cymbfeformes, in cuspidern apice uncinatara rigidam sensim acuminatfe, 

 persistentes, fructu delapso stellato-patentes. Pappus nuUus. — Herba 

 exigua, digitalis, annua, Filaginis Gallicce facie ; foliis linearibus alter- 

 nis, summis capitulum vel glomerulum 3 - 4-cephaluin sessile involu- 

 crantibus. 



Ancistrocarphus filagineus. — Dry hillsides. Round Valley, 

 Eel River, Mendocino Co., May, Bolander. Stems simple or sparingly 

 branched, slender, 2 to 4 inches high. Leaves narrowly spatulate- 

 linear, clothed as is the whole plant with light flocculent wool. Paleae 

 of the fertile flowers arachnoid-woolly, especially towards the involute 

 margins, those of the sterile flowers fully twice larger, becoming 

 nearly two lines long, more naked, the hooked tips prominent, making 

 the head or glomerule squarrose. To provide for this little plant I am 

 obliged to add yet another to the Micropoid genera. This is related on 

 the one hand to Nuttall's Psilocarphus, of which it has the achenia and 

 the enclosing fructiferous paleae ; on the other to Hesperevax caulescens 

 (which may be completely separated from Evax, to which I referred 

 it in Bot. Whipp., p. 45, t. 10), having like that a whorl of coriaceous 

 palefB surrounding the sterile flowers. One would like to combine 

 these last ; but the habit does not invite it, and the naked fertile paleae 

 of Hesperevax are open as in Evax, although apparently persistent. 



Balsamorhiza Bolanderi: glulinosa, fere glabra; caulibus (sub- 

 pedalibus) e caudice longo adsurgentibus superne 3 -5-foliatis mono- 

 cephalis ; foliis omnibus petiolatis ovatis subrotundisve sfepissirae leviter 

 cordatis acuminulatis integerrimis ; capitulo maximo ; involucro duplici, 

 exteriori foliaceo 6 - 8-phyllo, phyllis ovatis oblongisve acutis disco longi- 

 oribus, interiori e squamis uniseriatis lanceolatis supra medium villosissi- 

 mis paleis receptaculi similibus ; acheniis (compressis vel obcompressis) 

 obovato-oblongis glabris areola epigyna parva. — Shady hillsides, at 

 Auburn, April, 1865, Bolander. " Rootstocks large ; whole plant 

 glutinous and of a strong resinous smell." The aspect of this remarkable 

 species is that of a Wyethia. Radical and cauliue leaves alike (2 to 

 4 inches long, on petioles of 6 to 20 lines in length), but the base of 

 the stout stems bears one or two scales in place of foliage ; the upper- 

 most leaf near the head or an inch or two below. Head in the dried 

 specimens 2 inches in diameter ; the yellow rays 12 or more, an inch 

 and a half long, broad. Achenia remarkably flattened for the genus. 

 [This, as now appears, was collected in 1844 by Fremont on the upper 

 Sacramento, and later by Major Rich.]
