Description:
Species Description - Spreading epiphytic shrub, mature branches subterete, puberulent, glabrate; bark grayish-brown; twigs subterete, bluntly angled, puberulent, reddish-brown. Leaves lance-elliptic, (1-)2-3.5 X (0.7-)1-1.5 cm, basally obtuse to rounded, apically acute or obtuse, sometimes short-apiculate, ciliate, minutely puberulent along midrib above; 3-5-plinerved from near base, midrib and inner pair of lateral nerves conspicuous, impressed above and raised beneath, outer pair of lateral nerves and reticulate veinlets raised above and obscure beneath; petioles subterete, slightly channeled adaxially, puberulent, 2-2.5 mm long and ca. 1 mm diam. Inflorescence ca. 6-flowered, encircled at base by numerous, subcoriaceous, ovate to oblong, ciliate bracts to 16 mm long; rachis subterete, bluntly angled, glabrous or minutely puberulent, to 1 cm long and 0.8 mm diam.; floral bracts oblong, oblanceolate, ca. 20 X 7 mm, apex rounded and shallowly emarginate, glabrous, dark violet when fresh (fide label data); pedicels terete, swollen distally, glabrous, 5-6(-8) mm long and 0.8(-1.4 distally) mm diam., provided at distal tip with subspherical to angular glands to 0.2 mm diam. or 0.3 mm long; bracteoles basal, oblong, 0.7 mm long, glabrous, margins apparently glandular-callose through distal 2/3. Flowers: calyx glabrous or hypanthium basally puberulent, 3.2 mm long; hypanthium cylindric, weakly 5-ribbed, 1.5 mm long, basally narrowly apophy-sate; limb erect to spreading, 1.7 mm long; lobes triangular, acute, ca. 1 mm long, slightly connivent after anthesis, each margin provided with an oblong somewhat crescent-shaped, callose gland, these contiguous or separate at lobe tip; sinus broadly rounded to nearly flat; corolla cylindric, distal half moderately or densely puberulent to short-pilose, ca. 15 mm long, light violet when fresh (fide label data), lobes oblong, obtuse; stamens (taken from flower not quite in anthesis and corolla 14 mm long) 12.7-13 mm long; filaments slightly coherent at base, ciliate, alternately 1-2 mm and 3.2-3.5 mm long; anthers alternately 12.4-13 mm and 11 mm long; thecae 3.5-4 mm long; style 13.5 mm long. Berry not seen.

Discussion:
Cavendishia amoena is characterized by a combination of small, apically acute or obtuse leaves, few-flowered inflorescences, short rachises, angular glands at the pedicel/calyx articulation, short corollas, and violet color of the floral bracts and corollas.In 1950, A. C. Smith suggested a relationship between amoena, C. angustifolia, and C. dugandiana. Detailed examination of the calyx and bracteole glands confirms this for C. amoena and C. angustifolia, but eliminates C. dugandiana, of which the relationships are with C. bracteata of sect. Cavendishia. Cavendishia amoena is most closely related to C. angustifolia although they are quite distinct. They are discussed more fully under C. angustifolia.
