I have been in Micronesia from December 1914 to January 1915, 

 and visited the islands of Truk, Ponape, Kusai, Jaluit,* Angaur, Palau, 

 Yap and Saipan. During this voyage, I made a fairly large collection of 

 plants, and was interested very much in obtaining some idea of the 

 vegetation of the tropical Pacific islands. 



As regards the phytogeography of this Archipelago, the main source 

 of our. knowledge: is Volkens' " Die Vegtation der Karolinen mit 

 besonderer Beriicksichtigung der von Yap ", shorter sketches of the 

 vegetation having been published by Kittlitz and Safford. Yet the 

 informations on the flora of Micronesia is so scanty that, my collections 

 contain some additions to our knowledge, which 1 propose to publish 

 in following lines. 



8. Elaeocarpus Kusanoi Koidz. nov. sp. 



Haec planta El. samoensi affinis sed foliis oblongis 9-16 cm. longis 

 4.5 — 7.5 cm. latis breviacuminatis margine repando-undulatis vel 

 undulato-crenatis basi rotundatis, petiolis 2.5 — 5.0 cm. longis ; stami- 

 nibus albo-pilosisque differt. 



Arbor magna ramis vetustioribus fusco-cinerascentibus tuberculatis, 

 junioribus fuscis glabris densius lenticellatis. Folia ad summos rami 

 conferta coriacea oblonga obtuse breviacuminata rarius obtusa basi 

 rotundata margine crenato-repanda vel obscuriter repauda 9-16 cm. 

 longa, 4.5-7.5 cm. lata, glabra, subtus in axillis nervorum glandulis 

 perforatis instructa, nervis utrinsecus 8-9 supra leviter subtus magis 

 elevatis, venulis elevato-reticulatis satis conspicuis ; petiolis 2.5—5.0 cm. 

 longis glabris subteretibus ad basim lamina? carnoso-subgeniculatis.
