culinary species occurs on the Senegal. H. digitalus (Cavanilles) 

 is another cognate species of similar utility from Brazil. H. 

 punctatus (Dalzell and Gibson) is mentioned as an annual fibre- 

 plant, occurring in Sindh and Mooltan. 



Hippopbae rhamnoides, Linne. 



Europe, Western and Central Asia. One of the best of shrubs 

 for binding sand on sea-shores. Ascends to 15,000 feet in Thibet. 



Hierochloa redolens, E. Brown. 



South-Eastern Australia, there almost confined to the Alps ; also 

 in New Zealand, in the Antarctic Islands and the southern extremity 

 of America. A tall, perennial, blady grass, with the odor of 

 Anthoxaiithum. It is worthy of dissemination on moist pasture- 

 land in cool countries. H. borealis of the colder regions of the 

 northern hemisphere accompanies H. redolens in the south, but is 

 a smaller grass. These grasses are to some extent valuable for 

 their fragrance as constituents of hay, the odorous principle, as 

 in Anthoxanthum, Melilotus and Asperula, being cumarin. 

 Hierochloas are particularly appropriate for cold, wet, moory 

 grounds. 



Hippocrepis comosa, Linne. 



The Horse-shoe Vetch. Middle and Southern Europe, North- 

 Africa. A perennial fodder-herb, not without importance. Likes 

 stony ground, and delights like most leguminous herbs in limestone - 

 soil. The foliage is succulent and nutritious. Professor Langethal 

 recommends it for a change after Sainfoin-pastures fail. It fur- 

 nishes not quite as much but an earlier fodder. 



Holboellia acuminata, Lindley. 



In the Himalayan mountains at 4-9,000 feet elevation. Under 

 the above name H. latifolia and H. aiigustifolia are united, as 

 neither of the two appellations, given by Wallich, applies to the 

 species as a whole. The berries (fruitlets) of this climbing shrub 

 are large, and in the natural localities of the plant consumed for 

 food. They may on culture get ameliorated ; they remind in taste 

 of the fruit of the Passion-flower. 



Kolcus lanatus, Linne. 



Velvet-grass or Meadovv-Softgrass, also known as Yorkshire- 

 foggrass. Europe, North-Africa, Middle Asia. Indigenous in 

 Norway to lat. 63 34 '. A well-known and easily disseminated 

 perennial pasture-grass of considerable fattening property. For 

 rich soil better grasses can be chosen, but for moist, moory or sandy 

 lands and also for forests it is one of the most eligible pasture- 

 grasses, yielding an abundant and early crop ; it is however rather 

 disliked by cattle as well as horses. One of the best rural grasses
