probably accounts for its having been overlooked by the Indian 

 botanists. 



J. suffruticosa (J. jissendocarpa Haines) may be described thus: — 

 A herb, simply branched or compound-branched, sometimes slightly 

 woody at the base, slender, 1 to 2 feet tall, quite glabrous ; branches 

 slender, winged. Leaves lanceolate, narrowed to the tip and base, 

 thin and membranous, '5 to 3 in. long, '25 to '5 in. wide ; petiole 

 slender, winged nearly to the base. Pedicel with ovary 5 in. long. 

 Sepals 4, very narrow lanceolate-acuminate, 4 in. long. Corolla 

 shorter, yellow ; petals very small, 4 in. or less long, subrhomhoid, 

 base narrowed but notclawed, narrowed and blunt at tip. Stamens 8; 

 style cylindric ; stigma capitate. Fruit cylindric with persistent 

 sepals '75 in. long, 1 in. through. Seeds in upper part ellipsoid, 

 smooth, pale, in the middle larger and slightly corky, at base much 

 larger, oblong with a groove on one side, corky. 



Iiab. India, Purnea and Bengal (Haines) ; Malabar (Serb. Kew.); 

 Siam, Bangkok (Kerr 4041) ; Malay Peninsula, Singapore, very 

 common Kelantan, Glam Woods and Chaning. Penang (Curtis) ; 

 Christmas Isle one plant (possibly introduced accidentally from 

 Singapore) ; Philippines, Paragua (Merrill 797), Mindanao (1021), 

 Luzon (Cuming 055 and 1055, Loher 2166, 2167). 



J. tenella Burm. Fl. Ind. 103, pi. 34, fig. 2, Java, may possibly be 

 this, but it might be Ludwigia perennis L. The plant has the 

 habit of L. perennis and equally small flowers, but it has the stamens 

 of Jussicsa. According to description, J. fruticosa DC. Prodr. iii. 

 57, is probably J. suffruticosa ; it is a native of Cochin China. I 

 found a very succulent form of J. suffruticosa near the sea at 

 Calang, in Singapore, with a thick fleshy stem and broad elliptic, 

 long-petioled leaves 15 in. long, - 6 in. wide, the petiole "5 in. long ; 

 this seems to me a seashore form. 



3. Jussi^a ebecta L. Fl. Zeyl. 170; Sp. PI. 556, is based on 

 the " Herba vitiliginum " of Humph (Herb. Amboin. vi. p. 49, t. 21, 

 fig. 1), on which drawing and description Lamarck also based his 

 -/. angustifolia (Lam. Diet. iii. 331 ; 111. t. 280, fig. 3). This species 

 is also referred to J. suffruticosa by Hooker, Clarke, and King. 

 There is a drawing of what is clearly intended for this in Rheede's 

 Hort. Malab. ii. 97, t. 50, but Lamarck refers this to his J. villosa. 

 Linmeus (Sp. PI. 55(j) unfortunately added to his synonyms three 

 references to South American plants, and gives as habitat " in America 

 et forte in Virginia." J. JBlumeana DC. Prodr. iii. 55 and J. Jung- 

 huhnii Miq. Fl. Ind. Bat. i. 1, 627 from .Java seem from descrip- 

 tion to be J. erect a. 



J. erecta is often tall, up to 3 or 4 feet, but dwarf forms 

 occur. It is quite glabrous or may be sparsely hairy, especially on 

 the young parts. The stem is fairly stout, angled or slightly winged 

 and simply branched. Leaves lanceolate-acuminate, long-narrowed 

 at the base; nerves ascending, 14 pairs slightly elevate beneath; 

 midrib and nerves often more or less sparsely hairy, 2 to 4 in. long, 

 •25 to 1 in. wide. Ovary and pedicel '5 in. long. Sepals 4, ovate 

 acuminate, 4 2 to - 2 in. long, increasing in fruit to -3 in. lone- and 

 •12 in. wide; nerves prominent 3, hairy. Corolla 1 25 in. wide, bright
