RUMPHIUS'S HERBARIUM AMBOINENSE 



described as ruber simplex is the ordinary type with normal red 

 flowers. Other forms described are the one with yellowish 

 double flowers and one with normal, pale or nearly white flowers. 

 This commonly cultivated plant does not occur in our Amboina 

 collections, but is doubtless common in Amboina in cultivation, 

 as it is in all parts of Malaya. 



THESPESIA Solander 



THESPESIA POPULNEA (Linn.) Soland. ex Corr. in Ann. Mus. Paris 9 

 (1807) 290. 



Hibiscus populneus Linn. Sp. PI. (1753) 694. 

 Thespesia macrophylla Blume Bijdr. (1825) 73, 106. 

 Novella litorea Rumph. Herb. Amb. 2: 224, t. 7U. 



Amboina, Amahoesoe and Binting, Robinson PL Rumph. Amb. £98, 

 August and September, 1913, along the strand. 



Novella litorea was first reduced by Linnaeus to Hibiscus 

 populneus Linn., in Stickman Herb. Amb. (1754) 10, Amoen. 

 Acad. 4 (1759) 121, Syst. ed. 10 (1759) 1149, Sp. PL ed. 2 (1763) 

 976, which, as Thespesia populnea Soland., seems to be the correct 

 disposition of it. Blume, however, Bijdr. (1825) 73, has pro- 

 posed Thespesia macrophylla as a distinct species, apparently 

 based wholly on the Rumphian figure and description, and many 

 authors have recognized it as a valid species. Any large series 

 of specimens from the Malayan region presents such relatively 

 great variations in the characters by which the two forms have 

 been distinguished, that I am by no means certain that they are 

 specifically distinct and prefer to retain the Amboina plant under 

 the older name.* 



GOSSYPIUM Linnaeus 



GOSSYPIUM BRASILIENSE Macf. PI. Jam. 1 (1837) 72. 



Gossypium lapideum Tussac, Fl. Antil. 2 (1818) 67, nomen nudum. 



Gossypium latifolium Rumph. Herb. Amb. 4: 37, t. 13. 

 Amboina, Koesoe koesoe sereh, Robinson PI. Rumph. Amb. August 

 23, 1913, locally known as kapas. 



The Rumphian species was first reduced by Linnaeus to Gos- 

 sypium arbor eum Linn., in Stickman Herb. Amb. (1754) 15, 

 Amoen. Acad. 4 (1759) 126, Syst. ed. 10 (1759) 1148, Sp. PL 

 ed. 2 (1763) 975, where it certainly does not belong. Lamarck 

 cites it in the original description of Gossypium vitifolium, 

 Encycl. 2 (1786) 135, but Lamarck's type was an actual specimen 

 collected by Sonnerat. Watt, Wild and Cultivated Cotton Plants 

 of the World (1907) 255, leaves the Rumphian name as a syn-
