another species In this genus. Cremolobus rTiomhoideitSy Hook. 

 le. PL 32, and C. simiahiSy Hook. Ic. PL 99, are both founded on 

 specimens sent "by Jameson from the Cuesta de Purruchuco in 

 Peru, and an examination of the original type shows clearly that 

 they are forms of the same species. C. simiattis is founded on a 

 depauperate specimen in which the silicules are quite wingless.

MoNisiNA GBTusiroLiA, S, B. -ST., var. ? Chicla ! This plant 

 helougs to a group which demands the careful study of all the 

 available materials. My plant appears to be exactly the same as 

 two unnamed specimens in Herb. Kew collected by Mathews in 

 Peru near Chachapoyas, and numbered 1517 and 1518. To the 

 same species must also, I think, be referred his number 3024, 

 also from Chachapoyas. The latter is attached to the same sheet 

 with a specimen labelled Monnina ptibescens^ H. B. K. ?, but 

 cannot be referred to that species. My plant is evidently nearly 

 related to M. oltusifoUa, H. B. K., and Jf. crassifolia^ H. B. K. ; 

 and I provisionally rank it as a variety of the former.

Lychnis cuilensis, Naiid. in 0. Gay^ Fl. CJnL i. p. 256, var. 

 rERUTiANA, nob. Chicla ! This belongs to a group of forms, all 

 nearly allied to the Arctic X. apetala, L., which extend in 

 S.America from the equator to tlie Straits of Magellan. From 

 a cursory examination of numerous specimens, I am led to con- 

 clude that they may best be reduced to three species, as follows : 



1. Z. thi/sanodes^ Hook, fil, FL Antarct. ii. p. 2163=Silene thy- 

 sanodes, Fenzl.y in Eudl. Nov. Stirp. Dec. Xo. 39, = Silene andicola, 

 GilL^ in Hook. Bot. Misc. iii. p. 147. Melandrynm cucnbalodes, 

 FenzL, quoted by Grisebach (PL Loreuz. p. 2S), probably belongs 

 also to tliis species ; but I am unable to identify it with certainty, 



Tliis has relatively broad leaves ; the stems usually have many 

 flowers, which are drooping before fertilization. The calyx is 

 rather less deeply cleft than in the following species, and the 

 outer nerves of each of the adnate segments formine^ the calvx-
