A new golden rod from Northern New Mexico 



T. D. A. CoC KEKELL AND D. M . ANDREWS 



The plant described below was found in some abundance by 

 D. M. Andrews on rocky slopes of Mount Capulin National 

 Monument, New Mexico, where it appeared to favor the driest 

 positions. When transferred to the moister garden it retained 

 essentially its natural habit, but the inflorescence became some- 

 what more ample in its branching. 



/ Solidago capulinensis n. sp. 



Caulis 8.5 dm., multicephalus, erectus, strigosus, rugosus, 

 purpurascens; rami laterales numerosis; foliis lanceolatis, al- 

 ternis, viridibus, paucedentalis, numerosis; capitulis long. prox. 

 5.5 mm., lat. 3.5; phyllariis subacutis, viridimaculatis; acheniis 

 quinquecostatis, glabris. 



Erect, about 8.5 dm. high, with several to many strong 

 stiff stems from a compact crown, the very short runners from 

 base of stems being nearly erect; stems rough, striate, and 

 sufTused with purplish; radical leaves spatulate or oblanceolate, 

 10-15 cm. long, 2 cm. or more in width, broadly acute or 

 rounded at the tip, pinnate-veined, serrate above the middle, 

 entire and narrowing toward the base, the whole margin of the 

 leaf ciliate with curved hairs; cauline leaves sessile, alternate, 

 lanceolate, rough but not canescent, remotely dentate beyond 

 the middle, the margins very briefly ciliolate with minute 

 curved hairs; inflorescence spreading, with many axillary 

 branches, but not at all flat-topped, heads densely crowded; 

 heads about 5.5 mm. long and 5 wide, the phyllaries in about 

 three rows, appressed, rather obtusely pointed, whitish, with a 

 large lanceolate green mark at upper end, having for its stem 

 the narrow green midrib; pappus white, about 3.5 mm. long; 

 corolla bright orange, about 5 mm. long. At maturity the slender 

 glabrous achenes become about 3 mm. long, and are strongly 

 5-ribbed. The phyllaries exhibit a faint striation or ribbing, 

 hardly apparent after drying, whereas those of Oligoneuron 

 rigidum (L.) have five parallel pale green lines. The plant differs 

 greatly from 0. rigidum and its immediate allies in not having 

 the inflorescence at all flat-topped, and the heads smaller. In 

 contrast with 0. rigidum, the leaves are bright green, much
