144. HARPJECARPUS. Nutt. in trans. Amer. phil. soc. I. c. p. 389. 



Heads few-flowered ; the ray-flowers 5-8, pistillate, in a single series, each 

 enclosed in one of the carinate-complicate and lunate scales of the involucre ; 

 the disk-flower solitary ! tubular and perfect, fertile, surrounded by a 5-angled 

 and 5-toothed cup, consisting of the united chaff" of the receptacle. Corolla 

 glabrous ; of the disk -flower infundibuliform, 5-toothed ; of the rays scarcely 

 exceeding the involucre, tubular below, cleft above anteriorly ; the very short 

 and broad ligule 2-3-toothed or lobed, about the length of the linear glabrous 

 branches of the style. Branches of the style in the disk-flower short, lance- 

 olate-oblong, with barbellate-hispid margins. Achenia glabrous, much com- 

 pressed, destitute of pappus ; of the rays gibbous, obovate-lunate, the incurved 

 summit produced into a short ascending beak, when mature deciduous with 

 the scales of the involucre that enclose them ; that of the disk semi-obovate, 

 straight, with a truncate terminal areola, included by the united chaff". — A 

 small slender hirsute annual (3-12 inches high), with somewhat the aspect 

 of a Myosotis; the erect simple stem clothed with mostly alternate narrowly 

 linear and entire leaves, corymbose-paniculate at the summit, bearing sev- 

 eral small heads on simple and naked peduncles, which are elongated in fruit. 

 Flowers pale yellow, very small. 



H. madarioides (Nutt. ! 1. c.) — Sclerocarpus exiguus. Smith, in Rees, cycl. 

 (ex char. & descr. Hook. Sf Am. hot. Beechey, suppl. p. 355, under Madaria

Oregon (' North West Coast,' doubtless collected by the venerable Menzies, 

 if we are right as to the synonymy) : common on rocky plains in depressions 

 at the outlet of the Wahlamet, Nuttall ! May. — Leaves about an inch long, 

 less than a line wide. Peduncles filiform and often 2 inches long in fruit, 

 bearing a depressed-globose head scarcely 2 lines in diameter. Involucre 

 covered with stipitate glands and short hispid hairs intermixed. Plant some- 

 what aromatic. 



Subtribe 6. Anthemideje, Cass., DC. — Heads mostly heterogamous 

 (never dioecious) ; the ray-flowers in one or more series, pistillate or rarely 

 neutral, either ligulate or tubular ; the disk-flowers perfect or sometimes 

 staminate and infertile. Receptacle naked or chaffy. Anthers not caudate. 

 Branches of the style truncate and mostly bearded at the apex, very rarely 

 produced into a short cone. Pappus small and coroniform, or usually 

 none. — Leaves mostly alternate.
