I do not find distribution of Deutzia compacta Craib in Nepal as per Catalogue of Life;

To me appears close to images at Deutzia staminea R.Br. ex Wall.

2. Deutzia compacta Craib, Kew Bull. 1913: 264 (1913).Deutzia corymbosa var. hookeriana C.K.Schneid.; D. hookeriana (C.K.Schneid.) Airy Shaw.

Shrubs 2–2.5 m. Stem 6–8-rayed stellate hairy, glabrescent. Petioles 2–3 mm. Leaves narrowly ovate to elliptic, 2–7.5 × 0.8–2.5 cm, base rounded to cuneate, apex acute to acuminate, margin serrulate, regularly 4–6-rayed stellate hairy above, hairs sometimes with erect central ray, more denselystellate hairy below, secondary veins 3–4 pairs. Inflorescences 2–8 cm, 8–15 flowered, terminal or on 4–6-leaved flowering branchlets, axes rather sparsely stellate hairy. Pedicels 3–15 cm. Flowers ca. 1 cm across. Calyx tube cupular, stellate hairy, teeth broadly ovate, 1.5–2 × 1.5–2.5 mm. Petals white to pink or purplish, imbricate, obovate to ovate or suborbicular, 6–7 × 5–6 mm, stellate hairy outside, glabrous within.

Distribution: Nepal, E Himalaya, Tibetan Plateau, Assam- Burma and E Asia.

Altitudinal range: 2100–3900 m.
Ecology: Riversides and alpine scrubland.Flowering: April–June. Fruiting: June–September.

Clarke (Fl. Brit. Ind. 2: 406. 1878) partially misapplied Deutzia corymbosa R.Br ex G.Don to this species.

Noshiro et al. 9840077 (TI, E), collected in fruit from Sankhuwasaba, was previously determined as D. compacta, but its flowers have 5 or 6 styles and it has larger leaves (to 9 × 4 cm) whose underside have an even indumentum of stellate hairs with long, erect central rays. It appears not to match any Himalayan species, but the material is not complete enough to be certain that it is a new species.

Thanks, Saroj ji,

From where these details have been taken ?

Going by the calyx as per following illustrations of both the species, it should be Deutzia staminea R.Br. ex Wall.

Hi, Saroj ji,

Pl. see discussions at Anil ji's thread at Deutzia corymbosa

In view, we may take your plant as Deutzia compacta Craib as per details forwarded by you in this thread.

Keys given in Flora of Nepal and those in Anil ji's thread appear confusing.

I think keys based on Anil ji's thread w.r.t. the size of the leaves (large for D.corymbosa- which is rare) and appearance of the lower surface (green for D.corymbosa) appear more convincing.

For synonyms we can follow Deutzia corymbosa R. Br. as a syn. of Deutzia hookeriana (Schneid.) Airy Shaw as per Catalogue of life (S-Tibet, China (NW-Yunnan), Bhutan, Sikkim, Myanmar [Burma] (Kachin), Nepal, Jammu & Kashmir (Kashmir), N-India)

Checklist of Nepal gives Deutzia hookeriana (C. K. Schneid.) Airy Shaw as a syn. of Deutzia compacta Craib (S-Tibet, China (NW-Yunnan) as per Catalogue of life).

In view, we may take this plant as Deutzia staminea only.
