請恕在下未問準Sanco前取用照片以茲說明
圖中藍線應為主幹,可看出"葉1-2回二歧深裂",FoHK描述為"0.5–1.5 cm long, unbranched or dichotomously divided into a few capillary segments"
而#1的照片可以看出"葉先羽狀深裂,後1-4回二歧深裂",FoHK描述為"2–8 cm long, pinnately divided, each pinna dichotomously divided into numerous capillary segments"
#1的照片可作判辨兩者之用。
以下為抄錄自FoHK的段落以便討論。
少花狸藻
U. gibbaFloating small herbs, with filiform, branched stolons seldom above 5 cm long. Leaves all submerged and root-like, alternate on stolons, 0.5–1.5 cm long, unbranched or dichotomously divided into a few capillary segments. Traps lateral on leaf segments, ovoid, 1–2.5 mm, stalked. Scapes slender, 5–10 cm, bearing a raceme of 1–2(– 3) flowers; scales 1, similar to the bracts; bracts basifixed. Pedicels erect or spreading, 2–12 mm. Calyx bilobed nearly to the base; lobes broadly ovate to suborbicular, subequal, 1.5–2 mm. Corolla yellow, 4–8 mm long, upper lip orbicular or broadly ovate, about twice the length of upper calyx-lobe, apex obscurely 3-lobed, lower lip slightly smaller; the spur conical, as long as the lower corolla-lip, or slightly longer. Ovary ovoid; style distinct. Capsule globose, 2–3 mm in diam., opening by valves.
黃花狸藻
U. aureaFloating small herbs, with filiform, branched stolons, extending to 30 cm or longer. Leaves all submerged and root-like, alternate on stolons, 2–8 cm long, pinnately divided, each pinna dichotomously divided into numerous capillary segments, interspersed with little globular traps or bladders. Traps obliquely ovoid, 1–4 mm, stalked. Scapes usually 7–15 cm, bearing a raceme of 3–6(–10) flowers; scales absent; bracts basifixed. Pedicels erect and slender at flowering time, turned downward at fruiting time. Calyx deeply bilobed; lobes ovate, unequal, enlarged and spreading in fruit. Corolla yellow, 10–15 mm, upper lip broadly ovate, apex rounded, about twice the length of upper calyx-lobe, lower lip larger, transversely elliptic; the spur obtuse, about the length of lower corolla-lip. Ovary ovoid; style distinct. Capsule globose, 4–5 mm in diam., circumscissile; persistent style about twice as long as the capsule.
