Description:
Species Description - Totally glabrous shrub; branches subterete, smooth or minutely striate, bluntly ridged. Leaves oblong to ovate-lanceolate, 5-7 X 1.6-2.6 cm, basally rounded, apically long-acuminate, slightly revolute at very base, nitid; 3(-5)-plinerved from near base, midrib and lateral nerves impressed and conspicuous above, raised beneath but only midrib obvious, reticulate veinlets obscure on both surfaces; petiole subterete or slightly flattened dorsally, rugose, 3.5-5.5 mm long and 1.5-1.8 mm diam. Infloresence 5-7-flowered; rachis sharply angled, striate, 1.3-2.5 cm long and 1 mm diam., nodes raised and very prominent; floral bracts elliptic to broadly ovate, 14-17 X 10-15 mm, marginally glandular-fimbriate; pedicels subterete, rugose, 3-4 mm long and 1.2 mm diam.; bracteoles located ca. midway up pedicel, oblong, 2 X 1 mm, marginally glandular-fimbriate. Flowers: calyx 7-10 mm long; hypanthium cylindric or somewhat obconic, rugose, 2-3.5 mm long, apophysate proximal 0.8-1 mm, the apophysis not or only slightly spreading; limb cylindric-campanulate to erecto-patent, 5-7 mm long, irregularly and unequally divided into 5 oblong-triangular lobes 2-5 mm long, seemingly erect after anthesis, marginally bearing ca. 3-5 remotely spaced fimbriae; sinus acute; corolla cylindric, 17-18 mm long, "rose at base, green at tip," lobes deltoid, obtuse, ca. 2 mm long; stamens ca. 10-11 mm long; filaments slightly coherent at base, alternately ca. 2.5 mm and 4.5 mm long; anthers alternately 8.5-9.5 mm and 89 mm long; thecae 2.5-3.5 mm long; style ca. 20 mm long, short-exserted at anthesis. Berry not seen.

Discussion:
Cavendishia dendrophila is a puzzling species of which more collections are needed. In corolla color and leaf size and shape it is similar to some forms of C. bracteata; however, its calyx is more like that of C. tarapotana and other members of ser. Cavendishiae which have an apophysate hypanthium, elongate limb, and fimbriate lobes. The irregular fissuring of the calyx is unique in Cavendishia, being found elsewhere only in Psammisia. The short stamens (about half as long as the corolla), and proportionately long corolla lobes are also unusual for Cavendishia but are commonplace in Psammisia. I have doubts about recognizing this taxon which may be an intergeneric hybrid (with Psammisia penduliflora?) or even a monstrosity, but I am maintaining it as a relative of tarapotana for the present.Within ser. Cavendishiae, C. dendrophila is somewhat intermediate between C. macrocephala-C. cuatrecasasii on the one hand, and colombiana-C. tarapotana on the other. In its short calyx limb (5-7 mm long) and lobes (2-5 mm long) and short-apophysate hypanthium it resembles the latter pair, but in its triangular-oblong calyx lobes and erect calyx limb and lobes it resembles the former. More collections and intensive field studies in the type locality are required to clarify its status.
