c. Under side of leaves green, grayish, or yellowish (violet in forms of No. 14).
Very small: lvs, 2-3 in. long, and 1 in. wide, oblong-lanceolate, somewhat acuminate, green and shining above, the rib in a feathered white stripe, paler beneath. Brazil. - Probably the smallest cultivation Calathea.

Brazil. Gn. 2, p. 3. - Considered by some to be a variety of C. rotundifolia, Koern. C. farinosa and C. ovalifolia are probably stages in the development of this plant or perhaps slight varieties.

Brazil. B.R. 932. - Perhaps to be referred to C. grandiflora, Schum.
Habit dwarf and compact: growth bearing 2- 4 leaves, usually with 3, and from 6-18 in. high, erect at first, arching towards the apex; blade lanceolate, unequi-lateral, 4-9 in. long, pale yellowish green with a row on either side of the midrib of arrowhead-shaped blotches of dark green which give this plant a distinct and pretty appearance, the under side in plain yellowish green; petiole slender, erect, 6-12 in. long; sheath extending only to about a quarter of its length, upper part terete.
Habit dwarf, compact, 1/2-2 ft. high: growths with 2-5 leaves; blade elliptic-lanceolate, slightly oblique, 3-12 in. long, glabrous, acute, upper side light green, pinnately striped with white from apex to base, underside pale dull green shaded between the veins with slightly lighter yellowish green; petiole slender, erect or spreading, 3-15 in. high, light green, glabrous; sheath extending from one-third to one-half its length, upper part terete.
