Stipules soon caducous, triangular, 3.7–7.5 mm long, with a thickened blackish-brown central portion and with paler, somewhat hyaline margins but these often infolded in dry material, glabrous externally, with long pale hairs internally. Leaves clustered towards ends of main and widely divergent lateral branches, ± immature at flowering, subsessile or on puberulent petiole to 7 mm long; blade of mature leaves obovate or obovate-elliptic, 9–17.5 × 5.8–10.5 cm (l/w ratio 1.55–1.9: 1), base cuneate to somewhat attenuate or some leaves abruptly obtuse at base, apex shortly acuminate or (sub)attenuate, lateral veins 7–11 per side, these and the midrib prominent and often pale beneath, surfaces pubescent with hairs densest and longest on veins beneath and midrib above, conspicuous when young, becoming more sparsely hairy with maturity, the blade then scabridulous; minute pocketdomatia present in axils of lateral veins beneath but inconspicuous. Inflorescences terminating leafless lateral branches 11–28.5 cm long, flowers 20 or more, sessile, crowded in capitate corymbs with highly reduced and thickened branches; bracts subtending the main inflorescence branches maroon at least at apex, triangular with a slender apiculum, 3.2–4.5 × 3–4 mm, those subtending the flower clusters smaller, 1–2.5 mm long. Calyx tube (hypanthium) 1.9–2.7 mm long; calyx lobes pink- to maroon-tinged, rounded to broadly and convexly triangular, ± 1 mm long, with an irregular, sometimes toothed margin, glabrous or margins sparsely ciliate. Corolla white except for yellowish-green tube and central portion of lobes externally, glabrous externally; tube narrowly cylindrical, (30–)38–42 × 1.5–2 mm, pilose with long wispy hairs internally mainly in distal half; lobes oblong-elliptic, 5–9 × 3.7–4.2 mm. Stamens with anthers subsessile, held at corolla mouth, 2.6–3 mm long. Ovary bilocular, placentae affixed centrally on septum; style and stigma together 17–19 mm long, glabrous, stigma ± linear, included within corolla tube. Fruit pale green, globose-obovoid, 6–8 mm in diameter, endocarp thin, glabrous, calyx persistent, usually 6–8 seeds per fruit (as few as 2 seeds per fruit reported by Degreef 2006); seeds orange-brown, 4–5 mm in diameter, hemispheric with a slightly angular lower side and a deep circular hilar excavation ca 1.5 mm in diameter, testa smooth and glossy.</p><p>Distribution and habitat</p><p>Restricted to the proposed Rovuma CoE, known from the Rondo Plateau of Southeast Tanzania and the Mueda Plateau and Namacubi Forest (Quiterajo) in northeast Mozambique (Fig. 3). Occurs in deciduous and semi-evergreen coastal and lowland dry forest and thicket on sandy soils, including areas of secondary woodland/thicket, at 90–760 m altitude. At Quiterajo, it was recorded from Guibourtia schliebenii (Harms) J.Léonard dominated dry forest with species of Memecylon L., Warneckea Gilg and Strynchnos L. common in the understorey (J.E. &amp; S.M. Burrows 10748). The type specimen from the same site was found growing in close proximity to a number of rare and globally threatened species, i.e., Xylopia tenuipetala D.M.Johnson &amp; Goyder (Q. Luke 13884), Vismianthus punctatus Mildbr. (Q. Luke 13885), Vismia pauciflora Milne-Redh. (Q. Luke 13886A) and Warneckea cordiformis R.D.Stone (Q. Luke 13887). On the Rondo Plateau, it was noted from within forest of Milicia excelsa (Welw.) C.C.Berg, Dialium L., Albizia Durazz., and Pteleopsis Engl. (= Terminalia L. according to some authorities).</p><p>Conservation status</p><p>This species is known from three locations and has an extent of occurrence of 6601 km 2 and a calculated area of occupancy of 16 km 2. At Mueda Plateau, there has been an estimated loss of dense woodland and dry forest vegetation cover of over 96%, whilst in the Rio Messalo-Quiterajo area this figure is 71.2% (Timberlake et al. 2011). On the Rondo Plateau in Tanzania, 2755 ha of natural forest were cleared during the Rondo Forest Programme in 1952–1978 and replaced by commercial plantation of exotic tree species. Some clearance of natural forest for subsistence agriculture and for fuelwood collection is an ongoing threat at this site (Clarke 2001). However, a sizeable area of forest remains on the western slopes of the plateau, some of which has regenerated since the cessation of forestry. The gazetting of this site as a Nature Forest Reserve in 2016 may hopefully result in increased protection for the biodiversity there (Wabuyele et al. 2020). With only three locations and a continuing decline in the extent and quality of habitat at the majority of these sites, this species is provisionally assessed as Endangered – EN B2ab(iii).</p></div>	https://treatment.plazi.org/id/193E87C0FF1FFFF7CCD5FE4BFAEC66C3	Public Domain	No known copyright restrictions apply.

Banze 106; K, LMA .</p><p>Distribution and habitat</p><p>Restricted to the Rovuma CoE, known from the Maconde Plateau of Southeast Tanzania and the Mueda Plateau of northeast Mozambique. It occurs in partial or full shade in woodland including in degraded or disturbed areas, at ca 670–950 m a.s.l. elevation.</p><p>Conservation status</p><p>This species is currently assessed on the IUCN Red List as Critically Endangered – CR B2ab(iii) – and possibly extinct (Howard et al. 2020). Whilst the new record from the Mueda Plateau adds a second location, this species could be considered to be severely fragmented given that the two known subpopulations are over 65 km apart, whilst the dispersal potential of this species is likely to be very limited given that it is a small understorey herb. Recolonisation between these isolated subpopulations is, therefore, unlikely to occur. Further, there is very little intact wild habitats still present on both the Maconde and Mueda Plateaux which are highly degraded, with much conversion to agricultural land. At Mueda Plateau, for example, there has been an estimated loss of dense woodland and dry forest vegetation cover of over 96% (Timberlake et al. 2011). Whilst this species appears tolerant of some disturbance, it is unlikely to persist in farmlands. Furthermore, as noted by Howard et al. (2020), it is possible that the Maconde subpopulation is no longer extant. Therefore, the assessment of CR B2ab(iii) is upheld here.</p><p>Taxonomic notes</p><p>Two collections from the Rondo Plateau in southeast Tanzania (G.P. Clarke 35; Q. Luke 12958; both K) are closely allied to this species but have markedly smaller perianth segments. These collections may represent a further species of Rovuma CoE endemic in Celosia or possibly a distinct variant of C. patentiloba . Further material is desirable to fully assess the extent of this variation.</p></div>	https://treatment.plazi.org/id/193E87C0FF13FFF6CF06FC7AFB396652	Public Domain	No known copyright restrictions apply.

It occurs in areas of dense thicket including on termitaria, on edges of temporary water holes and edges of riverine thickets, on alkaline soils, at ca 40–125 m a.s.l. elevation.</p><p>Conservation status</p><p>This species is currently assessed on the IUCN Red List as Vulnerable – VU D2 – as it was previously known from a small range (Extent of Occurrence [EOO] = 366 km 2) and only 2–3 locations within the Selous Game Reserve of Tanzania, and there were some plausible future threats from expansion of camps within the reserve (Beentje et al. 2020). Whilst large areas of the Selous Reserve remain intact, it was included by UNESCO (2021) as one of 52 World Heritage sites in danger, and its conservation outlook is listed as “critical” (IUCN World Heritage Outlook 2020). This is due to a number of recent and ongoing developments within the reserve, including the proposed Julius Nyerere Hydropower Project at Stiegler’s Gorge on the Rufiji River, current and potential future mineral resource exploitation and high levels of poaching of megafauna which may have an impact on the whole Selous ecosystem (IUCN World Heritage Outlook 2020). The new record from Mozambique extends the EOO of this species considerably, to ca 10 625 km 2, and adds one further location. The area around Monapo and Naguema to the east is heavily populated, with extensive conversion of thicket vegetation to farmland, hence the Mozambique location is considered to be experiencing an ongoing threat. With a continuing decline in extent and quality of habitat and with fewer than five locations known, this species is provisionally reassessed as Endangered under criterion B – EN B2ab(iii).</p><p>Taxonomic notes</p><p>The single Mozambique collection is from ca 700 km to the south of the nearest previously known records in Tanzania and is in flower bud only, but it is an excellent match for smaller-leaved specimens of C. fissistyla (e.g., K. Vollesen 4493, Kingupira) and this is a very distinctive species with no close affinity (Verdcourt 1991).</p><p>Please note that, other than the type specimen, we only cite the newly seen Mozambique collection in the "Additional collection studied" section here and do not cite the other Tanzanian collections we have seen.</p></div>	https://treatment.plazi.org/id/193E87C0FF12FFF5CFD9FCBDFF6D6631	Public Domain	No known copyright restrictions apply.
