FLORA OF ADEN .

This new name was adopted by Knntze in his Rev. Gen. PI. I, 
358, in preference to the one ( Pulicaria iphionoides ) which he 
himself had chosen at an earlier date. Kuntze retained Schweinfurth's 
name because Schweinfurth's specimens had been distributed under that 
name in the meantime. Schweinfurth, however, had given it the specific 
name f adenensis 1 instead of Anderson's f arabica ' because there existed 
already a Pulicaria arabica Cass. 
Oliver and Hiern, when describing in the Trans. Linn. Soc. voh 
XXIX, p. 96 (cf. etiam Oliver, FI. trop. Afr. Ill, 365) their new 
species Pulicaria Grantii , added a note saying : “ Identified, perhaps 
incorrectly, with the plant called by Dr. Anderson, in his f Florula 
Adenensis/ p. 22, Vartliemia arabica (non Boiss.) under which name it 
occurs in App. Speke's Journ. 638.'’— Anderson's plant is not identical 
with Pulicaria Grantii . The latter has much longer and stouter ped- 
uncles which become considerably thicker towards the apex, and the 
capitula are larger. 
Krause (Engl. Bot. Jahrb. XXXV, Heft 5, p. 56) who has not seen 
Anderson's plant, considers it to be identical with Pulicaria glutinosa 
Jaub. et Spach. In this I followed him in my * Flora of Aden' (Journ. 
Bombay Nat. Hist. Soc. vol. XVII, p. 907, n. 95), but after having 
examined the type specimens, together with the other specimens at Kew, 
I came to the conclusion that Anderson's plant is a distinct species. 
6. Diconia Cass. 
Herbs or low shrubs. Leaves alternate. 
Heads subsessile on the branches or in the axils of the upper 
leaves, or leaf-opposed, rarely corymbose, homogamous, discoid, 
all the flowers hermaphrodite ; or heterogamous, the outer 
flowers being female, all fertile or the innermost sterile. Involucre 
globose, conic or subcampanulate ; bracts oo-seriate, imbricate, ovate, 
lanceolate or linear, acuminate, spinescent or mucronate or with a long 
apical spine, the outer bracts gradually shorter. Receptacle flat, 
naked, often pitted. Corollas of hermaphrodite flowers tubular, 
the limb enlarged, 5 -partite, with erect or revolute lobes ; corollas 
of female flowers, if present, slender, subligulate. Anther-bases 
sagittate ; tails long, more or less bearded. Style-arms short, erect, 
obtuse. Pappus-hairs cc-seriate, the inner or all flat, barbellate or 
feathery, the outer shorter, paleaceous or of slender bristles. 
Achenes turbinate, densely silky -villous, 5— 10-ribbed.
