Naturalisation in Extra-Tropical Countries. 261 



Hyphaene Argun, Martius. 



Nubia, to 21 north-latitude. Possibly hardy anywhere on low- 

 lands in the warmer temperate zone. 



Hyphaene coriacea, Gaertner. 



Equatorial Eastern Africa ; the dichotomous Palm of the sea-coast- 

 regions. It attains a height of 80 feet. Deserving of cultural trials 

 in cooler latitudes also. 



Hyphsene crinita, Gaertner. (H. Thebaica, Martius.) 



The Gingerbread-Palm or Doum-Palm. Abyssinia, Nubia, Arabia 

 and Egypt, as far as 31 north latitude, and southward to the Zambesi, 

 Nyassa and Sofala. In Arabia to 28 north latitude [Schweinfurth]; 

 up to the plateau of Abyssinia [Drude]. It is much branched, and 

 attains a height of about 30 feet. The mealy husk of the fruit is 

 edible. 



Hyphaene ventricosa, Kirk. 



Zambesi. Loftier than the other species. Stem turgid towards the 

 middle. Fruit large. Perhaps not absolutely requiring a tropical 

 clime. 



Hypochceris apargioides, Hooker and Arnott. 



Chili. A perennial herb. The root is used for culinary purposes 

 like that of Scorzonera Hispanica. 



Hypochceris Scorzonerae, F. v. Mueller. (Achyrophorus Scorzonerce, D.C.) 

 Chili. Of the same use as H. apargioides. Allied species of 

 probably similar utility exist in Western South- America* 



Hypoestes moschata, F. v. Mueller and Holtze. 



Arnhem's Land. This perennial herb is pervaded by a singularly 

 penetrating musk-scent, so that from the foliage a powerful perfume 

 can be distilled, the odorous principle not being subject to chemical 

 decomposition through gentle heat [W. Carr-Boyd]. As a dried herb 

 it could well be utilised for scenting wearing apparel, paper and other 

 articles ; Mimulus moschatus, Aster argophyllus, A. myrsinoides, 

 A. moschatus, A. ilicifolius (the two latter from New Zealand), and 

 Moschosma polystachya might be similarly employed. 



Hyssopus officinalis, Linne. 



South-Europe, South- Western Asia. A perennial herb, discarded 

 and re-introduced in medicine. The essential oil of this herb is also 

 used for some perfumeries.
