Leaf-segments glaucous on the underside. 

 Stem stout towards the base. Stamens 6 to 14 1. A. Alexandris. 



Stem much enlarged at the base, the rings forming steps at the base. 

 Doubtful if distinct from the above 2. A. Beatiicce. 



Leaf-segments green on both sides.

1. iL. iLlexandrse (after Princess Alexandra), Wendl. and Dnule, in 

 Linnea xxxix. 212. " Borum-bru," Cairns, Nugent. " Ko-pangara," Tully 

 Eiver, Roth. A tall palm, the stem attaining 70 to 80ft., enlarged towards the 

 base. Leaves several feet long, the rhachie very broad and thick, glabrous or 

 slightly scurfy, the segments numerous, the longer ones IJft. long, ^ to lin. 

 broad, acuminate and entire or slightly notched, green above, ashy-glaucous or 

 Tvhite underneath. Spatha l^ft. long. Panicle when open above 1ft. long and 

 ibroad ; much branched, the rhaohia more or less angular and flexuose, the 

 notches scarcely immersed. Male perianth, 2 to 3 lines^long, the inner segments 

 very frequently oblique, pale-eoloured, smoother and more acute than in A. 

 Cunninghamii , the outer segments about 1 line long, slightly imbricate. Stamens 

 usually 9 to 10, but varying in the flowers examined from 6 to 14, the filaments 

 very short. Female perianth about 2 lines long, the segments all broad, and 

 «,bout equal in length. Fruit ovoid-globular, usually about 6 lines diameter. 

 Ovary and seed of the genus. ^ — Ptychosperma Alexandra, F. v. M. Fragm. v. 47, 

 213, t. 43 and 44, not good, the stem too slender, and in Fl. Austr. vii. 140.

2. A.m Beatricese (after the Princess Beatrice Mary Victoria Feodore), 

 F. V. M. in Chem. and Druggist 1882. Step Palm. Stem stout, much enlarged 

 at the base and there the rings formed by the scars of fallen leaves are unusually 

 prominent, substance of stem comparatively soft. Leaves large, rigid, more 

 ■erect than divergent, the rhachis straight, segments numerous, grey on the under- 

 side, apex pointed. Panicle moderately long, the branches flexuose. Male 

 iflowers in pairs with often a female between them. Stamens 8 to 12. Anthers 

 linear, longer than the filament. — Extract from F. v. M. I.e. 



Hab.: Mount Elliott, E. Fitzalan. 



There is nothing in the above to separate the plant from A. AUxandrce, F. v. M., and I have 

 never seen specimens.

 xxxix. 214. " Wal-garri," Cairns, Nugent; " Piccabeen," Moreton Bay, Watkins. 

 Stems cylindrical, usually from 60 to 70ft. high, not thick for the height. 

 Leaves 6 to 8 or more ft. long, segments rather numerous and fairly regular, 

 linear usually ending in long almost thread-like points but sometimes broad and
