consumed by the autochthones [F. M. Bailey]/ Hicksbeachia 

 pinnatifolia (F. v. Mueller) is an allied small tree from Northern 

 New South Wales and Queensland. Culture might enhance the size 

 and quality of these fruits. 



Heliotropium Peruvianum, Linne. 



Andes of South- America. A perennial somewhat shrubby plant, 

 attaining a height of 6 feet. Among various species of Heliotrope 

 this one can best be utilised for the extraction of the scented oil. 

 Heliotropin obtainable from this and allied plants has been produced 

 synthetically also. 



Helipterum incanum, Be Candolle.* 



South-Eastern Australia, ascending to alpine elevations, and also 

 extending to the desert interior. Perennial. Worthy of special 

 culture even in cold regions. It displays a remarkaole variety of 

 colours. One variety is pleasantly odorous. 



Helipterum Mangles!!, F. v. Mueller. (Rhodanthe Manglesii, Lindley.) 



West- Australia. The most lovely of Australian annual everlast- 

 ings. Most easily raised from seed ; readily naturalised in adequate 

 soil and clime. Not disdained by sheep and cattle [Miss Alice 

 Eaton]. Headlets of flowers from a silvery to a rosy lustre. Of 

 leading beauty for nosegays, bouquets and wreaths ; its cultivation on 

 a large scale might develop an export trade in the same manner as 

 is the case with Helichrysum vestitum in South- Africa. Argyro- 

 come is the oldest generic name. 



Helleborus niger, Brunfels. 



Forest-mountains of Middle and Southern Europe, particularly in 

 sub-alpine regions. The Christmas-rose of British gardens. A 

 perennial handsome herb, remarkable for flowering even in cold 

 countries during mid-winter. The roots are used in medicine ; so 

 those of the still more powerful H. viridis (Linne) from the same 

 region. H. antiquorum (A. Braun), H. hiemalis (Linne), H. orient- 

 alis, and some other species are also winter-flowering plants. All 

 the species serve also as insecticides. Thrive best where lime prevails 

 in the soil. 



Helvella esculenta, Persoon. 



Europe. Dr. Goeppert notes among saleable Silesian mushrooms 

 for table-use this species as well as H. gigas (Krombholz) and H. 

 infula (Fries). Kohlrausch and Siegel found in H. esculenta when 

 dried 26 per cent, of protein, against the following other results : 

 in beef 39 per cent., in veal 44, wheat-bread 8, oatmeal 10, pulse 27, 

 potatoes 5, various mushrooms often 33 per cent. Of course starch, 

 sugar, inulin, pectin, gum and even fibre have to be further taken
