424 ON SEEDLINGS 



No. 8. Oblong, obtuse, subhastate, cuneate at the base and dis- 

 tantly serrate above the basal lobes. 



No. 9. Hastate, obtuse, cuneate and trinerved at the base. 

 Nos. 10-13. Similar, or slightly more serrate. 



Chenopodium viride, L. 



Hypocotyl thin, 2*5-3 cm. long, tinged with a deep red. 



Cotyledons oblong, obtuse, fleshy, petiolate, entire, mealy, dark 

 green tinged with red or purple beneath, indistinctly one-nerved. 



Stem light green, mealy ; primary internodes very short. 



First leaves entire, cauline, opposite, decussate, oblong-oval, ob- 

 tuse, with short petioles, mealy, light green above, tinged with red 

 beneath, pinnatinerved. 



Beta trigyna, W. et Kit. 



Ovule pendulous from a basal funicle, campylotropous ; micro- 

 pyle superior, or pointing a little to one side. 



Fruit a utricle, agglomerated in masses owing to the flowers 

 being sessile, enclosed in and even adnate to the hardened and 

 persistent perianth, sumranded by its five free persistent segments 

 of the perianth and the cup-like base of the connate stamens, the 

 filaments of which are free upwards, persistent, and folded over the 

 apex of the utricle which is one-celled, one-seeded and indehiscent. 



Seed subglobose, or somewhat angled or compressed, conforming 

 to the interior of the utricle, notched at the base or subreniform 

 and suspended from a basal funicle, glabrous, shining, black ; teg- 

 men rather thinner and paler coloured than the thin and subcrus- 

 taceous testa ; hilum, micropyle, and chalaza contiguous, basal and 

 superior ; raphe none. 



Endosperm forming a mass lying in the middle of the seed, 

 between the radicle and cotyledons, and also a thin layer between 

 the embryo and the testa, farinaceous and loose when dry, white. 



Embryo peripheral, comparatively large, much curved, colour- 

 less ; cotyledons oblong-linear, obtuse, entire, plano-convex, lying 

 in the narrow way of the seed with their edges to the floral axis, 

 longer than the radicle, and very little broader than its thickness, 

 much curved, sometimes twisted ; radicle thick, curved, tapered to 

 an obtuse point, embedded in a very thin layer of endosperm and 

 close to the micropyle. 



Beta vulgaris, Moq. 



Primary root tapering downwards, with a few fibrous lateral 

 rootlets, red.
