objects. They are kidney-shaped, and the surface is reticu- 

 lated with raised veins of a more or less hexagonal form. 

 Within the pits caused by this reticulation is a secondary, 

 fainter, and more minute reticulation. (PL II., fig. 

 20.) 



126. CORN SPURREY SEED (Spergula arvctuis). 

 Broadly ovate seeds, of a deep brown colour, with a pale, 

 sharp margin. The surface is sprinkled with club-shaped, 

 white, glandular hairs. The seeds arc rather large for 

 microscopical objects, but too characteristic to be omitted. 

 (PI. II., fig. 26.) 



127. CLIMBER SEED (Eccremocarpus scabcr}. This 

 common hardy climber is extensively cultivated. The 

 dark-coloured ovate seeds are surrounded by a transparent 

 wing, traversed by numerous branching veins. They are 

 sometimes viewed as opaque objects, and at others 

 mounted in balsam. By the latter means a beautiful 

 object is secured. (PL II., fig. 19.) 



128. LYCHNIS SEED (Lychnis diurna). Several species 

 of Lychnis furnish very similar seeds, of a reniform or 

 kidney shape, the surface regularly studded with warts or 

 short blunt spines. The garden Lychnis and wild Lychnis 

 dioica possess this character. (PL II., fig. 25.) 



129. SWEET WILLIAM SEED (Dianthus barbatus). The 

 seeds of this garden flower are heart-shaped, and gently 

 curved in the plane of their length. On the inside curve an 

 obtuse ridge runs in the direction of the length, rising into 

 a prominence near the middle of the seed. The colour 

 is nearly black, and minutely stippled with small depres- 

 sions. The figure gives an oblique view of the object. 

 (PI. II., fig. 39-) 



130. SATIN FLOWER SEEDS (SteUana holosteci). Oval, 

 almost kidney-shaped seeds, possessing much of the cha- 

 racter of lychnis seeds, the surface studded with warts. 

 Colour, pale brown. 



131. CHICKWEED SEED (Stellaria media). The seeds 

 of this common wayside weed are brown, ovate, with one 

 side produced to a bluntly pointed apex. Waved ridges 

 are disposed in several rows on the outer edge, gradually
