Since the publieation of the Enumeratio Plantarum Formosana- 

 rum and Flora Montana Formosae, a large number of collections 

 was sent to the present author for determination by the Govern- 

 ment of Formosa. As he found it very unsatisfactory to work up 

 so big a collection only in the Herbarium at Tokyo, he thought 

 it very necessary for his work to see all the plants represented in 

 the prineipal herbaria of the West. With this intention, he first 

 went to Kew, taking all his materials with him. There he pursued 

 his work with speeimens of the floras to which the flora of For- 

 mosa is more or less related. After finishing his work at Kew, he 

 went to the herbarium at Paris, then to Dahlem, and finally to 

 St. Petersburg. During his work in these herbaria, he was suc- 

 cessful in identifying some plants with species preserved in them. 

 Still, many of his collections are not there represented. It is, as 

 he says, higly probable that they are species not yet described. 

 The plants mentioned in the present work are mostly of species 

 newly described and, if not, they are new to the flora of For- 

 mosa. In this work, the author has endeavoured to mention all 

 the species recorded from Formosa, which have appeared in 

 different small publications, since the issue of the Enumeratio Plan- 

 tarum Formosanarum and Flora Montana Formosae. So that, prac- 

 tically speaking, the work is an exhaustive Supplement bringing 

 the above mentioned publications up to date. As the total number 

 of the plants of the island know to us up to date, he has given 2660 

 species belonging to 836 genera and 156 families. The following list 

 shows those genera which are newly added to the flora of the island: 

 Isopyrum, Cochlearia, Canarium, Brasenia, Thespisia, Allophylliis, 

 Uvaria, Suriana, Pometia, Albissia, Cotula, Juglans, Pirus, Codo- 

 nopsis, Platycarya, Cotoniaster , Embelia, Castanea, Prinsepia, Maba, 

 Halophila, Callitriche, Melodinns, Oberoma , Bupleurum , Heterostemma , 

 Cirrhopetalum, Pimpinella , Paulownia , Chrisoglossum , Phellopterus, 

 Hemiphragma , Collabium , Oreomyrrhis, Titanotrichum , Spathoglottis, 

 Osmorrhisa, Oreocharis, Bletia, Angelica, Hemigraphis, Pleione, 

 Abelia, AcrocepJialus, Sarcochilus, Nauclea, Lycopns, Saccolabium, 

 Guettarda, Melissa, Cleisosloma, Coprosma, Cryptocarya, Appendicula, 

 Triplostegia, Illigera, Aphyllorchis, Lagenophora, Chamabaina, Galera, 

 Herminium, Cladium, Hemipilia, Thuarea, Floscopa, Eremochloa, 

 Phiellia, Acrophorus, Zannichellia , Oleandra, Remirea, Monachosorum. 

 The plants newly described tn this work are very numerous,. 

 amounting to more than four hundred species. A few plants are men- 

 tioned under families different from those to which they are formely 

 referred; for exemple: Rehmannia is mentioned by another name 

 of Titanotrichum Oldhami, and is transferred from Scrophulari- 

 neae to Gesneraceae; Ellisiophyllum reptans is mentioned as 

 EllisiophyUum pinnatum , and is transferred from Hydrophyllaceae 

 to Scrophularineae; Hoeckia Aschersoniana is mentioned by another 

 name of Triplostegia glandulifera , and referred to Valerianeae. 

 For comment as to these alterations, he has discussed the question 

 very precisely under Introduction. An extremely remarkable case 

 given in this work, is the oecurrence of Oreomyrrhis in Formosa, 

 which genus is exclusively peculiar to the high regions ot the 

 Southern Hemisphere. Another case of novelty is the addition 

 of two families to the present flora. They are Hernandiaceae 

 and Myristiceae. B. Hayata.
