rain-forests and in the mangrove, generally in scattered spe- 

 cimens. In Sept. 1896 a sterile specimen of this species 

 was found by Boerlage on Lang Eiland. This specimen 

 (No. 71 of his finds) was wrongly named by him Vanda /1 ). 

 In later years this error was corrected by Dr. J. J. Smith. 



From investigations made by Forbes 2 ) it may perhaps be 

 concluded that Cymbidium Finlaysonianum is not autogamous, 

 This may be one of the causes that in 1906 this orchid was 

 much less frequent in the investigated parts of Krakatao than 

 Arundina and Spat/iog/ottis, which are frequently autogamous 

 (See p. 108). 



One specimen of this orchid was found on a steep ravine- 

 wall.

Though some scattered specimens of this tree were found 

 quite near the Casuarina-Qrove mentioned herebefore (p. 154, 

 No. 9) somewhat farther from the coast, there is no reason 

 to consider this tree as an inland species.

1 ) Whether the orchid found in March 1897 by Penzig on Lang Eiland which 

 was named by Boerlage Vanda sulingi Bl. and recorded under this name in P e n z i g s 

 list 3 ), was also this Cymbidium I cannot decide, the specimen not being present in 

 the Buitenzorg Herbarium. Anyhow, it was certainly not Vanda sulingi (at present named 

 Arachnis sulingi Rchb. /?/.) for this epiphyte does not grow on the beach but is restrict- 

 ed to shadowy forests and in 1897 the explorers visited on Lang Eiland only the 

 beach 4 ) where no shadowy forests were seen but only a small grove of Casuarinas, 

 5 6 m- high. Because in Penzig's list all data on habitat, frequency, a. s. o. are 

 lacking, only an examination of the specimen in question can bring the decision, 

 which, at present, is of little or no importance for us.

 recorded P e n z i g's plant either as Vanda sulingi or Arachnis sulingi, proving by 

 doing so, that a vegetation cannot be well described by authors for whom the plants 

 they write upon are no living things but Latin names.
