Lobivia boliviensis sp nov

Cespitose, in clusters of about 6; plants globular, 8 to 10 cm. in diameter, almost hidden by the long, nearly straight spines; ribs about 20, undulate, broken into short, blunt tubercles; areoles 1 cm. apart; spines 6 to 8, brown, acicular, flexible, often 9 cm. long.

Collected by Dr. Rose at Oruro, Bolivia, in 1914 (No. 18919).

This plant was quite common on the low dry hills east of Oruro, associated with Lobivia ferox, but readily distinguished from it in its very slender spines and in its root system. This species has thick fleshy roots while the other has fibrous roots. It does not do well in cultivation.

Figure 67 is from a photograph of a plant brought by Dr. Rose from the type locality in 1914.
