1997 ~ 1999年中国南方有德保苏铁（Cycas debaoensis） Zhong yc.c. & Chen c.j and changjiangensis N. Liu。四川苏铁的野生居群是在福建发现的。高海拔的贵州苏铁（K. M. Lan & R. F. Zou）和低海拔的南攀江沿岸苏铁（C. segmentfiida D. Y Wang & C. Y Deng）被Chen and Wang（1995）和Chen and Stevenson（1999）视为四川苏铁的同属种。然而，Chen和Stevenson（1999）和本作者已经减少了另外11个新种。它们是C. longlinensis Huang t Chang & yc . Zhong， C. xilinensis Huang t Chang & yc . Zhong， C. multifida Huang t Chang & yc . Zhong， C. longiconifera Huang t Chang & yc . Zhong， C. acuminatissima Huang t Chang & yc . Zhong，均被视为C. segmentifida的同义词。苏铁（Cycas spiniformis Liang j.y., c.l ongisporophylla f.n.a）， c.p septermsperma Huang tchang &张洪祥，c.p brevipinnata Huang tchang等应与c.c exsemifera f.n.a同义。苏铁和伊壁加斯·米奎里（瓦布）·德·劳布。应该是C revoluta的同义词，因为它们的“类型”标本有点像C revoluta。红河自然苏铁保护区是近年来在云南建立的，主要保护多羽苏铁和红河苏铁。德宝苏铁保护区即将建立。然而，由于资金短缺和管理不善，中国现有的大多数苏铁保护区都没有这么成功。建立了广西南宁青秀山苏铁园迁地保护。苏铁苗圃已经开始出现在中国南方的一些村庄。
From 1997 to 1999 Cycas debaoensis Y. C. Zhong & C. J. Chen and C. changjiangensis N. Liu were described from South China. The wild populations of Cycas szechuanensis were discovered in Fujian. Cycas guizhouensis K. M. Lan & R. F. Zou at the higher elevations and C. segmentifida D. Y Wang & C. Y Deng at the lower elevations along the Nanpanjiang River should be good species, which were treated by Chen and Wang (1995) and Chen and Stevenson (1999) as synonyms for C. szechuanensis. However, 11 other new species have been reduced by Chen and Stevenson (1999) and the present authors. They are C longlinensis Huang T. Chang & Y. C. Zhong, C. xilinensis Huang T. Chang & Y. C. Zhong, C. multifida Huang T. Chang & Y. C. Zhong, C. longiconifera Huang T. Chang & Y. C. Zhong, and C. acuminatissima Huang T. Chang & Y. C. Zhong, all treated as synonyms of C. segmentifida. Cycas spiniformis J. Y. Liang, C. longisporophylla F. N. Wei, C. septermsperma Huang T. Chang & H. X. Zhang, C. brevipinnata Huang T. Chang et al. should be synonyms for C. exseminifera F. N. Wei. Cycas miquelii Warb. and Epicycas miquelli (Warb.) de Laub. should be the synonyms for C revoluta because their "type" specimens are somewhat like C. revoluta. The Honghe Nature Cycad Reserve for Cycas multipinnata and C. hongheensis was recently established in Yunnan. The Debao Cycad Reserve will be established soon. However, most existing cycad reserves in China have not been so successful because of shortages of funding and poor management. In ex situ conservation the Qingxiushan Cycad Garden in Nanning, Guangxi, was established. Cycad nurseries have begun to appear in some villages in South China.
