\.p. 48, proves, from specimens with good fruit raised in the Cambridge Botanic Garden from seeds commu- 

 nicated by Lindheimer, to have a squamellate pappus, and therefore to be a second species of Halea. The 

 two species are thus characterized : — 



■/ 1. Halea Ludoviciana (Torr. fy Gray) : foliis amplis ovatis crebre et argutissime dentalis, superioribus 

 late connatis ; tubo corolla? glabra ; pappo e paleis ovalibus coriaceis circ. 20 latitudine achenii paulo brevi- 

 oribus. 



y 2. H. Texana : gracilis; foliis oblongis vel lanceolatis sinuato-pinnatifidis ; tubo corolla? glanduloso ; 

 pappo e squamellis subulatis exiguis ina;qualibus, majoribus vi.x dimidium latitudinis achenii aequantibus. — Dr. 

 Gregg also gathered this species at Mier, on the right bank of the Rio Grande. 



* Dr. Thomas C. Porter, of Pennsylvania, has furnished me with specimens of an ambiguous Helianthoid 

 plant, gathered by himself on Rock Mountain, Georgia, which I am unable positively to determine for want of 

 the fruit, but which I incline to refer to Rudbeckia, next to R. triloba, notwithstanding that the lower leaves 

 are opposite and the disk-flowers are yellow. It may be provisionally characterized as follows : — 

 •/ Rudbeckia? Porteri (sp. nov.) : caule gracili hirsutulo apice paniculato ; foliis membranaceis lanceola- 

 tis integerrimis utrinque acutis basi attenuata subsessilibus indistincte triplinerviis parce hispidis, superioribus 

 alternis inferne setigero-ciliatis, inferioribus oppositis ; pedunculis gracilibus 1 - 2-bracteatis monocephalis ; 

 squamis involucri biserialis exterioribus anguste linearibus foliaceis acutissimis laxis hispido-ciliatis disco lon- 

 gioribus, intimis paucis multo brevioribus oblongi-ovatis membranaceis glabris in cuspidem acuminatis paleis 

 receptaculi conici consimilibus ; ligulis aureis 7- 9 obovati-oblongis involucrum duplo superanlibus ; corollis 

 disci flavis profunde 5-lobis glabris ; styli appendicibus filiformi-subulatis hispidis ; ovariis calvis compressis 

 marginibus parce hispidulis. — Capitula iisdem R. triloba? minora.
