■^'liorled, and wlien under water cut up into numerous capillary segments or 

 lobes; the upper ones sometimes, or very rarely nearly all, undivided, sessile, 

 linear or lanceolate and slightly toothed, all under 1 in. long and usually 

 about 1^ in. Pedicels in the upper axils longer than the cnlyx and usually 

 exceeding the leaves. Bracteoles small. Calyx usually under 2 lines long 

 at the time of flowering, the segments lanceolatCj acuminate, broad at the 

 base especially after tlovvering, membranous and 1 -nerved. Corolla blue, 

 with the centre yellow inside, about 5 or 6 lines long, the tube exceeding the 

 calyx, the lips broad and shorter than the tube, the upper one shortly 2-lohea. 

 Anthers cohering in pairs. Capsule broad and obtuse. — Benth, in I>C.

The species is widely dispersed over tropical Asia and Africa. The flowers are variously 

 described by Australian collectors as yellow pink or red. 



2. L. punctata, Blume ; Benth. in DC. Prod. x. 388. Stems ascend- 

 ing or erect, usually taller and stouter tlian in L. gratioloides, often above I 

 ft. high, the whole plant glabrous. Leaves opposite or rarely in whorls of 3, 

 sessile and stem-clasping, olilong.lanceolate, minutely serrate, 1 to H or 

 even 2 in. long, the upper ones smaller, the larger ones sometimes rugose. 

 Flowers violet-blue, 7 to 8 lines long, on pedicels scarcely shorter than the 

 floral leaves, tlie upper ones sometimes forming a very loose leafy raceme. 

 Calyx-segments lanceolate, subulate-acuminate, often above 3 lines long, 

 striate with 5 to 7 prominent nerves. Corolla-lips shorter than the tube, the 

 upper one very broad and refuse but scarcely lobed. Anthers cohermg i" 

 pairs. Capsule oblong, shorter than the calyx.

 Indian Archipelago, also in Ceylon. 



3. L. hirsuta, Bt-nth. in DC. Prod. x. 888. Very nearly allied to L 

 pmdcda, with the same undivided leaves, striate calvx, and rather Inrge blue- 

 violet corolla ; but it is usually a smaller plant, the'leaves more frequently m 

 -whorls of 3, the pedicels shorter, and the stems, pedicels, and calyx abva}=, 

 and usually the leaves also, pubescent or hirsute. 



N. Atistralia. Arnlicm's Laud, F. Mueller. The precise station uncertain, as J i» 

 labels of this and Z. gratioloides have been mixed both in the Mnelleriau and m i" 

 Hookerian herbaria. The species has au extensive range in tropical Asia. 



4. L. serrata^ G«//c^/c7i. in Frnjc. Tov. 418. t. 57. Decumbent or 

 erect not much branched and quite glabrous, the stems usually slender i to 

 1 tt. long. Leaves ovate oblong or lanceolate, obtuse, obtusely-serrulnte, tiie 

 lower ones contracted at the base, the upper ones with a broader base, aU 

 stem-claspmg, under 1 in. long. Flowers closely sessile in the upper as .J 

 mostly distant but the upper ones sometimes crowded into a short teriiuna 

 leafy spike. Bracteoles small, linear. Calvx thinner than in the tuo pi 

 ceding species, not exceeding 2 lines, tbe segments subulate-acuniinat ,
