African and Madagascar Flowering Plants. 381 
have a white dot at the tube-entrance ; there are three distinct 
longitudinal rowsof hairs along the claw. This is a dimorphic 
species (cf. Muller, p. 545). One form is exactly like another 
species, No. 1095 ! while in the other the arrangement is much 
like that of Moraea tristis, No. 1148! Visitors: — Anisonyx 
ursns and other Coleoptera. 
Moraea trieuspis, Ker (No. 1096! Figs. 135-137). 
The style-branches are supported on a very distinct 
column in this species. The internal perianth-segments end 
in a peculiar three-lobed tip (see Fig. 135), while the external 
perianth-segments are distinctly concave and possess at the 
base a small square scale which forms a pouch for the honey. 
Visitors : — Coleoptera : Anisonyx ursus , which I saw crawling 
down the external perianth-segment and sucking the honey. — 
Sea Point, Cape Town. 
Moraea angusta, Ker (Nos. 1095! 1150! 1198! Figs. 138- 
140). 
The flower is large and in this species each style-branch 
and its corresponding external perianth-segment are closely 
approximated to form a complete tube as in Iris. The inner 
perianth-segments prevent the entrance of small insects at the 
base. In some cases however this tube was not complete (cf. 
Muller, 1 . c. p. 545.) Visitors: — -Hymenoptera : Ceratina sp., 
ants stealing honey. Diptera : Pangonia angulata , Lucilia 
argyrocephala , and others. Coleoptera : Anisonyx ursus , 
Dichilus simplicipes , and another sp. (No. 186.) — Devils Mtn. 
and Washhouses. — Cape Town. 
Moraea papilionaeea, Ker (Fig. 141). 
Except for the presence of large internal perianth-seg- 
ments, this scarcely differs from the preceding. Visitors : — 
Apis mellifica , very ab. covering its back with pollen, 
visiting each segment of the flower and crawling backwards 
out of each (cf. Sprengel, 1 . c. No. 702 and Muller, l.c. p. 54 5 )> 
also ants stealing honey and Empis bivittata , sucking.
