longé attenuata, utrinque sericeo-pubescentia, marginibus integerrimis subrecurvis, sub- 
tùs reticulatim venosa ; petiolis brevibus, + unc. longis, pulcherrimé pilis albidis sericeo- 
villosis. Pedunculi inter folia omnino occlusi, breves, densé sericei. Capitula magna, 
l unc. diametro, subsessilia, depresso-globosa, multiflora. Involucri squame foliaceze, 
floribus bis longiores, anguste lanceolate, attenuate, valdé inequales. Corollz tubus 
puberulus; antheris feré omnino exsertis. 
This, in the form of the leaf, resembles S. atractyloides, but in other respects 
is a perfectly different plant. The large capitula, white silky pubescence, and 
its imparting a character to the landscape of James Island, render the present 
species one of the most interesting of this singular genus. 
165. ScALESIA GUMMIFERA, Hook, fil.; pubescens, ramis validis supremis folio- 
sis, foliis petiolatis ovatis ovato-lanceolatisve acuminatis utrinque atte- 
nuatis serrulatis in petiolum decurrentibus, pedunculis gracilibus solitariis 
petiolo zequilongis, capitulis parvis radiatis cylindraceis. 
Hab. Albemarle Island, Mr. Macrae. 
Rami robusti, pubescentes, crassitie pennz olorinz, tuberculis subannulatis notati, furcati ; 
ultimi elongati, sæpè hirsuti, undique foliosi, Folia patentia, inferiora reflexa, 3 unc. 
longa, acuminata, subundulata, basi cuneata, suprà molliter pubescentia, venis obscuris, 
subtüs sericea v. hirsuta, seniora venis prominulis rugosa, petiolis 1 unc. longis, latius- 
culis, pubescentibus. Pedunculi graciles, axillares, petiolo longiores, pilosi. Capitula 
parva, inconspicua, sub 5 unc. longa, cylindracea, longiora quam lata, siccitate nigres- 
centia. Involucri squamze erectze, oblonge, obtuse, extüs puberule. Corolle radii 
ligulati, 1-seriales, disci tubo elongato glaberrimo; ligula suberectá, oblongà, multi- 
nervi; achznio elongato, calvo, angusto, 3-costato; flores disci ut in congeneribus. 
The specific name is suggested by the gummy exudation on this plant, but 
which is perhaps more or less common to the whole genus. 
166. Scaesia arriNIS, Hook. fil.; pubescens, foliis ovatis acuminatis in pe- 
tiolum brevem gradatim attenuatis serratis subtüs hirsutis, pedunculis 
gracilibus petiolo multó longioribus, capitulis radiatis majusculis cam- 
panulatis. 
Hab. Charles Island, Charles Darwin, Esq. 
S. gummifere simillima, sed differt praecipué foliorum petiolis brevibus v. subnullis, capitu- 
lisque duplà majoribus latioribus campanulatisque.
