1 8 One Thousand Objects 



forming into star-shaped prominences in the centre. A well- 

 marked line divides the apex obliquely. (PI. II., fig. 29.) 



132. COREOPSIS SEED (Calliopsisbico/or). This favourite 

 composite annual has elongated, nearly spindle-shaped 

 seeds, blunt at each end, glossy black, and minutely and 

 regularly punctured. Each end is of a pale ochrey tint, 

 and obtuse. (PL II., fig. 22.) 



13*3. IVY BELLFLOWER SEED (IVahlenbergia hederaeea). 

 The seeds are of a light brown colour, smooth and 

 glossy, shaped like the back of a ' cowry ' shell, and 

 minute. They are chiefly of interest for the variety which 

 they furnish in a collection, than for any special attraction. 

 (PI. II., fig. 17.) 



134. ESCHSCHOLTZIA (Eschscholtzia tenuifoha). This 

 favourite flower has seeds of a form generally spherical, with 

 large triangular bluntly-pointed projections radiating from 

 the surface, giving the appearance of a rosette to the entire 

 seed. These prominences are obscurely dotted. The 

 general colour is light brown. (PL II., fig. 27.) 



135. PURSLANE (Portulaca olcracea). These seeds bear 

 some resemblance to the shells of the fossil Ammonites. 

 Rounded prominences with dark tips are arranged in spiral 

 rows upon the surface, each of which is surrounded by an 

 indented line on the surface of the seed. A peculiar 

 nacreous lustre gives this object a very beautiful appear- 

 ance. (PL II., fig. 38.) 



136. BLADDER CAMPION SEED (Silcnc inflate). The 

 general shape is reniform, with a slightly flattened projec- 

 tion at the concave part; the colour yellowish drab. On 

 the greater part of the surface rounded protuberances 

 Avith indented margins are deposited in alternate rows, fol- 

 lowing the convex outline. From the centre and over the 

 rest of the seed the indented line forms elongated irregular 

 cells. (PL II., fig. 31.) 



137. SANDWORT SEED (Lepigoxttm marinuni). These 

 seeds have something the character of those of Eccremo- 

 carpus, being ovate and surrounded by a transparent wing, 

 the venation of which differs from that of the seed named.
