Delphinium orthocentrum Franch. in Bull. Soc Philom. Paris, ser. 8, 5: 178. 1893; Huth in Bot. Jahrb. 20: 458. 1895; 王文采, 植物学报 10: 143. 1962; Munz in Journ. Arn. Arb. 49: 109, f. 15, c. 1968. ——D. szechuanicum Ulbr. in Rep. Sp. Nov. 14: 298. 1916.
茎高50-100厘米，下部无毛，上部与叶柄和花序被贴伏的短柔毛，等距地生叶。茎中部叶有稍长柄；叶片五角形，长3.6-4.2厘米，宽6.2-7厘米，三深裂至距基部3毫米处，深裂片互相稍分开，中央深裂片菱形，渐尖，下部全缘，近中部三裂，二回裂片有卵形牙齿，侧深裂片斜扇形，不等二深裂，两面有短曲柔毛；叶柄比叶片稍长。茎上部叶渐变小。总状花序长约12厘米，约有10花；基部苞片叶状，其他苞片小，钻形，长7毫米以下；花梗长1-3厘米；小苞片与花邻接或距花1-2毫米，钻形，长3.5-5毫米，有短毛；花长1.5-2厘米；萼片蓝紫色，倒卵形，长10-13毫米，外面密被短柔毛，距与萼片近等长，圆锥状圆筒形，下部向上弯曲；花瓣蓝色，无毛，顶端二浅裂；退化雄蕊与萼片同色，瓣片二裂至中部，腹面有黄色髯毛；雄蕊无毛；心皮3，子房疏被短柔毛。8月开花。
产四川西北部松潘一带。
本种的主要特征是花较小，萼距向上弯曲，根据这特征易与近缘种区别。
