ESSA YS. 



1 Scutellaria GwUielmi, n. sp. Perilomioides : slender, branched from the base, stolonifer- 

 ous ? leaves membranaceous, minutely pubescent, crenately dentate, the lower round-cordate 

 and slender-petioled, the others ovate or oblong with rounded or truncate base and short-peti- 

 oled, the floral similar but gradually smaller ; flowers solitary in the axils ; peduncles about 

 the length of the calyx ; corolla (" light purple," only three lines long) hardly more than twice 

 the length of the calyx, its lips of nearly equal length ; nutlets surrounded by an abrupt and 

 reflexed denticulate wing, upper face of the disk muricate, the lower as if squamellate. S. 

 hederacea? Gray, in Perry's " Japan Exped." iii. p. 316, and " Bot. Contrib. Proc. Amer. Acad." 

 viii. p. 370, not of Kunth and Bouche\ It appears from a note by Vatke, in "Bot. Zeit.," 1872, p. 

 717, that S. hederacea is identical with the Tasmanian S.humUis, and its nutlets were originally 

 described as echinulate-tuberculate, and by implication wingless. So our plant may be named 

 in honor of Dr. S. W. Williams, who first collected a little of it at Simoda, Japan. Better and 

 fruiting specimens were gathered on the Loo-Choo Islands, by Charles Wright.
