Impatiens macrovexilla Y. L. Chen var. yaoshanensis S. X. Yu, Y. L. Chen & H. N. Qin, a new variety of Balsaminaceae from Guangxi, China, is described. Variety yaoshanensis differs from the typical variety by having ovate-orbicular or ovate-oblong leaves, entire lateral sepals, an obvious auricle and entire distal lobe of the alae and visibly ridged seeds. Micromorphological characters of the pollen grains and seed surface under SEM of the two varieties also support the recognition of this taxon. 相似文献

描述了中国云南姜科Zingiberaceae一新种——苍山象才参Roscoea cangshanensisM.H.LUO,X.F.Gao&H.H.Lin。该种与大理象牙参R.forrestii Cowley在体态上相近,但唇瓣深裂成2裂片,每个裂片再2裂,基部收缩成具白色条纹的柄,叶片较狭窄,(2-)7-24×1.5-2.5cm,叶片基部狭缩成叶柄状而不同。该新种叶片基部狭缩成叶柄状,唇瓣倒卵状楔形,长2.5-3.5cm,宽2.5-3.0cm,基部收缩成具白色条纹的柄,与长柄象牙参R.debilis Gagnep.相似,但苞片非管状,较短,长5-15mm,隐藏于叶鞘内,花冠管较长,10-12.5cm,唇瓣深裂成2裂片,每个裂片再2裂,可与后者明显区别。 相似文献
