BY B. F. BUSH. 



Antennaria ampla n. sp. Folia caulium sterilium 4-5 cm. 

 lata, 5-10 cm. longa, (petiolos tenues includentia), primo villoso- 

 tomentosa facie superiore cito glabra, inferiore qiiidem dense 

 flaveo-tomentosa. Planta fertilis caulibus 3-4 dm. altis, tenuibus, 

 laxe tomentosis cum foliis 8-12 oblongis, acutis, 1-3 cm. longis. 

 Capitula pauca, minuscula, subsessilia in summitate pedunculi 

 insita. Bractcae involucri permultae in 2-3 seriebus; interiores 

 vero longiores, angustiores et aciitae, exteriores quidem apice 

 denticiilato, et ambae ad apicem scariosae. Planta staminea 

 caulibus .5-1.5 dm. alta laxe tomentosa, cum 5-8 foliis anguste 

 oblongis acutis. Capitula pauca in summitate pedunculi capitata; 

 bracteis paucis in 2-3 seriebus, exterioribus oblongis, et brevioribus 

 quam in interioribiLS, quae late oblongae aliquamtulum dilatatae, 

 majores, et ad apicem denticulatae singulariterque scariosae sunt. 

 Pappus ad apicem aliquantulum dilatatus et serratus. 



Antennaria ampla n. sp. Leaves of the sterile shoots ample, 

 4-5 cm. broad, 5-10 en), long, including the slender petioles, at 

 first villous-tomentose above, soon glabrous, below densely yellow- 

 ish-tomentose. Fertile plants with stems 3-4 dm. tall, slender, 

 loosely tomentose, with 8-12 oblong, pointed leaves, 1-3 cm. 

 long; heads several, rather small, subsessile at the top of the 

 stems; involucral scales numerous, in 2 or 3 series, the inner 

 longer, narrower, and acute, the outer broader, shorter, and 

 denticulate at apex, all showily scarious at tips; male plants with 

 stems yi-^Yi dm. tall, loosely tomentose, with 5-8 narrowly- 

 oblong pointed leaves; heads several, in a capitate cluster at 

 top of stems; involucral scales few, in 2 or 3 series, the outer 

 oblong, shorter than the inner, the inner broadly oblong, some- 

 what dilated, larger than the outer, denticulate at apex, the upper 

 portion showily scarious; pappus-tips slightly dilated, serrate. 

 This species was discovered by myself, in compan}- with Misses 

 Martha and Pearl Julian, and my two daughters. May and Hazel, 

 on May 22, 1914, No. 71 19. 



The precise locality where this species was found is about
