RUMPHIUS'S HERBARIUM AMBOINENSE 



The plate is a fair representation of the common and well-known 

 Lagerstroemia indica Linn. It is the whole basis of Lager- 

 stroemia indica Linn, and of L. chinensis Linn, as originally 

 published, both in the year 1759. As to priority of publication I 

 have no means of determining between volume four of the Amoe- 

 nitates Academicae and the tenth edition of the Systema, but 

 as Linnaeus himself abandons the name Lagerstroemia chinensis 

 in favor of L. indica and as L. indica Linn, is the name univer- 

 sally used for this well-known species, it should be maintained. 

 Lagerstroemia chinensis Linn, does not appear in Index Kewen- 

 sis, but Lagerstroemia chinensis Lam. Encycl. 3 (1791) 375, also 

 typified by Tsjinkin of Rumphius, is listed there as a synonym of 

 L. indica Linn. 



LAWSONIA Linnaeus 



LAWSONIA INERMIS Linn. Sp. PI. (1753) 349. 

 Cyprus Rumph. Herb. Amb. 4: 42, t. 17. 



The common henna is not represented in our Amboina col- 

 lections. Cyprus was originally reduced to Lawsonia spinosa 

 Linn, by Linnaeus, in Stickman Herb. Amb. (1754) 15, Amoen. 

 Acad. 4 (1753) 126, Sp. PL ed. 2 (1762) 498, which is a synonym 

 of Lawsonia inermis Linn. Some authors have referred Cyprus 

 to Lawsonia alba Lam., L. inermis var. spinosa Pers., and L. 

 alba var. spinosa Lam., but these are all synonyms of the common 

 and widely distributed Lawsonia inermis Linn. 



PEMPHIS Forster 



PEMPHIS ACIDULA Forst. Char. Gen. (1776) 68, t. 34. 

 Ly thrum pemphis Linn. f. Suppl. (1781) 249. 



Aegiceras ferreum Blume Bijdr. (1825) 693 p. p. quoad syn. Rumph. 

 Mangium ferreum mas Rumph. Herb. Amb. 3: 120, t. 79, excl. f. A, B. 

 Mangium porcellanicum Rumph. Herb. Amb. 3: 126, t. 84. 



This common and widely distributed strand plant is not rep- 

 resented in our Amboina collections. Mangium ferreum mas 

 as figured by Rumphius presents a flowering branch of Pemphis 

 acidula Forst., but the additional figures A and B are Aegiceras. 

 This mixture of the two species was first pointed out by Teys- 

 mann, as quoted by Hasskarl, Neue Schliissel (1866) 57. The 

 form described by Rumphius, 1. c, as Mangium ferreum femina 

 is probably merely Pemphis acidula Forst. Mangium porcellani- 

 cum Rumph. was first reduced to Lythrum pemphis Linn, by 

 Retzius, Obs. 5 (1789) 4, and as Pemphis acidula Forst. this is 

 the correct disposition of it.
