shortly bifid, white-tomentose above, glabrescent beneath ; the 
a piaehes of the spadix are also stouter. South Argentina, 
TRITONIA. According to J. G. Baker, this genus 
now embraces upwards of thirty species. 
The Montbretia section is the most popular with 
gardeners, on account of the very gracefully disposed 
flowers and elegant foliage. The colour-range is not a 
large one—usually some shade of orange or yellow—and 
they are most useful for furnishing cnt-flower material. 
The older but still beautiful M. Pofttsii, and one or two 
others once favoured, have been to a certain extent 
superseded by the garden varieties (Fig. 730), a list of 
which will be found below. The bulbs of this section 
are best planted in autumn, lifted annually on heavy 
soils, and replanted in fresh quarters; but upon light 
ones they need not be disturbed oftener than every two 
or three years. 
To the species described on pp. 94-5, Vol. IV., the 
following should be added. Some of the plants formerly 
known as Tritonias are now classed under Acidanthera, 
Baoly=s; Crocosmia, Freesia, Gladiolus, and 
xia. 
T. capensis, 
T. miniata is a variety of 7. crocata. 
T. rosea (rosy). 
The correct name is Acidanthera capensis. 
jl. four to twelve in a loose spike; perianth 
bright red, lin. long, the tube broadly funnel-shaped, the 
segments oblong; spathe valves 4in. to Sin. long. June. 
/. linear, tirm, 1ft. long. Stems branched, 14ft. to 2ft. long. 
Corm globose, lin. in diameter. (B. M. 7280.) 
Varieties. Some of the best of the popular Montbretia 
section of this genus are: 
AURORE, BOUQUET PARFAIT, ELDORADO, ELEGANS, ETOILE DE 
FEU, FANTAISIE, GERBE D'OR, GOLDEN SHEAF, SOLFATERRE, 
SULPHUREA, TALISMAN, and 'TRANSCENDANT.
