it is very generally cited as a synonym of the Linnean species 

 in the early botanical literature. The species is, however, en- 

 tirely distinct from Caryota wrens Linn.

The common and well-known sugar palm is not represented 

 in our Amboina collections. The figure and the description 

 given by Rumphius unmistakably represent the form commonly 

 known as Arenga saccharifera Labill. The illustration has been 

 cited under Borassus gomutus Lour., Saguerus rumphii Roxb., 

 Saguerus saccharifer Blume, and Arenga saccharifera Labill., 

 all synonyms of Arenga pinnata (Wurmb) Merr. ; while Giseke, 

 Prael. Ord. Nat. PL (1792) 90, erroneously reduced it to 

 Chamaerops humilis Linn. Wurmb's specific name is the oldest 

 valid one for the species. Arenga gamuto Merr. was adopted 

 on the assumption that ''Saguerus gamuto Houtt." was published 

 as indicated in Index Kewensis and in the synonymy of Arenga 

 saccharifera Labill. as given by some authors; no such name 

 appears in Houttuyn's work. 



CALYPTROCALYX Blume 



CALYPTROCALYX SPICATUS (Lam.) Blume Rumphia 2 (1836) 103, 

 t. 102, f. 2, 118, 161. 

 Areca spicata Lam. Encycl. 1 (1783) 241 (type!). 

 Pinanga silvestris globosa Rumph. Herb. Amb. 1: 38, t. 5, f. 1, A. 



This species is not represented in our Amboina collections, 

 but it has been minutely described and figured by Blume from 

 Amboina specimens. The Rumphian description and crude fig- 

 ure are the whole basis of Areca spicata Lam. Gaertner, Fruct. 

 1 (1788) 24, referred it to Euterpe glohosa Gaertn., in which he 

 was followed by Giseke, Prael. Ord. Nat. -PL (1792) 92, but the 

 fruit figured by Gaertner is not that of Calyptrocalyx spicatus 

 Blume. Teysmann, quoted by Hasskarl, Neue Schliissel (1866) 



* Retained name, Vienna Code; Saguerus Adans. (1763) is older.
