rounded leaves still form as dense masses of greenery as in 

 summer."* 



Campbell Island : " It accompanies Ligusticum latifolium 

 down to the stony beach, but not quite so near the water's 

 edge " (p. 270). " In the DracophyUum scrub it follows the 

 many watercourses which cut into the hillside, and grows luxuri- 

 antly in the running water" (p. 273). ''It is found in the deep 

 gullies cut into the sides of the scrub formation " (p. 274). 



Antipodes Islands : Inland tussock sloj^es. Frequently fern, 

 tussock, and scrub give place to great masses of Stilbocarpa 

 polaris, forming dense thickets. " One colony of this remark- 

 able plant measured 11 m. by 3 m., but those met with further 

 on, of which no measurements were taken, were of much larger 

 size " (p. 292). 



Anatomy (figs. 9a, 96). — The upper epidermal cells (ep.) 

 are large, rectangular, and slightly cuticularised, while those of 

 the -lower epidermis are much smaller and have no cuticle. Sto- 

 mata (st.) are found under the surface only. The hairs (h.h.) 

 are solid multicellular bodies arising below the veins on the 

 under surface, and in the areas between the veins on upper. 

 Below the epidermis is usually a layer of colourless cells with 

 thinner walls, probably water-storage tissue (st.l.). The chloren- 

 chyma is differentiated into palisade (pal.) and spongy (sp.). 

 The palisade (pal.) consists of four layers of small oval-shaped 

 cells, closely packed together, and very regularly filled with 

 chlorophyll. Below this conies the first portion of the spongy 

 tissue, which consists of larger, more rectangular, and colourless 

 parenchyma cells, arranged in chains. Then occurs a large 

 air-chamber separating this last layer from the layer of very 

 small rounded cells densely filled with chlorophyll. The two 

 layers are united at certain parts of the leaf where the veins 

 occur. The vascular bundle (v.b.) is surrounded by a thick- 

 walled endodermis, and is strengthened on the under surface 

 by a little mass of hypodermal stereom tissue, and also by a 

 further mass of collenchyma. This tissue in some cases con- 

 tains a certain amount of chlorophyll where it joins the endo- 

 dermis. The epidermal cells (ep.) immediately below the veins 

 are larger than ordinary, and oval, with projecting outer walls.
