Ewart, A. J., The systematic position of Hectorella caespitosa, 
Hook. f. (Journ. Linn. Soc. XXXVIII. 263. p. 1—3. 1 fig. 1907.) 
Hectorella, Hook. f. is a New Zealand monotype, which the 
author placed in the Portulacaceae , with the remark that it was 
allied to no other genus, but similar in habit to the Kerguelen 
Lyallia, Hook. f., which is another monot3^pe referred to the Alsi- 
noideae-Polycarpeae group of the Caryophyllaceae. Dr. Ewart argues 
that there is nothing in the structure of Hectorella to connect it 
with the Portulacaceae rather than with the Alsineae-Polycarpeae. 
The pair of leaves just below the perianth in Lyallia have been 
described as proph}dls and in Hectorella as sepals. Dr. Ewart regards 
them as of the same nature in both, and the petals of other authors 
of Hectorella as sepals. He suggests, too, that the “sepals” in the 
Portulacaceae as a whole may be capable of the same interpretation.

A brief comparison between the Vegetation of Novaja Zemlja, 
the North West coast of Greenland and James’ peak in Colorado 
at an elevation of about 12,000 feet. Eleven circumpolar species were 
found by the writer on James’ peak viz: Trisetum subspicatum, 
Festuca ovina, Luzula spicata, Oxyria digyna, Polygonum viviparum, 
Artemisia borealis, Dryas octopetala, Saxifraga flagellaris, S. cernua, 
S. nivalis, and Silene acaulis; besides these Carex rupestris, Aira 
caespitosa, and Lloydia serotina were eollected, but these are not 
circumpolar, although they are widely distributed in the arctic region. 
Among the most characteristic species of the American element, 
that was observed on this same peak may be mentioned: Trifolium 
Parryi, T. dasyphyllum, Sieversia turbinata, Heuchera bracteata, 
Stenotus pygmaeus, Erigeron simplex, Actinella grandiflora, Castille ja 
brevißora, C. septentrionalis, Carex chalciolepis cet. cet.
