P. sp. — Chatham Isl. : Sappho Cove, low bushes on lava in 

 the vicinity of the coast. The specimen has a brownish-gray 

 succulent stem, linear leaves, and rather large pinkish-white 

 flowers. It is a new species to the islands and possibly to 

 science, but the specimen is too poor for accurate description 

 (no. 1511).

 sepals being orbicular rhombic instead of lanceolated, with a 

 medium rib on each, (nos. 1518-1519). Plate III, figs. 9-10.
