sent to me, was the first which led me to count this species beyond doubt 

 among the Flora of Japan. 



Thujopsis dolabrata Sieb. et Zucc. var. Hondai Makino var. now 



Cones globose, Li-2 cm. in diameter, fulvous-brown ; scales 6-8, 

 thick, woody, unequal in size, cuneate ; apex-face square in the upper 

 ones, but transversely oblong in the lower ones, slightly umbonate in 

 centre. 



Nom. Jap. Hinohi-asunaro (T. Makiao). 



Bah. Prov. Mutsu : Near Awomori (Herb. ! Dendr. Inst. Agric. Coll. 

 Imp. Univ. Tokyo, Oct. 1899). 



This differs from the typical species by the shape of the cone. It 

 forms a beautiful and great forest near Awomori, etc. (in Prov. Mutsu) 

 in the northern Japan, where it is commonly known under the name 

 Binohi. The wood lias the best quality and supplies superior timber, 

 while that of the typical one is distorted and inferior. 



I have named it in honour of Dr. Seiroku Honda, Professor of 

 Dendrogical Institute, Agricultural College, Imperial University of Tokyo. 



Sagittaria Aginashi Makino sp. now 



A glabrous aquatic perennial. Khizome erect, thick, densely rooting, 

 without any stolon, furnished with small very numerous pedicellate tuber- 

 eules at the base within petiole-vagin;e. Leaves radical, fasciculate, 

 erect, long-petioled ; lamina nearly perpendicular firmly herbaceous, thickly 

 membranaceous, strongly nervate, sagittate and 12-38 cm. long, but in 

 the inferior ones often simply lanceolate without the basal lobes, 

 linear to broadly lanceolate, acuminate with a subcallose tip, entire, 2~- 

 5-nerved on each side ; basal lobes usually shorter than the terminal lobe, 

 directing downwards with a weak diverging degree, linear to lanceolate, 

 gradually acuminate towards a subcallose tip, entire, 2-4 on the outer 

 side and 1-3 on the inner side of the midrib; petiole elongated, semi- 

 terete, more or less angulate above, vaginate at the base. Scape erect, 

 higher than the leaves, elongate, terete. Raceme narrow, erect ; rachis 

 shorter than the peduncle, subtrigonous-terete, usually not branching; 

 bracts 3-verticillate on nodes, patent, shorter than pedicels, ova to-deltoid 

 or deltoid-subulate, the inferior ones often subulate-lanceolate, with an 

 obtuse tip, herbaceo-membranaceous, scarious and crispate towards the 

 margin ; pedicels 3-whorled, erect-patent, 8-35 mm. in length, the whorls 

 about 5 to 10 to a rachis and distant one another. Flowers moncecious,
