Discussion:
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 concurrent nerves, and lacks the characteristic white pubescence of C. campii.
