Description:
Species Description - Epiphytic or terrestrial shrub, sometimes lianoid; mature branches terete, minutely striate, puberulent, brown; bark reddish-brown; twigs subterete to bluntly angled, minutely striate, puberulent, brown. Leaves linear-lanceolate to linear-elliptic, 9-14 X 1-1.5 cm, basally broadly obtuse or rounded, slightly cordate, apically long-attenuate, acute, glabrous, margins strongly revolute; 3(-5)-plinerved, midrib deeply impressed above, raised and conspicuous beneath, lateral nerves and veinlets raised and conspicuous above, slightly raised but obscure beneath; petioles subterete, rugose, 2-3.5 mm long and 1-2 mm in diam., densely puberulent. Inflorescence viscid, 12-20-flowered with lowest nodes sterile; rachis long-tapering, bluntly angled, minutely striate, glabrous, 5-15 cm long and ca. 1-1.5 mm in diam., with few globular glands scattered along rachis; floral bracts with venation prominent, often somewhat ribbed, oblong or oval-elliptic, (13-)19-27 x (5-)7-11 mm, basally narrowed and rounded, apically rounded or acute and short-ciliate, pink (fide label data), margins provided along each side with (3-)7-12 sessile, globular glands to 0.2 mm in diam.; pedicels subterete, to 8 mm long and 1 mm in diam., glabrous, provided with few, globular glands; bracteoles located 1 mm below articulation of pedicel and calyx, completely enveloping flowers in bud, clasping calyx and corolla at anthesis, oblong, oblong-elliptic or oblanceolate, 25 X 10 mm at anthesis, basally rounded, apically broadly rounded, glabrous or marginally short-ciliate, marginally with up to 15 globular glands. Flowers: calyx glabrous, 6.5-7.5 mm long; hypanthium cylindric, slightly rugose, 1.5-2 mm long and 3.5 mm in diam., basally slightly apophysate with globular glands primarily around margins of apophysis but with a few onto tube; limb campanulate to erecto-patent, smooth or slightly ribbed, 5-6 mm long; lobes triangular, 2 mm long, erect after anthesis, margins conspicuously glandular-callose, the thickenings nearly contiguous at lobe apex; sinus obtuse or rounded; corolla cylindric, ca. 32 mm long and 6 mm in diam., pink, densely short-pilose in distal 1/3, lobes triangular, 2 mm long; stamens 27-28 mm long; filaments short-pilose in distal half, alternately 4-4.5 mm and 7.5-8 mm long; anthers alternately 24-24.5 mm and 20 mm long; thecae 6-7 mm long; style 31-33 mm long. Berry not seen.

Discussion:
Cavendishia pseudostenophylla is characterized by linear-lanceolate to linear-elliptic leaves, large (to 27 mm long) bracteoles which are located just beneath the calyx/pedicel articulation, and viscid flowers with the odor of wintergreen. The report of the wintergreen odor (Mori & Kallunki 6168) is the first for a species in ser. Lactiviscidae.Although the leaves of C. pseudostenophylla are superficially similar to those of C. stenophylla because of linear outline and revolute margin, the venation is quite different, C. pseudostenophylla plinerved, C. stenophylla pinnately nerved. Furthermore differences in bracteole size, attachment, and position, those of C. pseudostenophylla being up to 27 mm long, articulate, and apically inserted whereas those of C. stenophylla do not surpass 3 mm and are continuous at 1/3 to halfway up the pedicel, also serve to distinguish the species.Cavendishia pseudostenophylla is without close relatives in ser. Lactiviscidae. Additional collections are needed before its morphological variation and evolutionary affinities are fully understood.
