Monographs Details: Cavendishia chiriquiensis var. bullata Luteyn
Authority: Luteyn, James L. 1983. Ericaceae--part I. Cavendishia. Fl. Neotrop. Monogr. 35: 1-290. (Published by NYBG Press)
Description:Variety Description - Leaves usually strong-bullate; 5-7-plinerved with midrib and lateral nerves moderately to strongly impressed above and conspicuously raised beneath, veinlets slightly raised above and usually obscure beneath; petioles inconspicuously puberulent. Rachis (2.5-)6-10.5 cm long; bracteoles ovate to oblong-ovate. Hypanthium moderately to conspicuously apophysate; corolla glabrous or only weakly puberulous the distal 1/3.

Discussion:Cavendishia chiriquiensis is characterized by small caudate-acuminate leaves, pink to red floral bracts, purplish corollas, glandular hypanthia and glandular bracteole-floral bract margins. The calyx lobes are also notable for their callose glands which occasionally appear to break off.

The varieties of C. chiriquiensis are clearly distinguished by features given in the key. Variety bullata shows some dissimilarity between populations in the two known localities; however, all have in common the characters of bullate leaves and usually longer rachises diagnostic for this variety.

Within ser. Lactiviscidae, C. chiriquiensis is probably most closely related to C. panamensis with which it shares densely glandular-margined floral bracts and bracteoles (Luteyn, 1976). The difference in the calyx lobe margins mentioned in Luteyn (1976) is now seen to be inconstant. The lobes of C. chiriquiensis often do have marginal callose glands (similar to C. panamensis) and are not always totally glandular as there indicated. Their often apparent totally glandular nature is now seen to be a function of their extremely small size. Cavendishia chiriquiensis may also serve as a link to sect. Callista by way of endresii, since both species have short, sometimes flexuous rachises, angular to sub-spherical glands at the articulation of the calyx and pedicel, and calyx lobes completely (sometimes in C. chiriquiensis) glandular-callose.
