摘要：
在广东省德庆县进行全国第四次中药资源普查时采集了大量标本，经过鉴定和查阅相关资料，确定其中一号标本为紫花苣苔属(Loxostigma Clarke) 东兴紫花苣苔［Loxostigma dongxingensis (Chun ex K. Y. Pan) Möller & Y. M. Shui］。该属及该种在广东尚无分布报道，这是首次发现。紫花苣苔属为草本或亚灌木，根状茎匍匐或不存在，花冠粗筒状，檐部二唇形，雄蕊4，花药顶端成对连着，两对雄蕊紧密靠合，种子两端具毛状附属物。紫花苣苔属目前共11种，我国、尼泊尔、锡金、不丹、印度、缅甸及越南北部均有分布，在我国11种全产，分布于四川、云南、贵州和广西，广东首次记录。目前广东省是紫花苣苔属自然分布的最东界。东兴紫花苣苔为多年生草本，具横走根状茎，茎高为20～60cm，花冠粗筒状，黄色，下方肿胀，近基部之上、中部之下突然收缩呈缢缩状，檐部2唇形，雄蕊 4，花药成对连着，分布于广西及越南北部，广东首次记录，发现地位于德庆县象牙山林场，种群沿山间溪流两侧分布，生于林下沟谷旁光线较暗处。
A large number of specimens were collected during the pilot work of the Fourth National Survey on Traditional Chinese Medicine Resources in Deqing County, Guangdong Province. One of them was identified as Loxostigma dongxingensis (Chun ex K. Y. Pan) Möller & Y. M. Shui, belongs to Loxostigma Clarke, which was never recorded before in Guangdong. Loxostigma species are perennial herbs or subshrub， having rhizomes or not. Corolla bilabiate, tube broadly tubular, stamens 4, anthers coherent in pairs at apex, and two pairs of stamens are gradually connivent. Seeds with one hairlike appendage at each end. Loxostigma species are similar to Briggsia species. There are eleven spsecies in Loxostigma so far, distributed in Bhutan, China, India, Myanmar, Nepal, Sikkim, and North Vietnam. All eleven species distribute in China (Sichuan, Yunnan, Guizhou and Guangxi) . This is the first record in Guangdong. Guangdong is the most east boundary where Loxostigma naturally distributed. L. dongxingensis is perennial herbs, stems 20－60 cm, corolla yellow, swelling at the base, then become constricted above the base and below the middle, stamens 4, anthers coherent in pairs, distributed in Guangxi and North Vietnam, first recorded in Guangdong, grows in shaded dense forest near streams in Xiangyashan Forest Station of Deqing County.

摘要：
描述了发现于中国西南部广西壮族自治区苦苣苔科植物一新种，白萼报春苣苔。新种因为它具有黄色的花朵、白色花萼裂片和大苞片与癞叶报春苣苔相似，但很容易通过叶片、花梗和花冠的一些定性和定量的性状与后者进行区分。根据IUCN名录的分类和标准，白萼报春苣苔的保护现状可被视为“极度濒危”（CR）。
Primulina albicalyx, a new species of Gesneriaceae from Guangxi Zhuang Autonomous Region, SW China, is described and illustrated. This new species is similar to P. leprosa by its yellow flowers, white calyx lobes and large bracts, but can be easily distinguished from the latter by some qualitative and quantitative characters in the leaf blade, peduncle and corolla. The conservation status of P. albicalyx can be considered as Critically Endangered (CR) according to the IUCN Red List categories and criteria.
