Abstract: -This study was carried out with the objective of describing the aerial and underground organs of birdsfoot trefoil [Lotus corniculatus (São Gabriel and ARS-2620 cultivars)] and big trefoil [Lotus uliginosus (Maku cultivar)]. The plants were cultivated in pots and harvested at 150 and 210 days after sowing. Stems, leaves and roots were prepared in according to conventional anatomical techniques. The anatomical structures of L. corniculatus and L. uliginosus differed in terms of pith cell integrity, starch cont… Show more

“…The underground stem of this plant was described as a xylopodium by Wanderley et al (2003), although xylopodium are tuberized structures derived from the hypocotyl and primary root. The morphology and anatomy of the underground stem of T. micrantha, as described here, suggests that its classifi cation as being a sobol, to be more correct -a diffuse stem-like underground system growing horizontally below the soil surface (Appezzato-da- Glória 2003, Maroso et al 2009). …”

“…Both Lees et al (1993) and Brillouet and Escoute (2012) reported that condensed tannins were transparent and colorless in unstained plant material. Lees et al (1993) found similar localization of tannins alongside phloem fibers in the sainfoin leaf rachis, and Maroso et al (2009) found similar tannin localization in BFT stems harvested after 210 d of growth. The tannins found in BFT may be colored rather than transparent, considering the known variation in the chemical structure of tannins.…”

“…The tannins found in BFT may be colored rather than transparent, considering the known variation in the chemical structure of tannins. Lees et al (1993) found similar localization of tannins alongside phloem fibers in the sainfoin leaf rachis, and Maroso et al (2009) found similar tannin localization in BFT stems harvested after 210 d of growth. Staining with FeSO 4 and TBO indicated that the tannin content of BFT stems is minimal and does not increase with accumulation of stem dry matter as plants mature.…”
