Peltophorum Iiinnaei, Bentham (Ccesalpinia Brasiliensis, Linne.) 



A small tree, which provides the orange-colored Brasiletto-wood. 

 This species likes dry calcareous soil [Grisebach]. Endures the 

 climate of Carolina. 



Pennisetum cenchroides, Cl. Bichard. 



Africa and South- Western Asia. Perennial. The Unjum or 

 Dhaman or Anjam. At Allahabad this is regarded as a first-rate 

 fodder-grass. [Dr. Stewart]. Well adapted for silos [General Sir 

 H. Macpherson]. In its own countries one of the best of grasses 

 for green fodder and hay ; so nutritious as to have led to the 

 native saying: "What Ghi (or Ghee, i.e., clarified butter) is to 

 man, that* the Dhaman is to a horse " [Prof. Robert Wallace]. 



Pennisetum Arnhemicum, F. v. Mueller. 



North- Australia and Queensland. This grass remains strong 

 and green through the hottest months, forming compact tussocks. 

 All kinds of pasture-animals are very fond of it [Molineux]. 



Pennisetum latifolium, Sprengel. 



Extra-tropical South- America. A tall perennial nutritious grass, 

 forming large tufts, easily spreading from the roots or seeds. It 

 is of quick growth. 



Pennisetum ty phoideum, Kichard.* (Penicillaria spicata, WilWenow ; 

 Panicum ccerulevbm, Miller.) 



The Bajree or Pearl-Millet. Tropical Asia, Nubia and Egypt. 

 An annual, requiring only about three months to ripen its millet- 

 crop in warm countries. The stems are thick and reach a height 

 of 610 feet, several being produced from one root, and each again 

 forming lateral branches ; the maximum-length of a spike is about 

 a foot and a half ; Colonel Sykes saw exceptionally 15 spikes on 

 one plant and occasionally 2,000 seeds in one spike. Together with 

 sorghum this is the principal cereal, except rice, grown in India by 

 the native races. This grass requires a rich and loose soil, and on 

 such it will yield upwards of a hundred-fold. It furnishes hay of 

 good quality, though not very easily dried, and is also valuable as 

 green fodder. In the United States cultivated as far north as 

 Pennsylvania, and it matures seeds even as far north as Christiania 

 in Norway [Schuebeler]. Thrives fairly well at Port Phillip. 

 Its fast growth prevents weeds from obtaining a footing. In very 

 exceptional cases and under most favorable circumstances as regards 

 soil and manure, the first cutting is in six or seven weeks, the 

 stems up to seven feet high, giving at the rate of 30 tons green feed, 

 or 6-| tons of hay per acre ; in six or seven weeks more a second 

 cutting is obtained, reaching 55 tons per acre of green feed, the 

 grass being nine feet high ; a third cut is got in the same season. 

 Farm-stock eat it greedily. One plant of pearl-millet " is worth
