FERNALD, — GENUS PECTIS. 63 
Hook. & Arn., and P. tenella, DC. (connecting this group with Pectis 
proper) ; and P. papposa was described as new. 
In 1852 Dr. Gray ! showed that Pectis angustifolia, Torr. intergraded 
with his own P. fastigiata, and that with such evidence at hand both 
De Candolle’s genus Pectidopsis and the species Pectis fastigiata were’ 
untenable. As a provisional arrangement of species Dr. Gray? then 
Proposed the following : — 
Pappus coroniformis, vel in disco vel in radio, et seepius 1—4-aristatis : 
Aristis sursum scabris v. nullis. (P. angustifolia, filipes, 
uniaristata, et sp. nov. Am. Merid.) PectTipopsis. 
Aristis corneis retrorsum hispidis. (P. Coulteri, multiseta.) HETEROPECTIS. 
Pappus uniformis, ex aristis paucis corneis levissimis. PECTIDIUM. 
Pappus uniserialis, e paleis vel aristis basi paleaceo-dilatatis 
paucis. EvuprEctis. 
Pappus biserialis paleaceus, in radio nune dimidiato-a[u Jri- 
culetormis, nune nullus. LORENTEA. 
Pappus setosus, 1-2-serialis, setis capillaribus basi vix aut 
ne vix dilatatis, in radio nunc dimidiato-auriculeformis. PECTOTHRIX. 
Following the suggestion that Lorentea might well be united with 
Pectis, Schultz Bipontinus? transferred to Pectis the Lorenteas of De 
andolle’s Prodromus and of Hooker and Gardner, though his only new 
Species, P, Seemannit, afterward proved to belong in another genus.‘ 
In 1853 Dr. Gray * made additional notes on some of the old species, 
and described P. (Pectothrix) longipes and the anomalous P. imberbis. 
nd in 1858 Triana ® described his genus Oheilodiscus, “ Pappus coroni- 
; formis quinquedentatus, dentibus acutis persistentibus,” with only one 
_ Species, C. Littoralis, from New Granada. Apparently this belongs to 
} the section Pectidopsis. 
In 1861 Van Hall? published P. febrifuga from Curacao. From the 
q *xcellent plate accompanying the description, this would seem to be 
_ ‘hearly related to P. capillaris. And since then a number of South 
merican and West Indian species have been published, but these need 
; ot concern us here. 
n the Genera Plantarum, Bentham and Hooker ® suggested that 
r study was necessary to clear up Dr. Gray’s sections Hupectis, 
ectothrix, and Lorentea.
