Hydro-xerophytes (bog xerophytes) .Plants which live in ~t, peaty soils, and which possess aeration channels and xeroiilous leaves; e.g., Cladium Mariscus, Eriophorum angustifohium, if bus Chamaemorus, and Vaccinium Vitis-Idaea.
Some such species are Blechnum boreale, Aira flexuosa, Calluna vulgaris, Vaccinium, Myrlillus, Rubus, Chamaemorus, Empetrum nigrum, Drosera spp. Some, at least, of these species possess mycorhiza in their roots, and are perhaps unable to live in soils where such organisms are absent.
The red whortleberry or cowberry (Vaccinium Vitis idaea), the bog whortleberry (V.
About the only indigenous fruit-bearing plants are the Chilean strawberry (Fragaria chilensis) and the ohelo berry (Vaccinium reticulatum), both of which grow at high elevations on Hawaii and Maui.
A low blueberry (Vaccinium myrtilis) forms a thick underbrush in much of the forest.
In many cases the slimy masses of spermatia (Uredineae), conidia (Claviceps), basidiospores (Phallus, Coprinus), &c., emit more or less powerful odours, which attract flies or other insects, and it has been shown that bees carry the flagrant oidia of Sclerotinia to the stigma of Vaccinium and infect it, and that flies carry away the foetid spores of Phallus, just as pollen is dispersed by such insects.
Heteroica, is heteroecious; the ascospores infecting the leaves of Vaccinium uliginosum, while the conidia which then arise infect only Ledum palustre.
Professor Fernald concludes his paper by saying that: "The mass of evidence which the writer has in hand, and which will soon be ready for publication, makes it clear that, if we read the sagas in the light of what we know of the abundant occurrence north of the St Lawrence of the vinber' (Vaccinium Vitis-Idaea or possibly Ribes triste, R.
