3. N. Brownii (after Dr. R. Brown), Bail. The small blue water lily of our 

 tropics. Leaves smaller but much the shape of those of iV. rjiriantea, margins 

 slightly repand, entire, texture thin and the reticulation on the underside never 

 raised. Flowers blue, 4 or 5in. diameter. Sepals spotted and as well as the 

 petals often somewhat acute. Stamens numerous, filaments flattened. Anthers 

 with very short or no terminal appendage. From note in Flora Australiensis 

 i. 61, it seems that Mr. Bentham concurred with some other botanists in con- 

 sidering this northern plant only a form of N. ciUjantea. Baron Mueller gave it 

 in his publications as -V. stellata, and the author of the Flora Australiensis says 

 that Robert Brown was in favour of placing it under this name. In the synopsis 

 of the Queensland Flora I recorded it as N. cmrulea, considering it agreeing best 

 with the species so named, which at the present time is merged by botanists into 

 N. stellata. It will be seen to differ from N. stellata in the want of prominent 

 anther-appendages and from ^V. gigantea in the absence of the prominent raised 

 reticulation on the underside of the leaves. Therefore it is here given as a 

 species bearing the name of the botanist who probably first recorded it. 



Hab.: Waters of the northern parts of the colony. 



4. UT. tetragona (four-angled), (n'oir/i. A small plant ^yith oblong- orbicular 

 leaves 1 to Sin. long, the basal-lobes acute, sometimes spreading ; petioles 

 smooth, slender. Flowers white or more or less stained with purple. Sepals 

 lanceolate, about lin. long, the petals somewhat longer. Anther without 

 appendages, but the cells not extending to the end of the obtuse apex. Seeds 

 somewhat flask-shaped, bearing many longitudinal ciliate ribs. — N. pijgmaa, Ait. 

 Hook. Fl. Brit. Ind. i. 115 ; X. minima, Bail. Syn. Ql. Flora 10. 



Hab.: Still shallow waters off the Barron Kiver. The rootstock not preserved for examination ; 

 in the Indian specimens said to be woolly, with soft black hairs. 



5. W. flava (yellow), Leit. Hook, in Bat. Mag. t. 6917. Rhizome erect, 7 or 

 more inches long and often more than l^^in. thick, having the appearance of being 

 prominently tuberculous from the swelled persistent bases of fallen leaves ; from 

 near the crown are emitted long white stout fleshy running stems, which form 

 fresh plants at distant intervals. Leaves orbicular, elliptic or broadly oblong, 

 6in. or more in diameter, on pale-green petioles ; upper side deep-green, the under 

 side more or less of a purplish colour, margins entire, slightly undulate, sinus 

 narrow, basal lobes subacute, the nerves and veins not prominent on either side. 

 Flowers pale yellow, about 4in. in diameter, each bloom remaining perfect for 

 several days. Sepals lanceolate, more or less tinged on the back with purplish- 

 red. Petals similar in shape but smaller than the sepals, the inner ones smaller 

 than the outer, pale-yellow on both sides. Stamens numerous, sub-erect, outer 

 filaments much the longest and dilated at the centre, inner filaments linear. 

 Anthers linear, connective hardly produced, tips rounded, cells parallel. Stig- 

 matic-rays 8, short, broad, obtuse incurved, inappendiculate. Berry globose, 

 about lin. in diameter, almost white, marked with short transverse scars. Seeds 

 globose-oval, 3 lines long, silky- villous. 



Besides Sir J. D. Hooker's account in Bot. Mag. I.e., there are two accounts with figures in 

 The Garden xxiii. and xxvii. 



Hab.: This beautiful Florida water-lily was introduced some 14 or 15 years ago (without name) 

 by the Queensland Acclimatisation Society ; soon after which it was planted out in one of the 

 ponds at Bowen Park. It soon took possession of the pond, and is now said to have become 

 quite naturalised in the still waters about Wellington Point. — Colw Kifford. According to Hook. 

 I.e., this spfeciefe was first figured in an American work on Ornithology about the year 18.S2.' The 

 present desoi'iption refers to the plants growing in Queensland waters.
