44. Lxxv. EUBUCE^. (J. D. Hooker.) \_Argostemma, 



7. A.. Parisbll, Sook.f. ; quite glabrous, leaves sessile in. whorls of 6 or 

 -6 or oftener in several superimposed pairs elliptic-lanceolate acuminate, umbels 

 branched terminal, calyx-teeth very short, anthers 5 free linear-lanceolate 

 straight obtuse opening by pores. 



Maetaban ; hills behind Moulmein, Parish, 



Similar in many respects to A. verticillatum, and, like it, quite glabrous ; but the 

 leaves are far more numerous, usually in approximate pairs, the corolla lobes longer 

 and very acute, the anthers much longer and obtuse. 



8. A. pumilum, Senn. PL Jav. Rar. 95; glabrous, leaves sessile about 

 10 almost v^horled lanceolate tip rounded lowest obovate, umbels very shortly 

 peduncled irregularly few-flowered, calyx-teeth broad obtuse, coroUsr-lobes long 

 subacute, anthers 5 free oblong opening by slits throughout then- length. A. 

 verticillatum. Wall. Cat. 8394 B., chiefly ; Siem in Fl. Trop. Africa, iii. 44. 



Khasia Mts., alt. 0-2000 ft., Be Siha, &c.— Distrib. "W. trop. Africa. 



A very small rather rigid species, 1-lJ in. high ; stem stiff. Leaves 1— li in., 

 more coriaceous than usual in the genus. Umbels smaller than the leaves, few-fld. 

 Flowers ^ in. diam. — ^The West African specimen from Mt. Sierra del Crystal (on the 

 upper G-aboon river) differs only in the anthers opening towards the summit. 



9. A. Iiobbii, Hodk.f. ; very slender, quite glabrous, leaves in numerous 

 superposed whorls of 4-6, of which 1 is much the longest linear-lanceolate sub- 

 acute, umbels axillary and terminal, pedicels slender divaricate, calyx-teeth short, 

 ■coroUa^lobes long, anthers 5 free linear-lanceolate curved with minute pores. 



Maktaban ; at Moulmein on limestone rocks, Lohh, Parish. 



Stem succulent, 4-6 in. Leaves in about 5-8 equidistant whorls, the long ones 

 1-1^ in., curved upwards, the short ones ^J in. Umbels branched from the base, or 

 peduncles forked. Flowers J in. diam. Calyx very small. Anthers not conniving. 

 Stigma minute. 



10. A. rostratum, Wall, in JRo.vb. Fl. Ind., ed. Carey Sf Wall. ii. 326 ; 

 Cat. 8395 ; quite glabrous, leaves whorled or in superimposed paii-a linear or 



-elliptic-lanceolate acuminate with often bulbiferous axils, umbels small solitary 

 simple or compound, corolla-lobes caudate-acuminate, anthers 5 coherent ob- 

 long with long slender beaks opening by pores. Benn. PI. Jav. Rar. 95. 



Khasia Mts., alt. 3-5000 ft.. Be Silva, &c. 



Very variable indeed in stature and foliage. Stem 3-10 in., slender or robust. 

 Leaves, the larger on each plant 1^-8 in., membranous, sessile or shortly petioled. 

 Umbels very various, few-fld. Pedmicles 1-3 in. Flowers ^ in. diam, Calyx small, 

 lobes short broad. Anthers very large for the size of the flowers, erect ; straight beaks 

 -as long as the cells. — The beaked anthers distinguish this from all allied species. The 

 bulbiferous specimens have smaller leaves and long capillary runners ; they often 

 ■somewhat resemble A. Lobbii. 



** Stem vrith a terminal pair of leaves, one very lai-ge, the other very 

 small, and sometimes one or more pairs of very small leaves lower down. 



11. A. buxnUe, Wall, in Benn. PI. Jav. Rar. 94; Cat. 8391; leaves^ 

 glabrous, uppermost pair of a very large ovate-lanceolate acuminate and a very ' 

 small ovate one, lower pairs few or solitary very small ovate subequal, umbels 

 solitary puberulous, bracts large, corolla-lobes lanceolate, anthers 4 linear- 

 subulate straight free obtuse opening by pores. 



Khasia Mts. ; Mahadeb, Griffith ; Churra, J. D. H. ^ T. T. Penang, Jack. 



Very variable in size. Stem 1-2 in., very short in comparison with the large leaf, 

 which is 2-5 in. long, sessile, membranous, the smaller leaf is ovate, i-i in. long. 

 Umbels 3-many-fld ; bracts ovate or orbicular. Anthers more than half the length 

 of the corolla-lobes. Stigma minutely capitate.
