrhoea johnsonii, Grevillea whiteana and Acacia spp. (Halford 1993, Queensland Herbarium, 2012).
Reproduction
Newcastelia velutina is known to flower from June to November and has been collected in fruit in November (Queensland Herbarium 2012). Flowers remained open for 4 to 5 days (Halford, 1993). See viability is low with only 42% of embryos tested found to be viable (Halford, 1993).
Threatening processes
No substantiated threatening processes recorded in the literature.
Status notes
Newcastelia velutina is listed as Vulnerable under the Queensland Nature Conservation Act 1992.
