Short description:
Description View of a mature individual from below. The distinctive crownshaft and canopy of pinnate leaves is clearly visible. Note the smooth trunk and rows of circular leaf scars Roystonea regia is a large palm which reaches a height of 20–30 metres (66–98 ft) tall, [ 3 ] (with heights up to 34.5 m (113 ft) reported) [ 4 ] and a stem diameter of about 47 centimetres (19 in). [ 3 ] (K. F. Connor reports a maximum stem diameter of 61 cm (24 in).) [ 4 ] The trunk is stout, very smooth and grey-white in colour with a characteristic bulge below a distinctive green crownshaft . [ 5 ] Trees have about 15 leaves which can be up to 4 m (13 ft) long. [ 3 ] The flowers are white with pinkish anthers. [ 5 ] The fruit are spheroid to ellipsoid in shape, 8.9–15 millimetres (0.35–0.59 in) long and 7–10.9 mm (0.28–0.43 in) wide. [ 3 ] They are green when immature, turning red and eventually purplish-black as they mature. [ 5 ] Root nodules containing Rhizobium bacteria have been found on R. regia trees in India . The presence of rhizobia -containing root nodules is usually associated with nitrogen fixation in legumes ; this was the first record of root nodules in a monocotyledonous tree. [ 6 ] Further evidence of nitrogen fixation was provided by the presence of nitrogenase (an enzyme used in nitrogen fixation) and leghaemoglobin , a compound which allows nitrogenase to function by reducing the oxygen concentration in the root nodule. [ 6 ] In addition to evidence of nitrogen fixation, the nodules were also found to be producing indole acetic acid , an important plant hormone . [ 7 ] [ 8 ]
