摘要

Tecticornia bibenda K.A. Sheph. & S.J. van Leeuwen, a new species of conservation significance is described and illustrated. Previously Tecticornia indica (Willd.) K.A. Sheph. & Paul G. Wilson (formerly Halosarcia indica (Willd.) Paul G. Wilson) was the only member of the Salicornioideae that was known to have a modified Kranz anatomy indicative of the C< sub>4 photosynthetic pathway. Anatomical evidence indicates that T. bibenda shares a similar modified anatomy. While T. bibenda is related to T. indica, it is distinguished by the presence of unusually large vegetative and fertile articles and having paired cymes of (4)5-7 flowers rather than the more typical 3-flowered cymes. This species is restricted to the flood zones and fringing spinifex/samphire heath of several gypsiferous playa and salt lake systems in the Little Sandy Desert of Western Australia. Due to its restricted distribution this species has a Priority three conservation status.

Wilson）是S线虫科中唯一已知具有修饰的Kranz解剖结构的物种，该结构指示C 4 光合途径。解剖学证据表明，本本氏螺旋体具有相似的改良解剖结构。尽管比本斯猪笼草（T. bibenda）与印度。草（T. indica）有关，但它的特点是存在异常大的营养和肥沃物品，并且具有成对的（4）5-7花聚伞花序，而不是更典型的三花聚伞花序。该物种仅限于西澳大利亚州Little Sandy Desert的几个吉普赛滩和盐湖系统的洪泛区和边缘棘缘/桑弗莱荒地。由于其分布受限，该物种具有三级优先保护地位。
