Dicot and Monocot Leaves

Dicot and Monocot Leaves Angiosperm leaves have many shapes and sizes (see Photographic Atlas of Plant Anatomy by Curtis, Lersten and Nowak, Leaf External Morphology -http://botweb.uwsp.edu/anatomy/ ).

SEED DEVELOPMENT IN ASTRAGALUS CEMERINUS AND A. RUSCIFOLIUS

The overall morphology and development of the ovule in A. cemerinus and A. ruscifolius reaffirm earlier observations on the subfamily Papilionoideae (Prakash, 1987) and on other species of Astragalus (Lersten, 1983; Riahi et al., 2003).

Ultrastructure of secretory and senescence phase in colleters ...

426 E. C. miguel et al. : ultrastructure and senescence of Bathysa colleters Rubiaceae colleters are secretory structures associated to the stipule. they can occur at adaxial surface or at margins; and it is possible to notice at calyx, close to trichomes (majumdar & pal 1958, horner & lersten 1968, lersten ...

Embryogenesis in Angiosperms: Development of the Suspensor

Wardlaw, 1955; Lersten, 1983). In most cases, the suspensor functions early in embryogenesis and then degenerates dur- ing later stages of development and is not present in the mature

FabaceaeCPea family

Rugenstein and Lersten (1981) report the presence of stomata on the seeds and pods of purple bauhinias and orchidtrees. In general, bauhinia seeds contain high amounts of linoleic and oleic fatty acids and low amounts of myristic and linolenic fatty acids (Balogun and Fetuga 1985; Ramasastri and ...

Hymenachne

NOTE : May be confused with the native Sacciolepis striata (L.) Nash, American cupscale, which has a similar inflorescence, or with other marsh grasses of similar form, but Hymenachne stems distinctive in containing white pith (most grass stems are hollow) (Pohl and Lersten 1975).
