PONTEDERIACEAE— STEMONACEAE

CYANOTIS Don 



CYAN OTIS MOLUCCANA (Roxb.) Merr. in Philip. Journ. Sci. 2 (1907) 

 Bot. 266. 



Commelina moluccana Roxb. Fl. Ind. ed. 2, 1 (1832) 172. 

 Commelina uniflora Hassk. Commel. Ind. (1870) 104. 

 Arundinella III aquatica Rumph. Herb. Amb. 6: 24? 



This reduction of Arundinella III aquatica is merely a sugges- 

 tion. However, it may be merely Commelina obtusifolia Vahl, 

 as suggested by Hasskarl, Neue Schlussel (1866) 155, which 

 is supposed to be a synonym of Commelina nudiflora Linn. 



FLOSCOPA Loureiro 



FLOSCOPA SCAN DENS Lour. Fl. Cochinch. (1790) 193. 

 Arundinella V Rumph. Herb. Amb. 6: 25. 

 Amboina, in sago swamps near the town of Amboina, Robinson PL 

 Rumph. Amb. 409, July, 1913, locally known as kangkong ayer. 



The reduction follows Hasskarl, Neue Schlussel (1866) 165, 

 who suggests Floscopa paniculata Hassk. (=F. scandens Lour.), 

 as the proper disposition of Arundinella V of Rumphius. 



PONTEDERIACEAE 



MONOCHORIA Presl 



MONOCHORIA VAGINALIS (Burm. f.) Presl Rel. Haenk. 1 (1827) 128. 



Pontederia vaginalis Burm. f. Fl. Ind. (1768) 80. 



Olus palustre Rumph. Herb. Amb. 6: 178, t. 75, f. 1. 

 Amboina, in grassy pools near the town of Amboina, Robinson PI. 

 Rumph. Amb. 225, July 25, 1913. 



Olus palustre was first reduced to Monochoria (Pontederia) 

 vaginalis by Linnaeus, Mant. 2 (1771) 222, this certainly being 

 the correct disposition of it. 



Olus palustre femina Rumph., 1. c. 178, is probably merely a form 

 of Monochoria vaginalis Presl, approaching M. vaginalis var. 

 plantaginea Solms, and possibly represented by PI. Rumph. Amb. 

 22U from Amboina, August 23, 1913. Hasskarl, Neue Schlussel 

 (1866) 180, suggests that Olus palustre femina is Monochoria 

 sagittata Kunth=M. hastata Presl, but the description hardly 

 warrants this disposition of it. 



STEMONACEAE 



STEM ON A Loureiro 

 STEM ON A TUBEROSA Lour. Fl. Cochinch. (1790) 404. 



Roxburghia gloriosoides Roxb. PI. Coromand. 1 (1795) 29, t. 82. 

 Ubium polypoides I album Rumph. Herb. Amb. 5: 364, t. 129. 

 Amboina, Paso, Robinson PI. Rumph. Amb. 295, October 29, 1913, climb- 

 ing over trees along the seashore.
