plant are remarkable for the barbed tuft of hair which 

 they bear. At the opposite end a well-marked notch is 

 seen.. As they are very large, only an inconsiderable mag- 

 nifying power is required. (PI. II., fig. 40.) 



152. EUCHARIDIUM SEED (Eucharidium concinnuni). 

 Singular elongated and brown seeds, convex on one side, 

 and on the other concave or spoon-like at one end, with 

 a cleft extending nearly to the other. The entire surface 

 reticulated and sculptured. (PI. II., fig. 41.) 



153. INDIAN PIMPERNEL SEED (Anagallis Indica).- 

 Broadly ovate or irregular, presenting a triangular face. 

 At first covered with membranaceous warts, which in 

 drying shrivel into conical projections. (PI. II., fig. 42.) 



154. ISOTOMA SEED (Isotoma longiflora}. Neat little 

 seeds of an oblong shape and amber colour. Regularly 

 reticulated so as to leave shallow hexagonal pits over the 

 whole surface, which is clear and shining. 



155. FOXGLOVE SEED (Digitalis pnrpurea}. Cylindrical 

 with blunt ends, and a shallow longitudinal groove. Sur- 

 face minutely honeycombed. Digitalis littea has similar 

 seeds, but not so attractive or regular. (PI. II., fig. 43.) 



156. LOUSEWORT SEED (Pcdicularis palustris). Pear- 

 shaped, with a curved cleft or groove on one side. The 

 surface finely reticulated. Of a shining, chocolate-brown 

 colour. (PI. II., fig. 44.) 



157. VERBENA SEED (Verbena pulchdld). Long, nar- 

 row seeds, traversed on one side with a broad shallow 

 groove, terminating in a point at one end and a spatula 

 at the other; the groove with a central ridge covered with 

 granular papillae. (PI. II., fig. 45.) 



158. EUTOCA SEED (Eutoca multiflord). These seeds 

 are long, elliptical, with pointed ends, of a dull brown 

 colour, and the surface deeply punctured with pentagonal 

 pits. A similar structure is found in Whitlavia grandi- 

 flora. 



159. SMALL SNAPDRAGON SEED (Artirrhinwn oron- 

 tiuni). With an oblong outline, flattened on one side, 

 and on the other deeply hollowed, with five or six large 

 papillae around the depression. The whole surface mi-
