| 2. G. submersum Petrie in Trans. N.Z. Inst. xxiii (1891) 401.— 
A minute very slender intricately branched plant, forming small but dense 
matted patches; stems creeping and rooting at the nodes. Leaves 
opposite or fascicled, #g—}in. long, linear or narrow linear-spathulate, 
quite entire, gradually narrowed into a petiole equalling the blade or 
rather shorter than it. Peduncles slender, axillary, about as long as the 
leaves. Flowers very minute, zgin. diam. Calyx obtusely 3-lobed. 
Corolla small, not much longer than the calyx; lobes short, rounded. 
Stamens 2, included. Capsule not exceeding the calyx, globose, in. 
diam, 
SoutH Istanp: Otago—Tidal shores of Lake Waihola, usually submerged at 
high water, Petrie / 
A very curious little plant, apparently closely allied to the Queensland G. spathu- 
latum Arn., but my flowering specimens are insufficient for a proper comparison. 
I have seen no specimens except those gathered by Mr. Petrie. 
6. LIMOSELLA Linn. 
Small tufted creeping glabrous marsh o1 aquatic plants. Leaves oppo- 
site or fascicled at the nodes, rarely alternate on barren shoots, long- 
petioled, linear or spathulate, quite entire. Flowers minute, axillary, 
solitary, Calyx campanulate, 5-toothed or -lobed. Corolla campanulate 
or almost rotate; tube short; lobes 5, nearly equal. Stamens 4; fila- 
ments filiform; anther-cells confluent. Ovary 2-celled at the base ; 
style short; stigma clavate or subcapitate. Capsule obscurely dehiscent 
or septicidally 2-valved; valves thin, membranous. Seeds numerous, 
small, ovoid, transversely rugulose. 
A genus comprising 6 or 7 species, found in most parts of the world. 
Leaves 3-13 in. long; lamina not much broader than the petiole. 
Flowers pedicelled ; corolla and capsule longer than the calyx.. 1. ZL. tenuifolia. 
Leaves 2-5in. long; lamina ovate, suddenly contracted into the 
slender petiole. Flowers sessile; corolla and capsule shorter 
than the calyx .. 4 , . 2. L. Curdieana.

1. L. tenuifolta,Nutt. Gen. N. Amer, ii (1818) 43—Annual or perennial, 
creeping and tufted, often forming patches 1-2 in. diam. or more. Leaves 
densely fascicled, $-I4in. long, rarely more, narrow-linear or linear- 
subulate, often with little or no distinction between petiole and blade, 
but sometimes dilated towards the tip and becoming narrow linear-spathu- 
late. Flowers minute, 7g in. diam., axillary, on very short pedicels. Calyx 
5-toothed, Corolla rather longer than the calyx; lobes ovate-oblong. 
Capsule ovoid-globose, exceeding the calyx when mature.—Cheesem. Man.

to 3000 ft. . November—February. 
Often considered to be a variety of the widely diffused L. aquatica Linn., but the 
leaves have not the conspicuous lamina of that species, and the whole plant is usually 
much smaller. It also occurs in Australia and Tasmania, in temperate North and 
South America, and in some parts of Europe.
