different as to the length, for it is 20-30mm. broad at the midst and extends 

 in the adult leaves as a narrow strap along the midrib till near the base, 

 while in the former species it always ends abruptly beneath the middle. Here as 

 in the other species having purple stained leaves the cloud diminishes and 

 obliterates at the end of the rainy season and in infavorable circumstances. The 

 scape and spike are as in C. aeruginosa but the shape and colouring of the 

 bracts is somehat different; the coma bracts are longer and narrower (f. e. 

 80X30) and much more acute than in C. aeruginosa where they have a 

 rounded mucronate top. Further the coma bracts are white at the lower half 

 and redpurple coloured at the top. The flowering bracts are circ 50 mm long, 

 (The free part elliptic acute 30X16). Intermedial bracts 65, free part oblong 

 ovate, 45 X 23 ; in an other flower 55, freepart 40 X 25. The bractlets are rather 

 long, longer than the corolla-tube (30X20). The flowers are longer, 40-50, 

 and differ from the former by the longer faux (14X25) and especially by 

 the staminodes which are obovate elliptic longer and broader than in the 

 former and obtuse not truncate. 



They are 13-15,5 in the midst, only 10 mm long at the innerside Fil. 

 4x4. The anther has rather long curved spurs, which differ obviously from 

 the short straight spurs of the former. The petals are red, the entire label- 

 lum deep yellow.

This species is common in Java, cultivated and spontaneous. It belongs 

 to the habitual flora of the teak forests and was found on the mt Yang by 

 Jeswiet and Backer at 500 M. The native name is "Teniu itam" juist as 

 that of C. ae/uginosa, but from Tomo (Soemedang, Western Java) it was 

 sent by the name "temu santen", while the name "temu itam" was reserved 

 by the expert natives for C. aeruginosa Roxb. A specimen collected by 

 Backer (17628) at Tjiletoek at 100 m. belongs probably to this specis. If 

 comparing the descriptions given here there will be litle doubt that the two 

 species though nearly allied are different in details in all parts. Both belong 

 to a group of species described by Roxburgh and Roscoe, having in common 

 the presence of a blue colour in the rhizomes, a red coma and yellow 

 flowers with dark rose somewhat coriaceous petals. These are C. caesia, 

 C. aeruginosa, C. amarissima, C. phaeocaulis and probably also C./irr/z^mea. 

 The latter is not mentioned in the description as having blue coloured 

 rhizomes; but in Roscoe's picture the pleroma is distinctly blue tinged, and 

 the flowers resemble very much those of the other species here named. 

 These species may be distinguished bij the following survey: 

 C. aeruginosa Roxb. Stem green. Bulbs and rhizomes internally 

 blue or blue greenish tinged or aeruginous. Adult leaves with a broad dark 

 or pale purple cloud along the midrib above the^middle, green belowthe middle. 

 Coma bracts purple almost to the base. Habitat: Burma and Malaya, Java:
