), these drying yellowish tan; new growth densely papillate and pubescent like the stems, the trichomes tangled and interwoven; bark of older stems pale brown, becoming somewhat corky and glabrescent. Sympodial units difoliate, the leaves geminate, the leaves of a pair differing in size and shape. Leaves simple; blades of major leaves 2.5-4 (8) cm long, 1-2.5 cm wide, elliptic to narrowly elliptic (lanceolate in
); adaxial surfaces shiny, sparsely and unevenly pubescent with dendritic trichomes with congested branches like those of the stems, these denser along the midrib and principal veins; abaxial surfaces densely dendritic pubescent (lamina barely visible in
; apex acute or more often acuminate; petiole 0.4-0.6 cm long, densely dendritic-pubescent like the stems; blades of minor leaves 0.6-0.7 cm long, 0.6-0.7 cm wide, orbicular or heart-shaped, similar in texture and pubescence to the major leaves; base cordate or rounded; margins entire or revolute; apex rounded; petiole absent or less than 0.1 cm long, densely dendritic-pubescent. Inflorescences axillary fascicles of 1-3 flowers, only one open at a time, densely dendritic-pubescent; pedicels at anthesis 1-1.2 cm long, ca. 1 mm in diameter at the base, ca. 1.5 mm in diameter at the apex, erect or spreading, densely pubescent with golden dendritic trichomes with congested branches like those of the stems and leaves, articulated at the base; pedicel scars tightly packed in the leaf axils, Buds long-ellipsoid, the corolla strongly exserted from the calyx tube before anthesis. Flowers 5-merous, probably heterostylous and unisexual, no styles seen in the only flowering specimen seen (
), the plants possibly dioecious. Calyx tube ca. 3 mm long, 3-3.5 mm in diameter, cup-shaped, densely golden dendritic-pubescent with trichomes like those of the pedicels, thick and coriaceous (fleshy in live plants?), without appendages, the rim slightly thickened. Corolla 1.5-2 cm in diameter, purple (mauve), deeply stellate, lobed nearly to the base, interpetalar tissue absent, the lobes 6-9 mm long, 2-3 mm wide, spreading, thick and fleshy, adaxially glabrous, abaxially moderately pubescent with simple uniseriate trichomes 0.25-0.5 mm long, if these branched then merely forked, the branches not congested, the tips and margins densely papillate, the tips cucullate. Stamens equal; filament tube minute; free portion of the filaments 1-1.5 mm long, glabrous; anthers 5-7 mm long, 1-1.2 mm wide, long-ellipsoid and tapered at the tips, yellow, poricidal at the tips, the pores distally directed, not elongating with age. Ovary not seen. Fruit and seeds not known. Chromosome number not known.

is known from only two localities and has been very rarely collected. It could be assessed as Data Deficient (DD), but given the threats to New Guinea forests more broadly I suggest it warrants assessment as Critically Endangered (CR [B1,2a,b(iii,iv)]); more collecting and a better understanding of its distribution are priorities.
is a distinctive species with small leaves, branched trichomes with densely congested branches, and 1-3 flowers per leaf axil. It shares trichome type with
, but that species is a coarse herb rather than a straggling shrub, has many flowers on a short inflorescence axis rather than 1-3 flowers per axil, and smaller flowers with copious interpetalar tissue (1-1.2 cm in diameter with interpetalar tissue in
are not yet known. Other than the type, that has thick, coriaceous leaves with somewhat revolute margins, the only other specimen I have seen that is attributable to this species (
) is sterile; the leaves on this specimen are much thinner in texture and more elongate, indicating this may represent a juvenile pre-flowering individual.
