LUriNUS 



LUPINUS 



united into a closed tube : pod 2-valved, flattened, en- 

 closing several large seeds. A very variable genus in 

 the garden. 



There are numerous garden hybrids of unknown par- 

 entage. Some of these names will be found in the sup- 

 plementary list. Voss groups these under the name of 

 L. hybridus, Hort., or Florists' Lupines. They have 

 variegated flowers. 



In addition to those described below the following na- 

 tive species have been advertised, mostly by Gillett, in 

 1881, for western collections. Probably they are not 

 in cult. They are mostly described in Bot. Calif. : L. 

 albicaulis, Chamissonis, densiflorus, lepidus, leuco- 

 phyllus, ornatus and villosus.
