- Diagnosis
- Small, oval, orthotropous, dicotyledonous, unitegmic seed measuring 2.43 mm in length and 1.25 mm in width. Seed coat differentiated into Testa and Tegmen measuring about 133 µm in thickness. Testa is single celled, undifferentiated, 5-6 µm in thickness. Tegmenis single layered, compactly arranged sclerenchymatous cells measuring 20-30 µm in thickness. The gap is observed between testa and tegmen measures about 32-40 µm in thickness. Nuclear endosperm is 30-31 µm at the tapering ends and 12-20 µm at the broader region. Embryo is thin walled, parenchymatous, single celled, large in size measuring 0.91 mm-1.92 mm in length and 30 µm in diameter. Embryo length is less than ¾ of the seed length and width is about ¼ of seed width. Hypocotyl region is differentiated into radical at outside and plumule at inside of the seed cavity. Hypocotyl region was about 140 µm in length and 230 µm width. Cells of radicle are 15-25 µm in size. Wall of the embryo is 7 -20 µm in thickness. All the features described above made it possible to assign it to a family of its close resemblance. On the basis of the seed coat characters it appears that the seed belonged to the dicotyledonous family. Exostome and chalazal end at the same plane indicating orthotropous position.
