gerentes, crispato-pilosi. Folia basi imbricata, longe petiolata, late 
oblanceolata vel obovato-oblanceolata, apice conspicue mucronata, 
basin versus sensim attenuata, 1-5 — 3 cm. longa, 1 — 1-5 cm. lata, 
mucronato-dentata, coriacea, utrinque crispato-pilosa et dense foveo- 
lata; petioli straminei, subalati, circiter 1-5 cm. longi, parce pilosi. 
Capitula axillaria, sessilia, circiter 1-3 — 1-5 cm. longa, interne ovoidea, 
medio constricta, 0-5 cm. diametro. Involucri bracteae purpurascentes, 
4 — 5-seriatae, apice in appendicem subulatam, 3 — 4 mm. longam 
attenuatae, parce pilosae. Corollae tubus anguste cylindricus, 5 mm. 
longus, parce puberulus; lobi lineares, acuti, 0-1 cm. longi, extra parce 
pubescentes. Achaenia anguste obovoidea, 0-3 cm. longa, albo-sericea. 
Pappi squamae 10, biseriatae, exteriores rotundatae, tenuissimae et 
hyalinae, apice undulato-dentatae, interiores in setam brevem scabri- 
dulam prolongatae. 
South-West Africa: North of Aintsas, in sand, Dec., H. H. W. Pear- 
son (Percy Sladen Memorial Expedition, No. 9240); between Tsondab 
and Great Fish Rivers, on shale slopes, common, Dec., id. [id. No. 9294). 
This is a very distinct species with broader leaves than any described 
hitherto ; the pappus scales when dry are remarkably thin and delicate 
as shown under a high power lens. 
Helichrysum viscidissimum, Hutchinson ( Compositae-lnuleae ). 
Planta circiter 18 cm. alta, multo ramosa, ramis dense albo-lanatis 
foliatis. Folia spatulato-oblanceolata, obtusa vel subacuta, ad basin 
longe attenuata, usque ad 1 cm. longa et 3 mm. lata, coriacea, utrinque 
glandulis breviter stipitatis dense viscidissima, 1-nervia. Capitula 
ter m in ali a, solitaria, foliis superioribus suffulta, plus minusve cam- 
panulata, circiter 0-8 cm. longa. Involucri bracteae parte superiore 
patulae vel recurvatae, albae, lanceolatae, acutae, extra interne 
glandulosae, superne glabrae, interiores lineari-oblanceolatae, glabrae. 
Flores circiter 30; corollae tubus anguste cylindricus, glaber. Achaenia 
turgida, brevissima, glandulosa. Pappi setae numerosae, albae, corollas 
superantes, minute barbellatae. 
South-West Africa: Naukluft Mts., below Goas, river-bed of ravine. 
Dec., H. H. W. Pearson (Percy Sladen Memorial Expedition, No. 9066). 
This species belongs to the group Leptolepidea, Moeser (Engl. 
Jahrb. xliv, 300), and appears to be most closely related to H. ceras- 
tioides, DC., differing in its densely glandular (not woolly) leaves and 
smaller capitula; another near ally is H. spiciforme, DC., with the 
capitula arranged in close leafy spikes. 
Plumbago Pearsonii, L. Bolus (Plumbagineae) , habitu P. tristis, Ait., sed 
facile distinguitur foliorum circumscriptione, calyce dissimili, ceterisque. 
Fruticulus erectus subrigidus, 25 — 30 cm. altus, ramis \iigati-
