224 DISPERSAL 



Caryophyllaceae, Delphinium, Iridaceae, Liliaceae, Papaver; winged 

 seeds in Bignoniaceae Bromeliaceae, Casuarina, Millingtonia, Pinus, 

 Zanonia; winged fruits in Abronia, Aceraceae, Bignoniaceae, Car- 

 pinus, Dipterocarpaceae, Fraxinus, Liriodendron, Malpighiaceae, 

 Ptelea, Pterocarpus. Rumex, Serjania, Terminalia, Tripteris. Ulmus, 

 Ventilago ; hairs, forming a parachute mechanism, in seeds of Apo- 

 cynaceae, Asclepiadaceae, Epilobium, Gossypium, Salix, &c., in 

 fruits of Anemone, Clematis, Compositae, Eriophorum, Typha, 

 Valerianaceae, &c. 



By animals are carried, as inside passengers, the seeds in edible 

 fruits (</&.), and as outside passengers the hooked fr. of Asperula, 

 Bidens, Blumenbachia, Cenchrus, Circaea, Daucus, Galium, Geum, 

 Harpagophytum, Martynia, Medicago, Tragoceros, Triumfetta, 

 Xanthium, &c., the glandular fr. or seed of Allionia, Boerhaavia, 

 Pisonia, Plumbago, Siegesbeckia, &c. By water Cerbera, Cocos, 

 Crinum, Nuphar, Nymphaea, Potamogeton, &c. By explosive 

 mechanisms are scattered the seeds of Alstroemeria, Balsaminaceae, 

 Biophytum, Buxus, Cardamine, Cyclanthera, Dorstenia, Ecballium, 

 Elaterium, Eschscholtzia, Geranium, Hura, Impatiens, Ricinus, 

 Ulex, Viola, &c. As a general rule, the dispersal of seed by any 

 of these mechanisms is only to a very small distance, but they may 

 at any time be of great importance by enabling transport over long 

 distances.
