LOBIVIA

(An anagram of Bolivia, the home of most of the species, though some are found also in Peru and Argentina.) The plants are globular, the flowers rather large and funnel-shaped, with a short tube. There are at least 45 species in the genus, all easilv cultivated and free flowering.

Lobivia Pentlandii. Bolivia and Peru. Probably the best known species, it includes many varieties of desirable plants, spherical in shape, bright green, with 12 deep furrowed ribs. Radial spines number 7 to 12, of brownish colour; only 1 central spine. The flowers are borne on the side of the plant, and are orange-red to carmine.

Lobivia Cumingii. Bolivia and Peru. Differs from L. Pentlandii both in form and flower. It produces small glaucous-green globose bodies, whose tubercles run spirally in about 18 rows. Each tubercle bears about 20 straight marginal spines, with 2 to 8 slightly longer central spines. Flowers are borne on the sides or near the top, and are orange-red with a yellowtube. Easy to grow in cultivation and very free flowering.

Lobivia cinnabarina. Bolivia. A very beautiful species, the flowers remaining in bloom for three days. The stem is globular, and shining dark green, with 18 to 21 ribs. Radial spines number 8 to 10, central spines 2 to 3. The flowers are scarlet to carmine with dark red stamens.

Lobivia famatimensis. N. Argentina. A small plant. Ribs number 20, and are irregular and warty, with many whitish or yellowish short spines covering the stem. Very free flowering. The colour of the flower varies from yellowish-white to red.

Lobivia mistiensis. S. Peru. The stem is globular or conical, with 25 to 30 ribs. Radial spines number 7 to 9, and are spreading. The flowers are pink.

Lobivia hertrichiana. Peru. Easily grown from seed. The stems are glossy pale green, with about 11 ribs. Radial spines number 7, with only 1 central spine. An excellent beginner s plant, flowering from quite young.

Only a few species comprise this genus. They usually grow in tufts with globular stems. The flowers are large and yellow, with a slender hairy and scaly tube.

Mediolobivia duursmaiana. Argentina. The stems are a dark leaf-green, with many areoles bearing 10 thin radial spines and I central spine tipped with yellow. Flowers funnel-shaped, orange-yellow with a white throat.
