14 RECORDS OF OBSERVATIONS ON SIR WILLIAM MACGREGOR’S 
shorter, the uppermost very short, Headlets of flowers singly terminal. Involucral 
bracts about one eighth of an inch long, keelless. Receptacle flat. . Flowers not very 
numerous. Ligules of the marginal flowers about one sixth of an inch long, narrow- 
elliptic, entire, their colour in the dried state not ascertainable. Corolla of the bisexual 
flowers hardly one twelfth of an inch long. Fruits of the peripheric flowers dark- 
brown, about one tenth of an inch long. 
This singular plant is allied to one of the rarest in the world, the exclusively 
Italian Nananthea perpusilla. Generically it is different mainly in the fruits of the 
bisexual flowers not becoming perfected, and in the turgidity and curvature of the 
marginal achenes. Some approach to Aphanostephus is also noticeable. In 
reference to Allardia, which genus belongs to this series of the Composites, it might 
here be noted, that it has to give way to that of Waldheimia, which was published in 
1842, therefore two years earlier; thus the alteration of the names of four plants, all 
from the Indian Highlands, is involved. See on this subject also observations of mine 
in the Bulletin de la Société Impériale des Naturalistes de Moscou 1877, Append. p. 42. 
Senecio haplogynus. 
Robust, almost glabrous; leaves from ovate-to narrow-lanceolar, entire or 
imperfectly denticulated, the upper short-stalked or quite sessile, but never amply 
clasping ; headlets of flowers rather small, rayless, corymbously aggregated ; involucre 
twice as long as broad, its constituting bracts about eight ; accessory bracts only two 
or three, very short, acute; flowers in the headlets not numerous; several of the 
outer flowers estaminate, their corolla rigidulous, from a broadish base gradually much 
narrowed upwards and at their summit but slightly denticulated, their style often 
partly emerged with extremely short broadish and blunt stigmas; corolla of the 
bisexual flowers very slender except at and near their summit; anther-base lobeless ; 
style also almost undivided with the stigmas conspicuously dilated at the termination ; 
achenes thinly cylindrical, almost glabrous, few-streaked ; Pappy -bristlets numerous, 
very tender, subtile-capillary, denticular-rough. 
Summit of Mount Knutsford. 
Lower portion of the plant unknown yet. Upper leaves somewhat crowded, one 
to two inches long, acute. Inflorescence rather compact. Involucral bracts almost 
lanceolar, about a quarter of an inch long, but little over-reached by the flowers, in part 
scarious along the margin. Anantherous flowers sometimes outnumbering the bisexual 
flowers. Fruits slender, nearly one-tenth of an inch long ; length of pappus not much 
more. 
Bentham and J. Hooker observed already (gen. plant Il, 208), that occasionally 
some thin solely pistillate flowers occur in species of Senecio; hence the only 
characteristic, which separates Erechtites from that genus, is unreliable, and therefore 
the present plant may be placed into either genus. More of the aspect of a Senecio
