and more spreading than the lower ones. They are very finely villose on 

 the surface. The 4 highest are not fully developed, they are much narrower 

 than the others and sterile. In a large inflorescence the coma-leaves attain 

 90X40, the bracteole 25. All coma-bracts are violet, between 551 and 576. 

 The ovary is slightly hairy, 4 mm. long, the calyx 9 mm. long, colourless 

 with 3 light red toothlets. The corolla is 40 mm. long, of which 20 mm. 

 comes on the tube. The petals and faux are light-red, between 021 and 

 21. The lip is yellow, (241—246), the mid-lobule apparently entire, darker 

 yellow (176); stamina whitish. The lowest light-green bracts are as long 

 as the flower, 60—55, bluntly rounded with an acute top. They nearly 

 protrude from the bract and the dark-yellow top of the lip is less 

 protruding than in C. purpurascens, Mangga etc. The structure of the petals 

 is firm. The flower is large and the tube 20—24 mm. long, and upwards 

 not much dilated, but the in proportion short faux is abruptly campanulately- 

 enlarged above the mouth of the tube. The proportion of the tube-length 

 to the border-length is 4 to 5, this being in C. Zedoaria nearly as 1—2. 

 Particulars of the flower are still the broad thick ring of hair, the broad 

 downward a little narrowed lip, (18X^8) with broad side-lobes and a 

 slightly protruding mid-lobe. The staminodes are broad (14XU) with a 

 very flabelliform wrinkle in the middle, quite hidden in the short dorsal 

 lobe, but slightly bent inward. The bracteole is somewhat longer than the 

 tube (25 15). The anther is short and broad and has a thick outer side- 

 wall of the loculi, the spurs are about as long as the loculi and not much 

 spreading laterally. Under a good glass (8X10) it is to be seen that the 

 whole dorsal side is covered with fine glandular hairs. 

 Distribution and native names. 



The species described here under the name of C. xanthorhiza, RoxB. 

 is cultivated throughout Java under the constant malay and Javanese name 

 "temoe lawak", and in the Western-Java under the name "koneng gedeh". 



As I have not seen an authentic specimen of Roxburgh and as his 

 description includes only a few characteristics, the determination is not quite 

 certain. The characteristics given by Roxburgh are: Lateral inflorescence, 

 deep-yellow rhizomes and root-tubers (the latter is a fact that very seldom 

 occurs and was considered as sufficient for determination by Roxburgh), 

 a purple cloud on both sides along the whole midrib, and red petals. 

 Schumann gives still some characteristics not occurring in the species, 

 treated here, viz. the leaves should be shortly pubescent at the backside the 

 bracts greenish-yellow and the coroll-lobes should have a red edge. This red 

 edge of the petals however is a quite incorrect translation of the expression 

 of Roxburgh's "outer border of the corolla red"; for, with "outer border". 

 Roxburgh means, as is known in all his descriptions, the petals themselves, 

 in distinction from "the inner border", i.e.=lip and staminodes. The petals
