PENANG, Porter. MALACCA? Maingay. 



Stem slender, a span high. Larger leaf membranous, 5-8 by 2-4^ in., base 

 rounded or cordate, petiole 1-1 in. ; smaller, |-1 in., recurved. Flowers numerous, 

 in. diam. Calyx-lobes small, broad, obtuse. Corolla-lobes lanceolate, equalling the 

 anthers. Stigma minute, capitate. The largest-leaved species of the genus. 



13. A. XLurzii, C. B. Clarke ; quite glabrous, leaves 2 only, larger sessile 

 broadly ovate obtuse or obtusely-acuminate, smaller (stipule ?) ovate, umbels 

 simple, bracts 4, anthers 5 free broadly oblong-obtuse dehiscing by their whole 

 length. A. unifolium, Kurz in Journ. As. Soc. 1877, ii. 131, not of Blume. 



MARTABAN ; at Moulmein, Parish ; Attran, Scott. 



Stem simple, 3 in., forked, in one specimen stout, succulent. Leaves membranous, 

 large, 3^-5 by 2^-3 in., base rounded, smaller, ^ in., obtuse. Umbel 4-8-fld ; bracts 

 almost orbicular," equal. Flowers ^ in. diam. Calyx-teeth very short, broad acute. 

 Corolla-lobes lanceolate, much longer than the anthers. Only three specimens seen. 



*** Stem prostrate with many subequal pairs of thick distichous leaves, 

 one of each pair very large, the other very small. Habit of Elatostemma, 

 anthers with long beaks. 



14. A. Elatostemma, Hook. f. ; stem umbel and leaves beneath fur- 

 furaceously tomentose, large leaf of each pair shortly petioled obovate-oblong 

 obtuse base contracted cordate, smaller sessile ovate-cordate, umbels few-fld 

 simple or compound, corolla-lobes lanceolate, anthers 6 coherent subulate pro- 

 duced into a long straight beak opening by pores. 



PENANG, Griffith. SINGAPORE, Lobb. 



Stem 6-8 in., prostrate, very robust, simple or branched, sometimes rooting at 

 the nodes. Leaves 6-8 pairs, larger 2-2 in., coriaceous ; nerves about 10 pair, united 

 by very stout reticulating nerves. Peduncle softly tomentose. Flowers f in. diam. 

 Calyx small, lobes triangular, acute. Stamens as long as the puberulous corolla- 

 lobes. This species singularly resembles an Elatostemma in habit. 



15. A. parvifolium, Benn. PL Jav. Rar. 96; stem hispid, large leaf of 

 each pair petioled elliptic-ovate acute with few scattered cellular hairs above, 

 glabrous beneath except the midrib, smaller sessile ovate, umbels few-fld., simple 

 pubescent, corolla-lobes lanceolate, anthers 5 coherent subulate produced into a 

 long straight beak. Miq. Fl. 2nd. Bat. ii. 165, t. 31 D. 



SINGAPORE, Lobb. DISTRIB. Java. 



Stem 4-8 in. slender, prostrate, simple or branched, rooting at the nodes. Leaves 

 thick and succulent, in 4-8 distant or approximate pairs; larger -! in., base 

 rounded or cordate and equally or unequally auric! ed; smaller in. ; nerves indis- 

 tinct. Flowers similar to those of A. Elatostemma, but beak of anthers shorter. 



16. A. ophirense, Maingay mss. ; stem robust sparsely hairy, leaves 

 coriaceous glabrous, larger of each pair subsessile oblanceolate or obovate 

 obtuse or acuminate obliquely auricled at the base, smaller obliquely ovate- 

 cordate sessile, umbels few-fld. 



MALACCA ; on Mt. Ophir, Maingay. 



Stem 8-10 in., ascending, nodose, copiously rooting at the base, succulent. Leaves 

 thick and succulent, in many pairs, larger 2-3 by |-l in., smaller -| in. Calyx- 

 lobes very broad, acute. Corolla and stamens not seen.
