This species is named from the externally and internally, white, in the 

 center greenish-lemon tinged, rhizome, never met with in any other one of 

 this group. It belongs very near to C. brog by the green leaves pale flowers 

 and whitish bracts. Whether old stocks can reach the sarne dimensions is 

 still incertain. 



The young rhizome has a faint taste of mango or carrots. 



It was sent (only once) from the teak forests of Randublatung bearing 

 the fancy name of "Temu lawak" {—C. xanthorhiza, Roxb.) and cultivated. 

 Heyne 705. Flow. Nov. 1917. 



This species appears rather nearly related to C. amada, Roxb. (Fl. ind. 

 I 33) of which Roscoe (1830, t. 99) gives the following description: "Coma 

 rosecoloured, corolla pale yellow or strawcoloured, lip obscurely threelobed, 

 yellow. Spike central, plant entirely green. "Bulb a conical tuber; palmate 

 tubers at the base, thick fleshy, fingered, inwardly pale yellow. Pendulous 

 tubers farinaceous pale. Fertile bracts pale green or strawcoloured." 



"A native of Bengal, known as "amada" or mango-ginger, because of 

 the peculiar smell of the rhizome which is used as a medicine." 



These species are thus different by the colour of the petals and of the 

 bracts. Moreover the rhizome of C. ochroleuca has only a very faint smell 

 of mango, and is not used medicinally in Java. It differs from C. broghy 

 the obtuse bracts of the spike. 



Curcuma soloensis. Val. n. sp. 



Herba metralis vel sesquimetralis. Bulbus et rhizoma fere precedentis, 

 elongata, rami sat longi falcati et clavati omnia extus juventute pure, demum 

 sordide, aurantiaca. Tuberi penduli intus grisei endodermate luteo. 



Folia modice petiolata, late lanceolato- et ovata-elliptica, basi subro- 

 tundata, apice sensim acuminata, crasse herbacea, inde a juventute plane 

 viridia. Ligula in utraque parte petioli basi auriculatim prominens ciliata et 

 cum vaginae margine hirtella. 



Inflorescentia cum pedunculo 300 — 750 mm. longa. Folium peduncu- 

 lare singulum vel dua, bracteiformia, externum bracteis ceteris duplo lon- 

 gius. Bracteae pallide virides, ovatae (cum pursa obovatae) acutiusculae, 

 marginibus paullum erectis incurvis pallide virides, patulae. Br. comae par- 

 tim roseae, ellipticae apice mutico. Bracteolae corollae tubum aequantes. 

 Calyx apice truncatus, mucronibus nuUis. Corolla pallide aurantiaca, labelli 

 parte mediana intense aurantiaca. Petala pallide rosea. Staminodia oblonga 

 obtusa medio plicata. 



The root-system is again much like that of C. piirpurasce(is. An old 

 tuber is 60X45 and internally dirty-orange (almost 181). The rhizomes 

 100X25 are sallow-orange-brown (181), a side-branch is 60 X 20; a side- 

 tuber 80X20. Young rhizomes are pure orange-yellow on the section (161).
