130 PROCEEDINGS OF THE AMERICAN ACADEMY 



Var. y. LOB ATA ( Verhesina lohata, Gaud. V. hastulata, Hook. &, 

 Arn, Lipoch(Bta lohata ^ hastulata, DC.) : foliis subsessilibus vel bre- 

 viter petiolatis basim versus uti'inque lobatis seu laciniato-dentatis. 

 — Pappus, in all the forms of this polymorphous species, of 2 or 3 

 short chaffy awns or narrow scales. In all the species an epigynous 

 gland, at the base of style of the disk-flowers, fills the bottom of the 

 tube of the corolla. 



L. SUBCORDATA (sp. nov.) : herbacea? erecta, cinereo-strigulosa ; 

 foliis deltoideo-subcordatis acuminatis duplicato-serratis reticulatis longe 

 petiolatis, petiolis gracilibus ; involucri squaniis ovato-oblongis obtusi- 

 usculis. — Hawaii, on the coast. 



L. CALYCOSA (sp. nov.) : fruticosa, hispidulo-scabra ; foliis lanceo- 

 latis oblongisve obtusis obsolete subserratis vix triplinerviis brevissime 

 petiolatis ; involucri squamis 5-8 ovalibus seu obovatis obtusissimis 

 foliaceis discum subsuperantibus ; paleis receptaculi convolutis trunca- 

 tis. — Diamond Hill, Oahu. 



L. LAVARUM, DC. ( Verbesina lavanim, Gaud.) Well marked by 

 its silvery-canescent (but scarcely strigose) leaves, which vary from 

 narrowly to broadly lanceolate or oblong, the veins and triple ribs con- 

 spicuous beneath. Achenia all fertile, very variable (as in the other 

 species and in the manner of many Verbesinoid genera) as to the 

 wings, &c. The wings, when developed, are extended upwards into a 

 salient process as long as the pappus (which is of 2 or 3 stout, puberu- 

 Icnt, more or less clavate and blunt awns or palecc) but wholly free 

 from it. 



L. INTEGRIFOLIA {Microchceta integrifoUa, Nutt.) : herbacea e ra- 

 dice lignescente, humifusa, ramosissima, minutim sericeo-canescente ; 

 foliis subcarnosis parvis (pollicaribus) spathulatis linearibusque integer- 

 rimis, venis baud perspicuis ; pedunculis solitariis temiinalibus ; involu- 

 cri squamis biseriatis ovatis vel rotundis obtusissimis disco brevioribus ; 

 paleis receptaculi obtusissimis. — Oahu and Maui. Achenia generally 

 less winged than in the preceding. 



L. SUCCULENTA, DC. (which Rcmy has collected both upon Nihau 

 and Kauai), has the habit of Bclipta, and ranges between L. atistralis 

 and L. integrifolia. The leaves are not absolutely glabrous ; a lens 

 shows some minute strigose hairs. 



L. HETROPHYLLA (sp. nov.) : sufiVuticosa, ramosissima, erecta, aspero- 

 hispidula; foliis plerisque trifidis, segraentis oblongo-linearibus seu line- 

 ari-lanceolatis denticulatis nunc laciniatis vel inciso-pinnatifidis ; involu-
