THE HEIIBARIUM AMBOINENSE. 339 
Calyx quadripartitus laciniis subrotundis. Petala quatuor, 
calyce multo majora, subrotunda, caduca. Stamina plura, peri- 
gyna, petalis longiora. Germen inferum, oblongo-turbinatum. 
Stylus unicus. 
What Rumphius says of a verruca growing below the 
leaves, and spreading out into a substance resembling the 
Cupressus mar inns ^ seems either to relate to some Viscum 
or Psilotum, or to some disease similar to that which we 
observe in Europe on the Betula alba. 
Caput XXXVI. 
Jambosa ceramica, p. 130, t. 41. 
Linnaeus, in the Flora Zeylanica (182-186), described 
as species of Myrtus five plants, which he acknowledges 
scarcely belong to that genus, and which should rather be 
considered as forming one, that should be called Myrcia, 
and of which he gives the natural characters at full length. 
More modern botanists have availed themselves of this hint, 
and Swartz adopted this genus, but chose to give it the 
hard Greek name Calyptranthes. One of these five plants, 
which Linnaeus at first (FL Zeyl. 185) called Myrtus Jhliis 
lanceolato-ovatis, he afterwards, in the Species Plantarum, 
called Myrtus ciimini. The synonyma, which Linnaeus 
quoted for this, were, the Arbor Zeylanica cum 'mum redo- 
lens of the elder Burman (Thes. Zeyl. 27), and the Anka~ 
enda of Herman (Mus. Zeyl. 23). We are indebted to the 
late Dr Dryander (Linn. Trans, ii. 232) for having here 
pointed out an error in Herman ; and that in his Herba- 
rium the tickets of the Madan and Ankaenda must have 
been changed. The synonyma, therefore, of Linnaeus are 
totally wrong, as he described the plants of Ceylon from 
the collection of Herman. The Arbor Zeylanica Cuminum 
redolens and the Ankaenda belong therefore to the Jambo- 
hfera of Linnaeus (Fl. Zeyl. 139) ; while the Prunus In^
