OF MAEINE COASTS. 89 



stems, and erect flowering branches, 3 — 7 cm. high, glabrous, somewhat 

 yellowish; leaves small, thick, ovoid; flowers yellow. 



Common in Europe and temperate Asia. Not confined to coastal 

 sands, but frequently occurring there. 



Tillaea minima Miers 



Low succulent annual, simple or with many ascending branches, 

 2 — 7 cm. high; herbage of adult plant reddish; leaves ovate or oblong, 

 obtuse, 2 mm. long. 



There is a Tillaea common on sandy shores in Australia, f. i. at 

 Moreton Bay, Sydney, Port Phillip, Vincent's Gulf and Perth, and the 

 same form is said to occur in New Zealand and extratropical South 

 America. It is recognized as T. verticillata DC. by Bentham, but the 

 difference, if any at all, is inconpicuous between this form and T. 

 minima Miers., which is widely distributed in temperate South America 

 and California. When occurring on the coast this species is always 

 more succulent than in inland situations. 



T. moschata DC. 



Annual herb, with red creeping stems, 8 — 20 cm. long, succulent, 

 rooting from the axils; leaves 1 cm. long, entire, obovate, obtuse; 

 flowers comparatively large. 



Occurs in New Zealand and on adjoining islands, in Southern Chili 

 and Fuegia, as well as on several oceanic islands, as Falkland's and 

 Kerguelen's Land. 



T. muscosa L. 



Annual herb, 2 — i cm. high, much-branched, reddish, succulent; 

 leaves linear. 



In Western and Southern Europe from Mediterranean northwards 

 to Holland. 



HALORAGEAE. 



Gunnera arenaria Cheeseman. 



Fleshy glabrous herb, with slender rhizomes, tufted; leaves 3 — 5 

 em. long, ovate, petioles sheathing at base, with short flattened hairs on 

 upper part. This species shows a remarkable dimorphism in the form 

 of flowers, drupes and even nuts. 



Coastal sands of New Zealand.
