Description
|
Erect, often arching, terrestrial shrub, 2.5-3 m tall; stem base ca. 2.5 cm in diameter; mature branches terete, glabrous, ca. 1 cm in diameter; bark yellowish brown; immature branches and twigs of the new growth bluntly angled or ribbed, minutely striate, glabrous. Leaves elliptic, lance elliptic to ovate lanceolate, 9- 16 cm long, 3-6 cm wide, basally acute to narrowly obtuse, rarely rounded, apically acuminate to somewhat caudate acuminate, olive green to grayish green above and tannish green beneath when dry, glabrous but with scattered, ele- vated, reddish globular glands, the glands 0.1-0.2 mm in diameter along the up- per leaf surface, often caducous usually leaving a reddish or blackish papillate scar; 5(-7)-plinerved, the innermost lateral nerves often arising 2-3 cm above the base, the midrib impressed above, raised and conspicuous beneath, the lateral nerves impressed above becoming plane to slightly elevated distally with the outer lateral nerves often obscure beyond the middle, raised and conspicuous beneath, the veinlets raised and usually conspicuous above, obscure to slightly raised beneath; petioles terete, slightly flattened adaxially, rugose, (2.5-) 6-8 (-10) mm long, 2-2.5(-3.5) mm in diameter, glabrous or infrequently puberluent, golden tan. Inflorescence viscid, 11-21(-37)-flowered, often the several lowest nodes sterile; rachis flattened, gradually tapering and often flexuous distally, conspicuously ribbed and minutely striate, glabrous or rarely puberulent, (3-) 8-17 cm long, to 5 mm in diameter at the base, pink to dark pink when fresh with minute, peltate, globular reddish glands along its length and especially at the base; floral bracts glabrous or sparsely ciliate along the distal 1/3 of the margin, oblong to oblanceolate, rarely obovate, basally narrowed to a slightly clasping base, apically rounded or narrowly obtuse to acute, (2-) 3-5 cm long, (0.6-) 1-2 cm wide, pink, marginally with 7-23 dark red, globular, peltate or sessile glands ca. 0.7 mm in diameter; pedicels subterete, swollen distally, striate, glabrous (11-) 15-19 mm long, 1-1.5 mm in diameter, pink, with few, scattered, globular, reddish glands; bracteoles ovate to lanceolate, 1.5-2(-4) mm long, 1-2 mm wide, pink, with few, scattered, dark red, globular glands marginally and apically. Flowers with the calyx glabrous, 4-6 mm long, the tube cylindric or spreading, rugose to strongly ribbed, 1.5-2 mm long, 2.5 mm in diameter, not basally en- larged, green, usually with dark red, globular to disc-shaped, peltate glands ob- scuring the surface, the limb cylindric campanulate, smooth (2.5-)3-3.5 mm long including lobes, pale green to pinkish with scattered, globular to disc-shaped, peltate glands, the lobes triangular, obtuse, 1-1.5 mm long, 1.5 mm broad, erect after anthesis, marginally glandular callose thickened with the glands contiguous at the lobe apices, pinkish green with dark pink margins; sinuses broadly rounded; corolla constricted basally, narrowed to the throat, 2.5-3.5 cm long, 8-10 mm in diameter, glabrous, or pilose and glabrous at the constricted base, white, the lobes triangular, obtuse, 1-2 mm long; stamens 27-30 mm long, the filaments slightly coherent basally, strigose distally, alternately 4-6 mm and 10-13.5 mm long, white, the anthers including the tubules alternately 17-20.5 mm and 25-27 mm long, yellow, the thecae 7.5-11 mm long; style 25-31 mm long. Berry not seen.

Note

Cavendishia panamensis like C. chiriquiensis is endemic to western Panama. Both species are characterized by glandular-margined floral bracts and bracteoles, and gland-covered calyx tubes. In these respects they are reminiscent of C. pseudostenophylla. However, the linear leaves of C. pseudostenophylla at once distinguish that species. Cavendishia panamensis differs from C. chiriquiensis by a basic difference in calyx lobe glands. In C. panamensis the callose-thickened portion of the calyx lobe is strictly marginal, while in C. chiriquiensis the entire calyx lobe is callose thickened and appears occasionally to break off.
