636. Ito, T. Rhizophoraceae in Japan. (Annais of botany, 13, 1899, p. 465—466.) 

 Als Vertreter dieser Familie finden sich heimisch in Japan Kandelia rheedii, 



Bruguiera gymnorhiza und Uhizophora mucronata; davon reicht die erste bis Kiusiu, die 

 beiden ersten finden sich in Amami Oshima, alle 3 aber kommen zusammen in Uchina 

 (Okinawa oder Great Luchu) und im Yayeyama- Archipel vor. Bei 31° 20' n. B. findet 

 sich also bei Satsuma die X. -Grenze der Mangroven in Japan. Die in Engl. J. 6 S. 63 

 als Uhizophora mucronata bezeichnete Pflanze mnss aber zu Kandelia rheedii gehören.

 XIV, Tokyo, 1897, p. 164-169, 201—206, with 6 figg.) (Japanese.) 



The authoi describes ander his own ohservations the hitherto very little known 

 „mangrove-forests" found in southern Japan. He states that the northern limit of 

 mangroves in .Japan is found in Küre in the Bay of Kagoshima in Satsuma, and 

 extends through the Islands of Amami Oshima and Utchina (the Great Loochoo) to the 

 Yayeyama Archipelago, where thev become as flourishing as in the Malayan coasts. 

 The author points out that the „mangrove-forests" in Satsuma, being situated in 31 ° 

 20' N. lat.. might be considered as the northern limit of Rhizophoraceae. 



Three species of Rhizophoraceae are now described as being known in Japan, vi/. 

 Kandelia rheedii, Wight et Arn., Brngniera gi/inuorrhiza, Lam., and Uhizophora mucronata. 

 Lam. : of whicli the first species only grows in Kiusiu, the southern island of Japan 

 proper; while in Yayeyama Archipelago, all the three species grow together in luxu- 

 riance. He states by the way that a species of Rhizophoraceae collected by Döderlein 

 in Satsuma and determined by Engler (Bot. Jahrb. VI, 1885, p. 63) as Rliizophora mucro- 

 nata does not really belong to that genus. but must he intended for Ktniddia rheedii, 

 which is the only species found in Satsuma. T. Tto.
