212 Dr. J. D. Hooker's Enumeration of the Plants 



longe attenuata, utrinque sericeo-pubescentia, marginibus integerrimis subrecurvis, sub- 

 tus reticulatim venosa ; petiolis brevibus, \ unc. longis, pulcherrime pilis albidis sericeo- 

 villosis. Pedunculi inter folia omnino occlusi, breves, dense sericei. Capitula magna, 

 I unc. diametro, subsessilia, depresso-globosa, multiflora. Involucri squamae foliaceae, 

 floribus bis longiores, anguste lanceolatae, attenuate, valde inaequales. CoroUae tubus 

 puberulus ; antheris fere omnino exsertis. 



This, in the form of the leaf, resembles S. atracty hides, 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.Jil.; pubcsceus, ramis validis supremis folio- 

 sis, foliis petiolatis ovatis ovato-lanceolatisve acuminatis utrinque atte- 

 nuatis serrulatis in petiolum decurrentibus, pedunculis gracilibus solitariis 

 petiolo eequilongis, capitulis parvis radiatis cylindraceis. 



Hab. Albemarle Island, Mr. Macrae. 



Rami robusti, pubescentes, crassitie pennse olorinae, tuberculis subannulatis notati, furcati ; 

 ultimi elongati, saepe hirsuti, undique foliosi. Folia patentia, inferiora reflexa, 3 unc, 

 longa, acuminata, subundulata, basi cuneata, supra moUiter pubescentia, venis obscuris, 

 subtiis sericea v. hirsuta, seniora venis prominulis rugosa, petiolis 1 unc. longis, latius- 

 culis, pubescentibus. Pedunculi graciles, axiUares, petiolo longiores, piloai. Capitula 

 parva, inconspicua, sub y unc. longa, cylindracea, longiora quam lata, siccitate nigres- 

 centia. Involucri squamae erectae, oblongas, obtusae, extiis puberulse. Coroilae radii 

 ligulati, l-seriales, disci tubo elongato glaberrimo; ligula suberecta, oblonga, multi- 

 nervi ; achaenio 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. ScALESiA AFFiNis, Hook.Jil.; pubcsccus, foliis ovatis acuminatis in pe- 

 tiolum brevem gradatim attenuatis serratis subtus hirsutis, pedunculis 

 gracilibus petiolo multo longioribus, capitulis radiatis majusculis cam- 

 panulatis. 



Hab. Charles Island, Charles Darwin, Esq, 



S. ffummi/ereB simillima, sed differt praecipue foliorum petiolis brevibus v. subnullis, capitu- 

 lisque duplo raajoribus latioribus campanulatisque.
