Reinwardtiodciidron. 75 



Barnes remarks in his field notes communicated by Merrll: 

 "Tree 10 m high, 5 cm in diam., first branches at 6,5 m. The bark 

 is gray, somewhat rough, with an odour of cedar. Wood white and 

 hard. Tagalog: "malacamanga"." 



In a letter received from Mr. Merrill, he mentions this plant 

 and remarks: "This species so far as the flowers are concerned appears 

 to be Lansium, but the fruit is entirely different from other species 

 m the same genus. I may be wrong in my interpretation of the 

 form but have placed the name Lansium monophyllum tentatively 

 on this form". Koorders, in Verslag eener Botan. Dienstr. door de 

 Minahasa p. 389 (1898), has described, from Minahasa, a new genus, 

 Reimvardtiodendron , which accords so fully with the characters of 

 Merrill's specimen that I have no doubt of the very close affinity 

 of this plant with that of Koorders'. The original of Koorders' not 

 being in the Berlin herbarium and it being impossible to determine 

 Merrill's specimen from the diagnosis, on account of the imperfect 

 description of the leaves, it seemed advisable to describe the plant 

 as new. I have called it Reinivardtiodendron MerrilUi. In the 

 appendiculate anthers, especially in those of the lower row, is to be 

 found the most important difference between the genera Eeinwardtio- 

 dendron and Lansium, a difference so slight, that perhaps later the 

 genera will be united with Lansium. Harms, in Nachtrag II, in 

 Engler und Prantl's Pflanzenfam.. p. 37 retains both genera. It is 

 also worthy of notice that the Reinivardtiodendron Meirillii has 

 simple leaves, a character, however, not of sufficient importance to 

 separate it from Lansium. It must be taken into consideration that 

 for instance, in Aglaia, the species of which genus have pinnate 

 leaves, there occur plants with simple leaves. In the preceding 

 diagnosis I have given a description of the fruit of Merrill's plant. 

 An examination of the fruit of Lansium domesticum, from material 

 brought by Volkens from Buitenzorg, gave the following results. 

 The seeds are envelopped in a fleshy arillus that is manifestly 

 wanting in Rcinwardtiodendron MerrilUi. The cotyledons lie one 

 above the other, similarly to those in Reinivardtiodendron, and differ 

 from each other considerably in size, at least the difference is deci- 

 dedly more than in those of Merrill's plant. 



Jack, in Trans. Linn. Soc. XIV, p. 115 t. IV, gives the first 

 good description of Lansium domesticum and his figures agree ad- 

 mirably with my observations. In the form of the fruit the two 

 plants are remarkably alike, but the pericarp of Reinivardtiodendron
