Ad LXXV. RUBIACEX. (J. D. Hooker.) [ Argostemma, 
7. A. Parishii, Hook. f.; quite glabrous, leaves sessile in whorls of 5 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. 
ManrAnBAN ; 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 aeute, the anthers much longer and obtuse. 
8. A. pumilum, Benn. Pl. Jav. Rar. 95; glabrous, leaves sessile about 
10 almost whorled lanceolate tip rounded lowest obovate, umbels very shortly 
peduncled irregularly few-flowered, calyx-teeth broad obtuse, corolla-lobes long 
subacute, anthers 5 free oblong opening by slits throughout their length. A. 
verticillatum, Wall. Cat. 8304 B., chiefly ; Hiern in Fl. Trop. Africa, iii, 44. 
Kuasia Mrs., alt. 0-2000 ft., De Siha, &ce.—Disrrm. W. trop. Africa. 
A very small rather rigid species, 1-1} in. high; stem stiff. Leaves 1-1} in., 
more coriaceous than usual in the genus. Umbels smaller than the leaves, few-fid, 
Flowers 4 in. diam.—The West African specimen from Mt. Sierra del Crystal (on the 
upper Gaboon river) differs only in the anthers opening towards the summit. 
9. A. Lobbii, Hook. f.; very slender, quite glabrous, leaves in numerous 
superposed whorls of 4-6, of which 1 is nid the longest linear-lanceolate sub- 
acute, umbels axillary and terminal, pedicels slender divaricate, calyx-teeth short, 
corolla-lobes long, anthers 5 free linear-lanceolate curved with minute pores. 
ManTABAN ; at Moulmein on limestone rocks, Lobb, Parish. 
Stem succulent, 4-6 in. Leaves in about 5-8 equidistant whorls, the long ones 
1-13 in., curved upwards, the short ones l-lin.  Ujabels branched from the base. or 
peduncles forked. Flowers lin. diam. Calyx very small Anthers not conniving. 
Stigma minute. , 
10. A. rostratum, Wall. in Roxb. FL Ind., ed. Carey & Wail. ii. 826 ; 
Cat. 8395; quite glabrous, leaves whorled or in superimposed pairs 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. Pl. Jav. Rar. 95. 
Kuasa Mrs., alt, 3-5000 ft., De Silva, &c. 
Very variable indeed in stature and foliage. Stem 3-10 in., slender or rfbust. 
Leaves, the larger on each plant 13-8 in., membranous, sessile or shortly petioled. 
Umbels very various, few-fld. Peduncles 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.—Tho 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 with a terminal pair of leaves, one very large, the other very 
small, and sometimes one or more pairs of very small leaves lower down. 
ll. A. humile, Wall. in Benn. Pl. Jav. Rar. 94; Cat. 8391; leqves 
glabrous, uppermost pair of a very large ovate-lanceolate acuminate and a es 
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.

Kuasta Mrs.; Mahadeb, Griffith; Churra, J. D. H. d T. T. Pzwawa, Jack. , 
Very variable in size. Stem 1-2 in., very short in comparison with the large leaf, 
whieh is 2-5 in. long, sessile, membranous, the smaller leaf is ovate, 4—4 in. long. 
Umbels 3-many-fld; bracts ovate or orbicular. Anthers more than half the length 
of the eorolla-lobes. Stigma minutely capitate.
