in the living flower and adnate to its lower edge and placed below it in. the 

 open laid flower. Dorsal petal ovate acute (15X6) anterior ones oblong 

 acute, adnate at the base. Tube 25 mm. Calyx half as long as the bracts 

 (18 X 8) blunt; ovary pubescent, capsula enclosed by the bract and bracteola, 

 rufous appressed-hairy, 18 mm. long, 15 broad, brownish-red. Valves red 

 internally. 



Leaves bright seagreen. Flower light yellow. Petals often pinkish. 



Distribution. In Java: This species is never cultivated. The citation 

 of RuMPH by Blume and the name "lampujang wangi" are wrong. 



It is a constant inhabitant of the teak forest of central and east-Java 

 vernac. name "lireh asse". 



In West-Java specimens were collected at Buitenzorg in bamboojungle, 

 numerous collectors; sund. name "e//o"'. Klapa Noegal, 200 M. (Backer 5867, 

 "pale yellow flower"); Tjiloa, Zandbaai, 10 M. in shrubby jungle (Backer 

 995); in central Java: Nusa kembangan ("light-forest", nat-coll), Randu- 

 blatung (Kds 42255 B, Ralshoven 1608), Kediri (Ralshoven). 



Outside of Java: Cambodge, Cochinchina, Gagnepain I.e. 



There may be distinguished a smaller, genuine, and a more robust 

 form (forma validior K. Sch). In the first the spikes, often terminating. foliate 

 stems 1,5 M. tall, are sessile between the somewhat approximated upper leaves, 

 with a rather small number of bracts; in the latter the scape of the lateral spikes 

 is 300—500 mm. to 1 meter long, the spike fusiform-ovate, 75 X 25—90 X 45, 

 with very densely imbricate bracts. Here the staminodes though small were 

 very obvious, white, facing the labellum and adnate to its basal edges. 



The leafstems here are sometimes 2 M. long, the leaves reach a length 

 of 450X38. The scapes often bear short leaves. 



10. Zingiber leptostachyum Val. le. bog. t. 275 (1908). 



This species has a superficial resemblance to Z. gracile. Jack, but it 

 differs manifestly by the shape of the labellum which is entire broadly 

 ovate, with very short rounded sidelobes (adnate staminodes). PI. 15 f. 21 

 In Z. gracile, according to Ridley, the lip is lanceolate, acute and deeply 

 bifid, while the sidelobes are oblong and 12 mm. long. 



It is also curious by the absolute wanting of pubescence. In a living 

 state the habit is rather different from other species by the short bright 

 green leaves (180 — 200X60 — 65), much more reminding a Globba than 

 a Zingiber. By the same characteristic and by the shape of the leaves it 

 differs from Z. stenostachys K. Sch. from Borneo. 



Distribution: Borneo centralis: NiEUWENHUis sine no.
