310 Notes on Indian Botany. 



scariose, interior ones connivent or radiant: receptacle flat 

 epaleaceous, naked, areolate or fimbriliferous : involucra 

 white, purple, or yellow : corolla yellow or purple. 



61. Gnaphalium, (Don. D.C. 6-221). Capitulum hetero- 

 gamous, flowers all tubular, marginal ones, many series, 

 female ; disk ones hermaphrodite : achsenia somewhat terete, 

 subpappillose : pappus 1 -series, scarcely rough. Herbace- 

 ous or suffruticose, generally woolly or tomentose plants, 

 capitula often disposed in glomerulus, terminal or axillary, 

 fascicled, corymbose, or spicate : involucra white, red, purple 

 or yellow. 



62. Filago, (Tourn. D. C. 6-247). Capitula heterogamous, 

 marginal flowers numerous, on an elongated filiform recepta- 

 cle, the apex only dilated and bearing a few male or herma- 

 phrodite flowers : achsenia terete papillose : pappus of the cen- 

 tral ones, setose filiform, of the margin wanting or dissimi- 

 lar. Tomentose herbs : capitula axillary or aggregated on the 

 ends of the branches, small. [There is a descrepancy 

 between this generic character and that of F. prostrata, the 

 central florets of that species being without pappus, the 

 marginal ones having it : neither do I find palese on the 

 receptacle of that species.] 



63. Antennaria, (Brown D. C. 6-269). Capitula dioicous 

 or subdioicous, with an alveolate convex receptacle ; female 

 flowers filiform 5-toothed ; male, anthers half exserted : 

 achaenia terete : pappus 1 -series, setae of the female flowers 

 filiform, of the male clavate. Herbaceous or suffruticose: 

 capitula corymbose : involucrum imbricated, variously colour- 

 ed at the apex or scariose, never yellow : flowers yellow. 



64. Anaphalis, (D. C. 6-271). Capitula heterogamous 

 discoid ; marginal flowers few or many series female ; disk 

 ones hermaphrodite sterile 5-toothed : styles of the marginal
