FLORA OF ADEN . 
white or violet, persistent for a long time ; segments equal, 1 inch long, 
3 lines broad, free from the base, lanceolate, attenuate from the middle 
into a claw ; claw involute, saccate at the base, margins fimbriate, near 
the base 2 fuscous, nectariferous auricles. Stamens 6, hypogynous, 
slightly longer than the perigone ; filaments subulate, erect ; anthers 
attached at or slightly below the middle ; loculi laterally dehiscent. 
Ovary oblong, sessile. Style undivided, thin, towards the tip slightly 
thickened, at the apex shortly tricuspidate into the recurved stigmas, 
erect, exceeding the anthers. 
Capsule 1 inch long, J inch broad, surrounded by the marcescent 
perianth, oblong, obtuse, subclavate, 3-dymous, loculicidally dehiscent j 
loculi 4 — 6-seeded. Seeds compressed, irregularly orbiculate, tV inch in 
diameter ; testa fuscous-yellow, glabrous, minutely punctulate under the 
lens. 
Flowers: — April 1884 (Defl.) ; Dec. 1883 (Yerbury). 
Locality : — Little Aden, plentiful on the trachytic debris at the foot 
of the last spurs of Jebel Ihsan (Defl.) ; on the sand (Yerbury). 
Distribution : — Yemen (Defl.). 
Note According to Defiers the point of insertion of the anther on 
the filament is not constant. The anthers are usually attached at the centre 
of the connective, sometimes considerably below the middle, towards the 
lower third, and more rarely the point of insertion is situated above the 
middle. The length of the style, too, is very variable. It usually ex- 
ceeds the stamens, but in certain flowers it scarcely reaches f of the 
length of the stamens. Defiers does not consider these differences as a 
case of normal heterostyly, but is more inclined to ascribe them to 
simple individual peculiarities of certain flowers. 
Littonia minor resembles very much L. Revoili Franch., but the 
following characteristic points mark it off as a distinct species s 
Verticillate arrangement of the lower leaves, different colour of the 
flowers, complete independence of the perianth segments of each other. 
Judging from the description, Krause considers it possible that 
Littonia Hardeggeri Ritter v. Beck is identical with Littonia minor 
Defl. The differences, indeed are not very great, and it seems that 
L. Hardeggeri can be distinguished only by its yellow flowers and slightly 
shorter stamens. ( Cf . Paulitschke, Harrar Forschungsreise, page 451, 
Ic. figs. 8, 9). 
Defiers discovered L. minor for the first time in 1884 on the penin- 
sula of Little Aden. On a later visit to the same place he could not find 
it; but in 1890 he came across the same species in the Hinterland of 
Yemen, about 60 km. west of Aden.
