Daucus (Orlaya) grandiflora, Hoffm.—tThis species has three — 
different kinds of flowers, all differmg in form and degree of 
conspicuousness: (1) In the centre of the umbellule the florets _ 
are male only, and have small incurved petals; (2) at the edge of — 
the umbellule the florets are asexual, and the outermost petal is ~ 
greatly enlarged; (3) at the margin of the whole umbel are ~ 
female florets, in which the outer petals attain a gigantic size ~

REVIEW OF THE UMBELLIFERA, 
A survey of the Umbelliferee and their insect-guests proves — 
most definitely that in flowers. otherwise constituted alike the 
visitors vary in abundance and variety in proportion to the con- 
spicuousness of the flowers. For our comparison we must naturally — 
choose flowers that have been observed to much the same extent. — 
If we select a number, eg. Agopodium, Carum, Pimpinella 
Saxifraga, Heracleum, Torilis, Anthriscus silvestris, Daucus, and 
Cherophyllum temulum, and arrange them in the order of con 
spicuousness, this arrangement will not differ materially from tk 
following, in which they are placed according to the number o 
? The following additional species are discussed in my Alpenblumen ;—Bupleurum 
stellatum, ls. ; Cherophyllum Villarsii, Koch. ; Gaya simplex, Gaud. ; Loserpiti 
hirsutum, Lam. ; Mewm Mutellina, Girtn. ; Peucedanum Ostruthiwm, L. Lists o 
visitors to the following are given in my Weitere Beobachtungen, pt. 1. ; thusu
