lobes of the calyx, inserted at its base, sessile, glabrous, subfusiform, 3-angled, few-seeded, with the persis tent and 
hardened subterminal style turned outward, dehiscing by the ventral suture, 2 lines long. Seeds pendulous, 
linear, exalbuminous, pale, 14 lines long; testa membranaceous, thin. 
Specimens of this plant were collected by Mr. Kano Watanabe on the bank of the river Watari-gawa (湊川) 
in the province of Tosa, on the 15th. of October, 1891. The specimens have fruit only, but there is no doubt 
that the plant is a new species, It is related to Spirea bracteata, Zabel (.S. nipponica, Maxim., in Mel-Biol., vol. 
xii., pp. 455 et 934), which have orbiculate-obovate or broadly elliptical leaves, It seems to be also allied to S. 
mongolica of Maximowicz (Mel. Biol., vol. xi., p, 216), as may be inferred from his description.

Saxifraga Watanabei, nov. sp. 
Nom, jap. Watanahe-so. ツタ ナベ サウ ・. 
This is a new species of Saxifraga discovered by Mr. Kano Watanabe at Nanokawa-mura in the province of 
Tosa, on the 12th. of July, 1889. It is nearly related to Saxifraga tellimoides, Maxim., but the leaves of the 
former are more deeply lobed than those of the latter; and the petals of the former are linear, whereas thoseof the 
latter are spathulate. In the next number of this magazine a figure and description of the former will be given.
