 ('Alpenblumen/ p. 116). Schletterer and von Dalla Torre (Tyrol) the bee Prosopis 

 borealis Nyl. Kohl the fossorial wasp Crabro scutellatus Schev. MacLeod (Pyrenees) 

 a bee and 2 flies (Bot. Jaarb. Dodonaea, Ghent, iii, 1891, pp. 413-14). Scott-Elliot 

 (Dumfriesshire) a saw-fly, 2 Ichneumonids, 5 Muscids, and several Dolichopodids 

 ('Flora of Dumfriesshire,' p. 76). 



335. Pimpinella L. 



1117. P. magna L. (Schulz, 'Beitrage/ I, p. 43, II, pp. 82-4, 91, 190.) 

 Schulz, for Germany and the Tyrol, describes this species as andromonoecious, with 

 protandrous hermaphrodite flowers. Gelmi and Schulz, in the South Tyrol, observed 

 a purely female form with partly or completely degenerate pollen : the central flowers

of the umbels were neuter, instead of being male as usual. Gelmi states that the 

 styles are always shorter than the ovary in the hermaphrodite flowers, but longer in the 

 purely female ones. The same is true for P. saxifraga. At Ruppin, according to 

 Warnstorf, the umbellules of primary umbels bear hermaphrodite flowers ; those of 

 secondary umbels marginal hermaphrodite and central male ones; tertiary umbels 

 male flowers only. 



Visitors. The following were recorded by the observers, and for the localities 

 stated. 



Herm. Muller (Central Germany), 2 bees (Andrena parvula K. $>, skg. and 

 po-cltg. ; A. rosae Pz. $, skg.) ('Fertilisation/ p. 277); in the Alps a Cerambycid 

 beetle (Pachyta quadrimaculata L.) ('Alpenblumen/ p. 116). Sickmann (Osnabriick), 

 2 fossorial wasps (Crabro dives Lep., rare; Mellinus sabulosus F.). MacLeod 

 (Pyrenees), a beetle (Bot Jaarb. Dodonaea, Ghent, iii, 1 891, p. 413). 



In the sub-Alpine region this species usually bears rose-red flowers (var. $ rosea 

 Koch, = the species Pimpinella rubra Hoppe), and the styles and stigmas appear to be 

 developed to such an extent in the first (male) stage, that they might be regarded as 

 mature, but as a matter of fact they do not attain their full size till later.
