really a native of Formosa, and thal the occurence in the Latter island must be explained 

 ae ;, case of „scattered distribution". Bis conclusion may be quoted as follows: 



Euphorbia tirucalli L., bitherto known only from Zanzibar in it- wild State, 

 finds its mother-land also in Formosa beyond eighty degrees to the east. This affords 

 ;i good example ofa remotely scattered distribution or rather of a „Relikt- Endemismus" ; 

 iml it is highly probable thal this plant still growing wild in the-above two localities, 

 and only found in cultivation or in uaturalized state in India, Burmah. Eastern-I'eninsula. 

 and in iimiiiv .M.il.i\ ;ind Polynesian Islands, w;is once preponderant in former Earth- 

 Period in a more extensive area, probably ranging from Airica to New Zealand."

Miscellaneous notes of the author's visit to the island of Shikoku in 1896. The 

 author gives some accounts of Ins ascent on the moutains of Ishidzuchi-yama (alt. 4950

 Tschonoskiana, Pinus pentaphylla, Potentüla fruticosa var. fl. alb., Geranium robertianum, 

 Kirengeshoma palmata etc. In Yokogura-yama he collected 136 species of Phanerogams. 

 He also visited a small island, known as Kashiwa-jima, in the sea of Tosa. 



The author found Fiats wightiana growing in many places of Sikokn. Various 

 |ilant-diseases caused by parasitic fungi drew his attention, among which he teils of 

 the stem and leaves of Nicotiaua tabacum being attacked by Macrosporium and Cercospora, 

 Setaria italica infested by Sclerospora graminicola, the leaves of Arctium lappa by 

 Sphaerotheca, the stem of potatoes by Phytophthora infestans (?), etc. Turning to Phane- 

 rogams, he observed Villebrunea peduneulata, Shirai, some species of Symplocos, Yitis, 

 Actinirfia rufet, Tsuga japonica, etc. T. Ito.
