foliis confertis sessilibus patulis subrecurvatis linearibus 

 basi dilatatis apice pungentibus margine valde revolutis 

 supra glabris subtus cano-tomentosis, capitulis terrain alibus

 Haplostephiura Passerina, Mart, in DC. Prodr. 5. p. 78. 

 Hab. Bushy places, Serro do Frio, Diamond District. Aug.

Frutex ramosissimus, 3-4-pedalis. Folia 4 lin. longa, vix 

 lineam lata. Corolla glabra, violacea. Achsenium obovatum, 

 glaberrimum, 10-costatum. Pappus duplex, paleis externis 

 brevissimis squamaeformibus obtusis albidis, intimis multo 

 longioribus linearibus acutis margine ciliatis spiratiler tortis 

 pallide violaceis. 



This plant I take to be the Haplostephium Passerina, Mart, 

 but a careful examination of it, and of two others which I 

 possess with a similar structure and habit, discloses no cha- 

 racter by which the genus can be separated from Lychnophora. 

 In the character given in the Prodromus the pappus is said 

 to be simple, and that is the only circumstance which dis- 

 tinguishes it from Lychnophora', but in all my three species I 

 find an external series in the shape of small obtuse scales, 

 distinctly obvious even to the naked eye, which must have 

 been overlooked both by Martius and Decandolle. Such 

 being the case, they must be placed in the first section of 

 Lychnophora along with L. rosmarinifolia, with which they 

 agree in habit, and in having one-flowered capitula. 

 4822. L. subulata; fruticosa, raraosa, ramis alternis vel 

 subverticillatis teretibus adpresse sericeo-tomentosis 

 demum glabriusculis, foliis confertis sessilibus erecto- 

 patentibus lineari-subulatis basi dilatatis apice pungentibus 

 margine valde revolutis supra glabris subtus cano-tomen- 

 tosis, capitulis terminalibus l-floris in glomerulum foliis 

 cinctum aggregatis, involucri squamis lineari-oblongis acutis 

 uninervibus extus tomentosis.
