Corydalis pseudoweigoldii Z. Y. Su in Addenda.
灰绿色草本,高30-50厘米。根茎小,约长8毫米,粗5毫米,具小而肥厚的鳞片状叶基和簇生须根,具1茎。茎基部常多少弯曲,具柔毛,下部的叶不发育,常退化成鳞片状,约中部以上具叶和分枝,鳞片和下部叶腋常具珠芽,有时下部鳞片腋内具须根。基生叶非常退化,常早枯。茎生叶具长柄至具短柄,叶片近三角形,上面绿色,下面苍白色,二回三出,一回羽片具柄,二回羽片无柄,顶生的约长2厘米,宽1.5厘米,侧生的约长1.5厘米,宽1.2厘米,基部楔形,上部三深裂,裂片三浅裂,末回裂片圆钝,具急尖。总状花序疏具6-10花。最下部的苞片叶状,具柄,其余的扇形深裂,三裂至披针形,约与花梗等长或稍短。下部花梗长约1.5-1.8厘米,上部的长约7毫米。花蓝色,平展,有时距多少上弯。萼片大,圆形,直径2-2.5毫米,具浅齿。外花瓣渐尖,无鸡冠状突起,瓣片不甚宽展,具耳状突起。上花瓣长2-2.5厘米;距圆筒形,近直,约与瓣片等长,向后稍变狭;蜜腺体约占距长的2/3。下花瓣长约1.5厘米,向后渐变狭。内花瓣长约1.3厘米。子房线形,具细长的花柱;柱头扁四方形,前端具2短柱状突起,基部稍下延,侧面具3对无柄的双生乳突。蒴果线形,自果梗顶端多少折曲,长约1.4厘米,具1列种子和长约5毫米的花柱。
产四川西南部(盐源),生于海拔3600-3800米左右的山坡冷杉林下,模式标本采自盐源。
本种的花色和花的大小,以及外花瓣具耳状突起而无鸡冠等特征都非常相似川西紫堇C. weigoldii Fedde, 但它们的叶、苞片、子房(具1列还是二列胚珠)柱头和花序均十分不同。

假川西紫堇 jia chuan xi zi jin
Herbs, perennial, 30-80 cm tall, lower part of stem usually pubescent. Rhizome short, knotty, 10-20 × 5-10 mm, crowned by sparse leaf rosette with bulblike base (sometimes absent?). Stems 1 or few, suberect to ascending (and then sometimes rooting at lower nodes), slender, usually much branched, with 5-8 scattered leaves. Rosette leaves few at anthesis; petiole 6-15(-20) cm; blade glaucous abaxially, green adaxially, triangular, 4-6 × 4-7 cm, biternate; primary leaflets stalked; secondary subsessile, cut 1/2-2/3 into obovate lobes again shallowly divided to crenate-dentate at apex; teeth obtuse, mucronulate. Cauline leaves like radical leaves (lower ones early withering); petiole 1-10 cm, lower long, upper short; blades progressively smaller upward, uppermost often only 1-2 cm. Racemes 7-15(-20)-flowered, terminal and axillary from upper leaves, rather dense at anthesis, elongating to 7-15 cm in fruit; lower bracts to 2 cm, stalked, cut into 3-5 deeply and acutely dentate lobes; middle and upper bracts progressively smaller, entire to large dentate. Pedicel thin, 6-15 mm in flower, 10-20 mm in fruit. Sepals broadly ovate, 1.5-2.5 × 1-2 mm, finely dentate. Flowers purplish blue to reddish purple. Outer petals ecristate, subacute to shortly acuminate; upper petal 19-25 mm; spur straight to upturned at base, straight to slightly downcurved at apex, slightly attenuate to obtuse apex, 10-13 mm; nectary 2/3-3/4 as long as spur; lower petal 12-15 mm, claw narrow, widened into a rhombic-acute limb; inner petals 11-13 mm. Stigma quadrangular; marginal apical papillae: 2 median distinct, lateral diffuse; geminate papillae lateral (submarginal) and on well-developed basal lobes. Capsule pendent from straight erect-spreading pedicel, linear, 14-20 mm, 7-11-seeded; style ca. 3 mm. Seeds in 1 row. Fl. Jul-Aug.
