MATERIALS FOR A FLORA OF FORMOSA. ‘4 
collected when the flowering season was nearly over. I examined 
a considerable number of the specimens, but I could not find 
more than one or two flowers upon which the description and 
figures in my papar could be based. It may be well conjectured 
that my plant in the normal state of its flowers may have a five- 
lobed corolla with four stamens. I therefore think it better to 
transfer my plant from Loganiacew to Scrophularines, 
referring it to Hemiphragma heterophylla Wain. Another plant 
which I may here mention, is Ellisiophyllum pinnatum Maxtno, 
which was referred to Hydrophyllacex, but, in the present 
work, is transferred to Scrophularinex. In 1871, Maxrmowrcz 
established the same genus upon a Japanese plant in ‘* Mél. Biol. 
Vol. XIII. p. 18”, then named by him as £. reptans. It is very 
probably to be referred to Polemoniacesx, because of its seeds 
which produce a considerable amount of mucilage in the moist 
condition,— a character which is all but peculiar to the same family. 
The plant has also a close relation with Hydrophyllaces, so 
far as the leaves and flowers are concerned. It seemed, therefore, 
rather questionable to Maxmowrcz himself, to what family the 
present genus should be referred. In 1876, the same genus was 
referred to Hydrophyllacesx by Benruam and Hooker. f. in their 
“Genera Plantarum” II. p. 829. <A little later, in 1890, it was 
referred to Scrophularinesz by Barrton in “ Bull. Soc. Linn. 
Paris, No. 103.” Here, he expressed his opinion that the doubtful 
genus belongs neither to Polemoniacee nor to Hydrophyllaceex, 
but to Scrophularinezx. Moreover, he stated that its nearest 
of kin is Litorella of the same family. In 1892, it was again re- 
ferred to Hydrophyllacee by Prrsr in “ Ene. u. Prantu. Nat. Pfl.- 
fam, IV. 3-a, p. 63.” As to the nomenclature of the plant, there had 
been no difficulty, until Mr. T. Makino (1906) called his attention
