LYTHRARIEvE 551 



above, paler on the back and rounded, glandluar-hairy on the 

 margins of the channels, and slightly so all round at the base. 



First pair ovate, acute, small. 



Ultimate leaves ovate, acuminate, acute, or the upper lanceolate, 

 all tapering to the base, rather opaque green, paler beneath. 



Cuphea coccinea, DC. 



Hypocotyl similar to that of C. silenoides, 3-5 cm. long, light 

 green, colourless, or tinged with red. 



Cotyledons broadly obcordate, emarginate, petiolate, glabrous 

 except on the petioles, indistinctly trinerved. 



Stem erect, herbaceous, hairy ; 1st internode about 1 mm. in 

 diameter. 



First leaves as in C. silenoides, hairy, light green, very shortly 

 petiolate. 



Lythrum flexuosum, Lag. 



Primary root very long, slender, flexuose, fibrous. 



Hypocotyl terete, glabrous, red, 4-12 mm. long. 



Cotyledons oblong-oval, obtuse, cuneate at the base, petiolate, 

 often slightly constricted near the apex and hence appearing obso- 

 letely tridentate, glabrous, showing a midrib on the lower two 

 thirds of its length only, 5-8 mm. long including the petiole, 3- 

 4-5 mm. wide. 



Stem herbaceous, erect (in the seedling stage at least), quadran- 

 gular or somewhat four- winged, glabrous, reddish ; 1st internode 

 1-4*5 mm. long. 



Leaves simple, cauline, opposite in the seedling, exstipulate, 

 sessile, glabrous, with a distinct midrib, and a few lateral, ascending 

 indistinct nerves. 



First and second pairs oblong-ovate, obtuse, entire, sessile, with 

 their bases decurrent on the stem forming the wings. 



Punica Granatum, L. 



Fruit very large, globose, baccate, glabrous, somewhat roughened 

 on the exterior, many-celled, many-seeded, indehiscent, crowned 

 with the persistent tube and five- to seven-lobed lamina of the calyx 

 on which the numerous stamens are persistent ; exocarp subcrusta- 

 ceous, yellowish ; style persistent. 



Seeds very large, variously angled by mutual pressure, and tapered 

 more or less to a cuneate base, glabrous ; outer layer of testa resolved 

 into a deep mass of watery, reddish pulp ; inner layer coriaceous 

 or subcrustaceous when fresh, ultimately hard ; hilum and micro- 

 pyle contiguous, basal ; chalaza apical.
