RUMPHIUS'S HERBARIUM AMBOINENSE

Zerumbed majus Rumph. Herb. Amb. 5: 168, excl. t. 68 citata (quae 

 prob. ad C. viridifloram Roxb. pertinet). 



Zerumbed of Rumphius was first placed by Linnaeus under 

 Curcuma rotunda Linn., in Stickman Herb. Amb. (1754) 20, 

 Amoen. Acad. 4 (1759) 129, Syst. ed. 10 (1759) 842, but is 

 manifestly Curcuma zedoaria Rose, where it was placed by 

 Willdenow, with doubt (sub Amomum zedoaria Berg.), and 

 by Roemer and Schultes. It has, by various authors, been placed 

 under Costus arabicus Linn., Amomum latifolium Lam., Amo- 

 mum zerumbeth Koenig, Renealmia exaltata Linn., and Curcuma 

 zerumbet Roxb.

 Zerumbed nigrum Rumph. Herb. Amb. 5: 169. 



This form occurs in Java, cultivated and wild, and, according 

 to Roxburgh, in Burma. Roxburgh placed Zerumbed nigrum 

 Rumph. under Curcuma caesia Roxb., but the Javan plant, which 

 is certainly the same as the one that Rumphius described, agrees 

 better with Curcuma aeruginosa Roxb.

This has been collected in Amboina by Boerlage and is known 

 from Java, Celebes, Key, and New Guinea. Koenig originally 

 reduced Herba spiralis Rumph. to Costus speciosus Sm., in which 

 he has been rather uncritically followed by all recent authors.

 monly cultivated in Batavia, but which is not wild in the Archi-
