300 APPENDIX. 



nodding flowers, according to his description (Sched. 259). The 

 T. collinum of Koch (Deutschl. Flora, iv. 130) may be the same as 

 that of Wallroth; but Fries informs us that the latter author 

 denied their identity, and he therefore names the plant T. Kochii. 

 I have thought it safest to follow Fries in a case of so much 

 difficulty, and now use the name of T. Kochii for the T. saxa- 

 tile of my Manual, ed. 4.

We have unquestionably two plants confounded under this 

 name in England, both of which occur in Cambridgeshire. It is 

 probable that they have escaped notice owing to the early hour 

 in the day at which the petals fall. When perfectly full-blown 

 flowers are contrasted their differences are conspicuous. Many 

 differences are also to be found in their ripe capsules, the colour 

 of their sap, &c. 



Our plants may be characterized and described as follows : 

 1. P. Leciqii (Lamot.) ; filaments subulate ; stigmatic disk 

 broader than the capsule and folding over its edge, convex- 

 conic, ultimately flat ; capsule oblong, club-shaped, suddenly 

 narrowed near the base, which is narrower than the torus ; 

 leaves bipinnatifid, with distant, narrow, entire, acute lobes.

 p. 279, tab. 14, f. 11. 

 Sap of the whole plant turning dark yellow (ochraceous) in 

 the air. Filaments violet ; anthers brownish, just level with the 

 stigmatic disk. Stigmatic disk of the ripe capsule quite flat. 

 Stigmatic rays very nearly, but not quite, reaching to the edge 

 of the disk, which is obscurely but angularly lobed : the lobes are 

 bluntly triangular at their end, or even tricrenate (that is, 

 having three crenatures), and deeply divided from each other 

 but rather overlapping below. This disk is broader than the 

 top of the capsule. Seeds reniform, netted. Hairs on the pe- 

 duncles all adpressed: those on the leaves bubous-based. 



It is probable that this is the P. Lecoqii (Lamot.\ although 

 that plant is stated to have suborbicular petals and stigmatic rays
