摘要
描述了龙血树属Dracaena一新种——深脉龙血树D.impressiveniaY.H.Yan&H.J.Guo,并绘了线图。该种产于中国云南盈江县,与矮龙血树D.ternifloraRoxb.叶形相似,但侧脉深陷,总状花序上具许多每6–9朵簇生的花,苞片暗红色,花被伸直,长3–3.5cm,可与后者明显区别。
Dracaena impressivenia Y. H. Yan ＆ H. J. Guo, a new species from Yingjiang County, Yunnan, China, is described and illustrated. This species is similar to D. terniflora Roxb. in the leaf shape, but differs by having sunken-veined leaves, many-flowered raceme with 6-9 flowers clustered together, dark red bracts, and erect perianth 3-3.5 cm long.
