FERNALD. GENUS PECTIS.

Hook. & Arn., and P. tenella, DC. (connecting this group with Pedis 

 proper) ; and P. papposa was described as new. 



In 1852 Dr. Gray ^ showed that Pedis angustifolia^ Torr. intergraded 

 with his own P. fastigiata^ and that with such evidence at hand both 

 De CandoUe's genus Pedidopsis and the species Pedis fastigiata were 

 untenable. As a provisional arrangement of species Dr. Gray ^ then 

 proposed the following : — 



Pappus coroniforrais, vel in disco vel in radio, et ssepius 1-4-aristatis : 

 Aristis sursum scabris v. nullis. (P. angustifolia, filipes, 



uniaristata, et sp. nov. Am. Merid.) Pectidopsis. 



Aristis cornels retrorsum hispidis. (P. Coulteri, multiseta.) Heteropectxs. 



Pappus uniformis, ex aristis paucis corneis Isevissimis. 



Pappus uniserialis, e paleis vel aristis basi paleaceo-dilatatis 



paucis. 

 Pappus biserialis paleaceus, in radio nunc dimidiato-a[u]ri- 



culseformis, nunc nullus. 

 Pappus setosus, 1-2-serialis, setis capillaribus basi vix aut 



ne vix dilatatis, in radio nunc dimidiato-auriculseformis. 



Pectidium. 

 eupectis. 

 lorentea. 

 Pectothrix. 



Following the suggestion that Lnrentea might well be united with 

 Pedis, Schultz Bipontinus ^ transferred to Pedis the Lorenteas of De 

 Candolie's Prodromus and of Hooker and Gardner, though his only new 

 species, P. Seemannii, afterward proved to belong in another genus.'' 



In 1853 Dr. Gray ^ made additional notes on some of the old species, 

 and described P. (Pedothrix) longipes and the anomalous P. imberbis. 

 And in 1858 Triana® described his genus Cheilodiscus, " Pappus coroni- 

 formis quinquedentatus, dentibus acutis persistentibus," with only one 

 species, C. litloralis, from New Granada. Apparently this belongs to 

 the section Pedidopsis. 



In 1861 Van HalH published P. febrifuga from Curasao. From the 

 excellent plate accompanying the description, this would seem to be 

 nearly related to P. capillaris. And since then a number of South 

 American and West Indian species have been published, but these need 

 not concern us here. 



In the Genera Plantarum, Bentham and Hooker * suggested that 

 further study was necessary to clear up Dr. Gray's sections Eupedis, 

 Pedothrix, and Lorentea.
