apex white). Quebradas leading into the Rio Collay, 3-8 km. north of Sevilla de 

 Oro, 7,000-8,300 ft. elev., Camp E-5007 (sprawling shrub 3 m.; leaves deep 

 green above, pale beneath, subnitid on both surfaces; bracts pale pink; corolla 

 basally pink, apically white). 



In my key to the genus (Contr. U. S. Nat. Herb. 28: 463-467. 1932) this species 

 would be sought in the vicinity of C. pubescens (H. B. K.) Hemsl., from which it 

 differs in its less copious indument, generally smaller leaves, more compact 

 inflorescence, and smaller flowers with less conspicuous calyx-lobes. However, 

 the new species is probably more closely allied to C. capitata (Benth.) Hoer., 

 discussed above. From the typical form of C. capitata, C. campii differs in the 

 pubescence of its vegetative parts and flowers, its prevailingly smaller leaves, 

 longer pedicels with smaller bracteoles, eglandular (or sparsely glandular) calyx, 

 and distinctly shorter corolla and stamens. Variability in pubescence is marked 

 in some species of Cavendishia (see discussion of C. bracteata, above), but the 

 combination of characters marking C. campii seems reasonably adequate, although 

 admittedly specific lines in this group of Cavendishia are somewhat arbitrary and 

 in need of field analysis. Another species of this alliance, the Peruvian C. ulei 

 Hoer., has its leaf-blades distinctly 7-nerved and with comparatively highly con- 

 current nerves, and lacks the characteristic white pubescence of C campii,

Santiago-Zamora: Valley of the Rio Zamora, east of Loja, near Zamora, about 

 3,000 ft. elev., June 28-July 1, 1944, Camp E-2 (TYPE US 1,988,931; dupl. NY) 

 (epiphyte on trees over river; bracts deep pink to crimson; corolla white),, 



In its imbricate calyx-lobes, C. zamorensis suggests a relationship with such 

 Colombian species as the recently described C. tenella A. C. Smith (Jour. Arnold 

 Arb. 27: 106. 1946), from which it differs in its short-petiolate leaves with rounded 

 bases, compact and comparatively few-flowered inflorescences, large pedicellary 

 bracteoles, and slightly larger flowers. A specimen which may best be referred to
