congestim corymbosis ; involucri squamis linearibus subacutis ; ligulis 

 plurimis brevissimis pappum uniserialem adjBquantibus stylis suis bi-e- 

 vioribus ; flore hermaphrodito sa?pius unico ; acheniis parce hirsutulis 

 2 - 4-costatis. — Sandwich Islands, on the sand-hills of Maui. — The 

 facial ribs of the achenia are often obsolete. If the species which con- 

 nect it with the original Tetramolopium were unknown, this would 

 surely be referred to the Ccenotus section ai Erigeron. 



Calotis palmata (sp. nov.) : hispido-pubescens ; foliis cuneatis 

 seu flabelliformibus palmato-3 - 5-fidis (nunc pedatifidis) inferne longe 

 quasi in petiolum alatura attenuatis basi leviter auriculatis, summis line- 

 aribus oblongisve integerrimis vel apice tridentatis ; involucro biseriali 

 fere 20-phyllo ; acheniis complanatis Icevibus ; pappo e paleis 2 - 4 et 

 aristis 1-2 versus apicem parce retrorsum aculeolatis. — Hunter's Eiver, 

 New South Wales. An herbaceous species, with larger heads than 

 those of G. dentex. Cunningham's G. dilatata has the awns of the 

 pappus similarly but more sparingly barbed ; but its leaves are not 

 lobed, and the basal auricles are more conspicuous. 



Lagenophora Pickeringii (sp. nov.) : foliis hirsutis primum 

 villoso-lanatis oblongis ovalibusque in petiolum attenuatis repando-den- 

 tatis ; scapo gracili nudo ; involucri squamis linearibus fere glabris ; 

 acheniis radii oblongo-lanceolatis erostratis insigniter costatis glaberri- 

 mis, disci sterilibus. — Mountains of Muthuata, one of the Feejee 

 Islands. Among the largest species of the genus, the scape 6 to 8 

 inches high, but the head is proportionally rather small, in fruit only 

 three lines in diameter. The achenia are coarsely striated by 8 or 

 10 strong and salient ribs (in a manner unknown in other species), 

 not beaked, but terminated by an epigynous disk about the size of the 

 basal callus. 



Aplopappus P<eppigianus, var. radiatus {Diplopappus Pceppi- 

 gianus, Hook. & Arn., forma eradiata. Aplopappus sericeus, Phi- 

 lippi) : humilis, fruticosus ; foliis secus ramos breves confertissimis 

 anguste lanceolatis rigidis utrinque attenuatis cuspidatis integerrimis 

 undique sericeis ; pedunculis elongatis nudis parce setaceo-bracteatis 

 monocephalis ; involucri hemisphaerici squamis lineari-subulatis glandu- 

 loso-puberulis, apicibus squarroso-patentibus ; ligulis discum vix super- 

 antibus ; acheniis sericeis. — Chili, on the Andes above Santiago. The 

 rigid, entire, silvery-silky, Protea-like leaves are crowded on the short 

 and tufted woody branches. Head rather larger than that of A. pul- 

 chellus.
