However, it differs from S. thomsonii in several characters which include: basal leaves spathulate-elliptic, apices obtuse in S. kashmirensis (vs. oblong-elliptic, apices sub-acute in S. thomsonii), base of cauline leaves usually free, or rarely connate up to 0.2–0.4 cm (vs. base connate, up to 1–2.5 cm), pedicel length 1.5–2.5 cm (vs. 3–5 cm), sepal apex acute (vs. sepal apex acuminate), petals yellowish, apices obtuse (vs. petals white, apices acute), size of nectaries 1.2–1.3 × 0.5–0.7 mm, oblong-oval (vs. 1.4–1.5 × 0.8–0.9 mm, elliptic-oval), fimbriae 3–5 per nectary, 2–3 mm long, restricted on lower part of the nectary towards base of the petal (vs.14–16 per nectary, 3–5 mm long, upright and arise all around the margin of nectary), anthers obovate, dorsifixed (vs. anthers ovate, sub-dorsifixed), capsule 8.5–9.5 × 5–7 mm (vs. 10–10.5 × 2–4 mm), seeds blackish, round-oblong (vs. brownish, oval-oblong).
