Romanzoffia
(named in honour of Count Romanzov, a Russian nobleman, who was a patron of scientific studies). ORD. Hydrophyllaceae. A genus consisting of only two species of low, tufted, hardy perennial herbs, having much the appearance of Saxifrages; they inhabit the sub-arctic regions of Eastern Asia and Western America. Flowers white, unilaterally racemose; calyx segments five; corolla broadly or tubularly campanulate with five imbricated, spreading lobes; stamens five, affixed to the base of the corolla. Radical leaves long-stalked, cauline ones very few, orbicular-reniform, deeply toothed. R. sitchensis, the only species introduced, is a suitable subject for planting on rockwork. It requires much the same culture as Saxifraga (which see). R. sitchensis (Sitcha).* Sitka Water Leaf. fl. white; corolla nearly thrice the length of the calyx; peduncles straight. April. l. long-stalked, somewhat rounded-reniform in shape. h. 4in. Sitcha, 1873. (B. M. 6109; R. G. 748.)
