adnate only 25 mm. the free part 35 mm. long. Of an other spike consisting 

 . of 28 bracts the mean size of the 14 lowest bracts was 16 — 18 (free 

 part) + 22 — 23 (pouch) X 25 — 30. The intermedial bracts measured 32 

 (fr. p) + 30 (pouch) X 30, 30 + 26 X 27 and 29 + 20 X 28. The tallest 

 of the coma-bracts measured 70 X 25. 



The 3 or 4 superior coma-bracts are dark purple mostly 577 and 578 

 but varying between 576 and 583, the following are white or light green at 

 thé base, striped in the middle. The intermedial bracts (bract No. 23 from the 

 base) are green and violet striped down the middle, violet at the top. The floral 

 bracts are light green with a violet top, the undermost almost wholly green. 



All bracts are puberulous and shortly ciliolated. The flower is rather 

 large (50 — 60 mm.) and protrudes a good deal above the bracts. The 

 bracteole is 20 — 25 mm. long, or in another spike 28 — 30. It is white 

 with, a pink top. The calyx is 9—10 mm. long subtruncate with three very 

 small ciliate teeth and with a short fissure. 



Corolla-tube 18, faux 18—22, Labellum 18 X18 with a narrowed base. 

 Stamd 16X10. broad, f labellate, fi lam. 3. 5 X 4, anther (without the spurs) 5 mm. 

 Spurs feebly curved, thin, 3 mm. Dorsal corolla-lobe 15 X 14, lateral 12 X 12. 



The whole corolla is pale orange-coloured (171 —0.171), the medial band 

 of the labellum 151. The coroll-lobes very pale pink (0596), the bud pink. 



Distribution and native names. This species grows spontaneous 

 in the teak forests of all parts of Java. I also received specimens of the Yang 

 .plateau from Dr. Jeswiet and Mr. Backer collected it on mt Wilis at 300 M. 

 (Backer 1 1348). According to information taken by Mr. Ralshoven the rhizome 

 is not used by the natives in the central parts of Java. In West-Java it occurs 

 sometimes at the passer but without a proper name; sometimes it was sold 

 by the name "tis" or "tinggang' (just as C. purpurascens) (Heyne c. 35). In 

 east-Java (Pasuruan) the less clever expert natives called it "tema labak" 

 {= Curcuma xanthorhiza) and from Tjabak (Rembang) I received it with the 

 name temu kètèk ("monkey turmeric"). Also from Randublatung (K. 1645, 

 no native name). It is a beautiful species easily recognized by the broad 

 dark purple coma, the tall flower stalks, the large orange coloured flowers, 

 the tallest flowers of any Curcuma of Java, the peculiar form of the lower 

 flower-bracts which are adnate above the middle with expanding, narrowed, 

 very blunt tips. It has some resemblance to C. petiolata and would be 

 placed by Baker in the subgenus Hitcheniopsis. By the flower however it 

 is a true Eu-curcuma. 



Outside Java the species is still unknown.
