MNPS Threat Rank
Perennial with a branched caudex. Stems erect, 3–20 cm. Herbage strigose, hispid. Leaves basal and cauline, petiolate, linear-oblanceolate, acute, 1–6 cm long, becoming sessile above. Inflorescence leafy-bracteate below. Flowers: calyx hirsute, hispid, 5–8 mm long in fruit; corolla 5–9 mm long, 6–8 mm across the limb; fornices ochroleucus. Nutlets 1 to 4, ovate to lance-ovate, ridged-rugose, 2–3 mm long; scar closed. (Lesica 2012. Manual of Montana Vascular Plants. BRIT Press. Fort Worth, TX)
Cryptantha macounii has been separated from Cryptantha spiculifera based on the length of the nutlets (Lesica et al. 2012). The length of the nutlets is continuous and varies within a population; therefore, Lesica et al. (2012) has chosen to retain the name of C. spiculifera. However, if the two taxa are officially separated then the Montana plants would be C. macounii.
