cri squamis late ovatis sfepius acurainatis disco parum brevioribus ; 

 paleis receptaculi mucronatis. — Folia 1 - 3-pollicaria, nunc petiolata 

 petiolis marginatis, nunc connato-amplexicaulia. — Maui. Pappus of 

 2 or 3 very short and squamellate awns or paleas, which are somewhat 

 coroniform concreted at their base. 



L. TENUiFOLiA (sp. nov.) : herbacea, erecta, gracilis, fere glabra : 

 foliis pinnatipartitis, segmentis rhachique angustissime lineai'ibus seu 

 filiformibus integerrimis ; involucri squamis lanceolatis discum adae- 

 quantibus ; paleis receptaculi acutatis. — Oahu. The achenia are 

 2 - 4-angled, their angles sometimes slightly winged, or produced at 

 the summit ; and the pappus consists of 2 to 4 short and somewhat de- 

 ciduous awns. 



L. (Aphanopappus) micrantha {ScMzophyllum micranthum, Nutt. 

 Aphanopappus Nuttallii, Walp.) : herbacea, minutim strigulosa ; cauli- 

 bus gracillimis ramosissimis diffusis ; foliis tenuibus bi — tripinnatipar- 

 titis, segmentis parvis subcuneatis saepe bi - trilobatis ; capitulis parvis 

 breve pedunculatis ; involucri squamis exterioribus lineari-spathulatis 

 laxis, interioribus oblongis ; ligulis 2-3 ovalibus ; fl. disci 6 - 8 ; ache- 

 niis apteris ; pappo obsolescente. — Kauai (Atooi). Ovaries pubes- 

 cent at the summit, as in Lipochceta generally, the short hairs, or part 

 of them, apparently forming a minute coronulate pappus, of which only 

 mere vestiges remain upon the mature short-obovate achenium. The 

 exterior achenia are the most fertile, and turgid, 3 -4-angled ; the inner 

 more compressed or lenticular ; the central ones by no means always 

 infertile. 



L. (Aphanopappus) Remyi (sp. nov.) : herbacea, ramosissima, 

 diffusa, cinereo-hirsuta ; foliis oblongis petiolatis obtusis stepius parce 

 dentatis vel sublobatis, superioribus alternis ; capitulis parvis sub- 

 paniculatis breviter pedunculatis ; involucri squamis oblongis obtusis ; 

 ligulis 5-7 obovatis brevibus ; acheniis radii praesertim ad angulos 

 tuberculatis vel interrupte subalatis, disci inanibus ; pappo obsoleto. — 

 Oahu, Remy, no. 260. 



L. (Aphanopappus) laricifolia. Macrcea laricifoUa, Hook. f. 

 Trigonopterum Ponteni, Anders. — Galapagos Islands. 



GuNTHERiA Megapotamica, Sprcng. PolypteHs Brasiliensis, 

 Less, in Linnaea. Cercostylis Brasiliensis, Less. Syn. Compos. Spren- 

 gel's name for the genus, founded like Lessing's upon Sellow's speci- 

 mens, and revived by Schlechtendal (Linnaea, 11, p. 4), is the earlier by 

 several years, and nothing stands in the way of its restoration. The
