 nodes subglobose. Stamen-filament linear, the connective prolonged, 

 tridentate. Anther 2 mm long.

I have seen nothing corresponding to this description, nor hivve I seen Presl's 

 figure quoted above. Schumann makes it to be an Alpinia of the section liintalua, 

 which includes this and the next species and a Bornean plant (from Bintulan, 

 whence the name) . It is pretty clear from the description that the two Philippine 

 plants are not Alpinias, but are probably Plagiostachys.

Stem fairly stout. Leaves linear-lanceolate, acuminate, caudate, 

 narrowed at the base, glabrous on both sides, 45 cm long, 8 cm wide; 

 petiole 4 cm long; ligule short, glabrous. Spike projected from a leaf- 

 sheath above the rhizome, cylindric, very dense, the base laxer, obtuse. 

 Bracts at the apex subcomose, 10 cm long, the peduncle with rather large 

 ovate bracts. Bracts clavate, apiculate, 12 mm long, obliquely truncate, 

 the apex only minutely pilose. Ovary glabrous. Calyx cylindric, 12 

 mm long, 3-toothed, glabrous. Corolla-tube 10 mm long, the upper 

 lobe cucullate, C mm long. Filament linear, 3 mm long, crestless. Lip 

 obovate, bilobed, 5 mm long.

I have seen no specimens answering to this description, which is translated from 

 Schumann. It can not be an Alpinia, and I think it is probably a Placiiostachi/s.

 (Elmeria Ridl. 1. c. 569, non Elmera Rydb. 1905.) 



Herbs with few or solitary stems of moderate height. Leaves lan- 

 ceolate or elliptic. Inflorescence a terminal capitulum. Bracts large, 

 ovate, persistent. Bracteoles utricular, with three acute lobes, ciliate at 

 the tip, the nerves of the bracts and bracteoles anastomosing. Calyx

 fleshy, adnate to the stamen. Anther quite entire or bifid, short. Sta- 

 minodes none. Stamen-filament broad, linear. Anther-cells linear, 

 pubescent, the crest small or none. Style short, slender, filiform. Cap-
