Trichodesma hockii

Perennial herb with 1-several erect stems up to 50(70) cm. from rootstock, usually unbranched except for the inflorescence but sometimes with few sterile axillary shoots; stems variously setose-pubescent with irregularly spreading soft setae and often softer smaller hairs interspersed, or occasionally subglabrous with sparse stiffer tuberculate setae, very rarely subglabrous throughout. Leaves (2)4–7(9) x (0.3)0.7–3(3.6) cm. or very rarely (exceptional leaves perhaps on sterile shoots) up to 16 x 5 cm., lanceolate to broadly ovate or elliptic, acute or obtuse at the apex, cuneate to rounded at the base, sessile, the lower ones opposite, the upper sub-opposite or alternate, regularly clothed on both surfaces by either flat tubercles with or without hairs or with short setose hairs with or almost without tubercles. Inflorescences 2–30 cm. long, with 2–9(12) primary branches each bearing 1 -8( 12) flowers; primary branches usually subtended by very reduced leaves but individual cymes ebracteate; pedicels 1–1.2(2.7) cm. in flower, elongating to up to 3.5(4.5) cm. in fruit, with spreading hairs often hooked upwards at the apex or occasionally with only upwardly appressed hairs which may be sparse. Sepals (10)12–16(18) x (3)5–8(9) mm. in flower, ovate, usually broadly overlapping each other and margins often curved outwards, enlarging to up to 20 mm. broad in fruit and then cordate at the base, clothed with sparse to dense hairs (tuberculate or not) either closely or loosely upwardly appressed in the upper part but often spreading or reflexed towards the base, rarely subglabrous with a line of tuberculate hairs round the margin. Corolla (15)17–25(3) mm. long, the lobes spreading or reflexed (in herbarium specimens usually obscuring the sepals in a majority of fully open flowers) and triangular with an acute apex, usually glabrous but rarely with a line of hairs down the middle of the lobes; lobes usually blue (? occasionally white), the tube usually white or cream and often (? always) with brown markings at the sinus between the lobes. Fruit as in T. physaloides.
