11. + Dusty (f lentiginosus) ; covered with minute dots or specks, as if dusted ; 



the calyx and corolla of Ardisia lentiginosa. 



12. Frosted (pruinosus); nearly the same as roridus, but applied to surfaces in 

 which the dewy appearance is more opaque, as if the drops were congealed ; 

 as the surface of the leaves of Rosa pruinosa and glutinosa. 



13. Powdery (pulverulentus) ; covered with a fine bloom or powdery matter ; as 

 the leaves of Primula farinosa. 



14. Glaucous (glaucus) ; covered with a fine bloom of the colour of a Cabbage. 



15. Csesious (ccesius) ; like glaucous, but greener. 



16. Whitened (dealbatus); covered with a very opaque white powder; as the 

 leaves of many Cotyledons. 



4. Of Texture or Substance. 



1. Membranaceous (membranaceus) ; thin and semi transparent, like a fine mem- 

 brane ; as the leaves of Mosses. 



2. Papery (papyraceus, chartaceus) ; having the consistence of writing-paper, 

 and quite opaque ; as most leaves. 



3. Leathery (coriaceus, + alutaceus*) ; having the consistence of leather ; as the 

 leaves of Pothos acaulis, Prunus Laurocerasus, and others. 



4. Crustaceous (crustaceus); hard, thin, and brittle ; as the testa of Asparagus, 

 or of Passiflora. 



5. Cartilaginous (cartilagineus) ; hard and tough ; as the seed of an apple. 



6. Loose (laxus); of a soft cellular texture, as the pith of most plants. The 

 name is derived from the parts of the substance appearing as if not in a 

 state of cohesion. 



7. Scarious (scariosus) ; having a thin, dry, shrivelled appearance ; as theinvo- 

 lucral leaves of many species of Centaurea. 



8. Corky (suberosus) ; having the texture of the substance called cork ; as the 

 bark of Ulmus suberosa. 



9. Coated (corticatus) ; harder externally than internally. 



1 0. Spongy (spongiosus) ; having the texture of a sponge ; that is to say, very 

 cellular, with the cellules filled with air ; as the coats of many seeds. 



1 1 . Horny (corneus) ; hard, and very close in texture, but capable of being cut 

 without difficulty, the parts cut off not being brittle ; as the albumen of 

 many plants. 



12. Oleaginous (oleaginosus); fleshy in substance, but filled with oil. 



13. Bony (psseus); hard, and very close in texture, not cut without difficulty, the 

 parts cut off being brittle ; as the stone of a peach.

15. Waxy (ceraceus, cereus) ; having the texture and colour of new wax ; as the 

 pollen masses of some Orchids. 



1 6. Woody (lignosus, liyneus) having the texture of wood. 



17. Thick (crassus); something more thick than usual. Leaves, for instance, 

 are generally papery in texture ; the leaves of cotyledons, which are much 

 more fleshy, are called thick. 



18. Succulent (succulentus); very cellular and juicy ; as the stems of Stapelias. 



19. Gelatinous (gelatinosus) ; having the texture and appearance of jelly; as 



Ulvas, and similar things. 



20. Fibrous (fibrosus) ; containing a great proportion of loose woody fibre ; as
