細苞蟲實（學名：Corispermum stenolepis）為莧科蟲實屬的植物，是中國的特有植物。分布於中國大陸的遼寧等地，生長於海拔350米至700米的地區，多生於河灘以及固定沙丘上，目前尚未由人工引種栽培。 [1]
細苞蟲實形態特徵
莖直立，高15-50厘米，圓柱狀，直徑1.5-2毫米；分枝纖細，多集中於中上部，長7-35厘米，通常下部分枝較長。
葉條形，極狹，長約3.5厘米，有時達4.5厘米，寬約1毫米，先端漸尖具小尖頭，基部漸狹，全緣，1脈。穗狀花序頂生或側生，纖細，具稀疏的花；苞片由條狀披針形至披針形，先端漸尖具小尖頭，長0.6-3.5厘米寬1-2毫米，顯著地比果狹。
花被片1，寬橢圓形，長0.9-1.2毫米，寬約0.6毫米；雄蕊1-3，花絲比花被片長。
果實近圓形，長4.5-5.5毫米，寬3.9-5毫米，頂端下陷呈深的缺刻，基部心臟形，背面凸起中央扁平，腹面凹入，兩面均被星狀毛；果核長橢圓形，長約3毫米，寬約1.5毫米；果喙長1.5-1.7毫米，喙尖為喙長的1/4,外彎；果翅寬，與果核寬相等或較核稍寬，薄，半透明，向兩側彎曲，緣具不規則細齒。花果期8-9月。

Corispermum stenolepis var. psilocarpum Kitagawa.
Plants 15-40 cm tall. Stem erect, terete, branched mostly from upper-middle part; branches slender, 10-35 cm. Leaves linear, 3.5-4.5 cm × ca. 1 mm, 1-veined, base attenuate, margin entire, apex acuminate, mucronate. Spikelike inflorescence slender, loose; bracts linear-lanceolate to lanceolate, 0.6-3.5 cm × 1-2 mm, narrower than utricle, apex acuminate, mucronate. Perianth segment 1, broadly elliptic, 0.9-1.2 × ca. 0.6 mm. Stamens 1-3; filaments longer than perianth segments. Utricle suborbicular, 4.5-5.5 × 4-5 mm, glabrous, subglabrous, or covered with stellate hairs, base cordate, apex deeply emarginate; wing equaling or slightly wider than body, margin irregularly denticulate; beak 1.5-1.7 mm, apex ca. 1/4 as long as beak, recurved. Fl. and fr. Aug-Sep.

Plants with glabrous utricles were described as Corispermum stenolepis var. psilocarpum and reported from W Jilin. However, the typical variety also seems to have utricles glabrous or nearly so (there is no indication of utricle pubescence in the protologue of the species), and thus these infraspecific entities probably do not merit any formal taxonomic recognition.
Corispermum stenolepis and C. platypterum are related to C. macrocarpum and the North American C. pallidum Mosyakin (C. subsect. Platyptera Mosyakin).
