crown of the roots, and forms a dense caespitose tuft which 

 could not be dried without subdivision. The plate (Journ. Bot. 

 1897, t. 371) admirably represents the younger state, the erect 

 leaves^ giving it quite a distinct look, but in older plants the 

 crowding of the leaves still erect gives them a different appear- 

 ance, longer and narrower and more toothed," The plant 

 figured by Beguinot in his Bevisione as P. Coronopus var. cerato-

 Flora of Portugal. 



WAYFARING NOTES IN RHODESIA.'* 



By R. F. Rand, M.D., F.L.S. 



(Concluded from vol. xlix. p. 249.) 



AcALYPHA. A. villicaulis Rich. (no. 1384), A. Allenii Hutch. t 

 (nos. 1385, 1386), A. ciliata Forsk. (no. 1388), and Tragia sp., 

 near T. Schinzii Pax I (no. 1387). All are nettle-like, and all are 

 monoecious. The first two have anemophilous flowers. No. 1387 

 is entomophilous. No. 1388 requires further study, and may 

 prove to be entomophilous. Its ** drip- tip " is noticeable, few 

 Rhodesian leaves having that feature ; it is usually seen in her- 

 baceous annuals whose short life begins and ends with the rains. 



A. VILLICAULIS Rich. The styles and stigmas are red. The 

 apical position of the female flowers, while giving free access to 

 wind-borne pollen, preserves them from the pollen gravitating 

 from the male spikes lower down upon the stem. There is also 

 the advantage that in time of fruit the exploding cocci have a 

 wider range and an uninterrupted flight. 



A. Allenii Hutch. The styles and stigmas are green. 

 No. 1386, the same species as No. 1385, shows a curious character. 

 The apical female spike, after its fruit is well set, develops a 

 prolongation of its axis which bears male flowers ; this, after the 

 male spikes lower down upon the stem have withered. Lateral 

 branches lower down upon the stem may be found bearing female 

 spikes, and the late male development may be with a view to 

 their pollination. The reversal in the position of the flowers in 

 the ageing plant is interesting. 



Teagia sp. near T, Schinzii Pax. A loose, straggling herb, 

 with stinging hairs. The racemes are carried upright, all the 

 flowers being male with the exception of the lowest one, which is 

 female. 



Male floioers. — Perianth-lobes 3. Stamens 3. Filaments short, 

 bowed outwards, carrying a hooded anther above, the opening into
