ON SEEDLINGS 



Capparis sandwicMana, DC. (fig. 182). 



Fruit stipitate, globose or cylindrical, baccate, many -seeded, 

 indehiscent. 



Seed reniform, slightly flattened, embedded in pulp, with very 

 unequal ends the smaller containing the radicle, the larger the

 section of seed, x 8 : B, R, B, radicle ; P, endosperm. C, longitudinal sec-

cotyledons ; testa black, smooth, crustaceous ; inner coat membra- 

 nous ; hilum in the basal notch. 



Endosperm forming a thin layer surrounding the embryo. 



Embryo large, spirally coiled, colourless ; cotyledons oblong, 

 each separately conduplicate, and then the double fold coiled spir- 

 ally, one each side of the seed with its back to the endosperm, and 

 both its edges lying in the centre of the seed and abutting against 

 the edges of the other cotyledon ; radicle long, cylindrical, obtuse, 

 incumbent, and forming a complete coil round the cotyledons and 

 along the periphery of the seed. 



Capparis, sp. (fig. 183). 



Hypocotyl woody, erect, compressed, tapering upwards, glabrous, 

 glaucous-green, 2-8 cm. long. 



Cotyledons large, foliaceous, ovate, obtuse, alternately incurvi- 

 nerved and reticulate, glabrous, deep green and convex above, shal- 

 lowly concave and scarcely paler beneath, shortly petiolate ; lamina 

 2-85 cm. long, T7 cm. broad; petiole 1-5 mm. long, persistent. 

 In the specimen sketched the halves of the cotyledons are of unequal 

 widths by 1 mm. The inequality of the one does not correspond to 

 that of the other. 



Stem woody, erect, terete, pubescent, pale green ; 1st internode 

 8'5 mm. long ; 2nd 4 mm. ; 3rd 1 mm. ; 4th 1*55 cm. ; 5th 1 cm. ; 

 6th 8 mm. ; 7th 1-15 cm. ; 8th 3'25 mm. First branch in axil of 

 a cotyledon.
