RUMPHIUS'S HERBARIUM AMBOINENSE 



This is manifestly the form Rumphius described as Laharus, 

 which Hasskarl, Neue Schliissel (1866) 49, thought might rep- 

 resent Nauclea parvifolia Roxb.= Mitragyna parvifolia Korth. 

 of India and Ceylon. The Amboina plant is a true Neonauclea 

 and is identical with Neonauclea moluccana (Miq.) Merr., the 

 type of which was from Buru. Dr. Valeton has indicated to me 

 that this species, although closely resembling Nauclea purpuras- 

 cens Korth., can be distinguished by its linear-lanceolate stipules, 

 which in Korthals's species, as in the Philippine Neonauclea 

 calycina (Bartl.) Merr., are obovate-spatulate ; Nauclea purpu- 

 rascens Korth. is apparently a synonym of Neonauclea calycina 

 (Bartl.) Merr. A large-leaved form, PI. Rumph. Amb. 162, 

 from coral limestone cliffs at Amahoesoe, August 28, 1913, 

 locally known as laharing, was thought by Doctor Robinson to 

 represent Laharus femina Rumph. 



Under Laharus Rumphius described three forms, distinguished 

 wholly on wood characters; these are Laharus lapideus, L. femina, 

 and L. mixta. The first two are certainly Neonauclea, and I con- 

 sider both to be Neonauclea moluccana Merr. ; the status of the 

 third is very doubtful, and it probably does not belong in 

 Neonauclea.

Nessatus Rumph. Herb. Amb. 3: 45, t. 25. 



Regarding this form, Hasskarl, Neue Schliissel (1866) 49, 

 states: "Nauclea spec? s. forsan Anthocephalus indicus Rich.?" 

 The figure is poor and is greatly reduced in size. The leaves 

 are described as 7 to 8 inches long, 2i to 3 inches wide, with 

 few nerves (5 to 7 in the figure), the heads solitary, long- 

 peduncled, and smaller than those of Laharus (Neonauclea 

 moluccana Merr.). Nessatus can scarcely be Anthocephalus 

 indicus Rich., but is apparently a species of Neonauclea allied to 

 N. moluccana Merr.
