One new species and one new variety of Gesneriaceae in Vietnam are described, viz. Paraboea sinensis var. glabrissima and These two new taxa grow in limestone regions in North Vietnam. The former new variety differs from Paraboea sinensis (Oliv.) Burtt var. sinensis in its young leaf abaxially, stem and peduncle sparsely and thin pannose, acute top of leaves, pistil glandular-pubescent or pubescent. The latter new species differs in its bracts 1.6-2.5 × 1.3-1.5 cm, corolla 3-3.5 cm long, corolla tube slightly curved near the base and inflated on the adaxial surface near the corolla lobes, and corolla abaxial lip lobes rounded. The two new taxa grow at Xuan Son National Natural Reserve, North Vietnam and remain undisturbed with low risk of extinction.
描述了越南苦苣苔科的一个新物种和一个新变种，即中华蛛毛苣苔光滑变种（Paraboea sinensis var. glabrissima）和[此处原文缺失物种名]。这两个新分类群生长在越南北部的石灰岩地区。前一个新变种与中华蛛毛苣苔（Paraboea sinensis (Oliv.) Burtt var. sinensis）的区别在于其幼叶背面、茎和花梗稀疏且薄被柔毛，叶尖尖锐，雌蕊具腺毛或被柔毛。后一个新物种的区别在于其苞片1.6 - 2.5×1.3 - 1.5厘米，花冠长3 - 3.5厘米，花冠管在基部附近稍弯曲，在靠近花冠裂片的正面膨胀，花冠背面唇裂片圆形。这两个新分类群生长在越南北部的宣光国家自然保护区，未受干扰，灭绝风险较低。
