Gouvêa & Giacomin, , is described from central Brazilian Atlantic Forest. It is known from only three localities in Espírito Santo and Minas Gerais states, where granitic/gneissic outcrops (inselbergs or sugar loaves) are ubiquitous. The new species, here described, belongs to Solanum subgenus Leptostemonum (or the Leptostemonum clade; i.e. the spiny solanums) and is morphologically related to Vell. and Hiern, with which it shares the shrubby habit, decurrent leaf bases and well-developed calyces that become accrescent, covering glabrous fruits. is unique in its combination of comparatively more delicate habit, indumentum of exclusively stellate eglandular trichomes, accrescent but never inflated fruiting calyces that only partially cover the fruits and comparatively shortly lobed and strictly white corollas. The species is threatened with extinction and assessed as Vulnerable (VU), based on the IUCN criteria.
古韦亚和贾科明……是从巴西大西洋森林中部描述的。仅在圣埃斯皮里图州和米纳斯吉拉斯州的三个地方发现过它，那里花岗岩/片麻岩露头（孤山或糖面包山）随处可见。这里描述的新物种属于茄属亚属Leptostemonum（或Leptostemonum分支；即多刺茄属），在形态上与韦尔……和希尔恩有关，与它们一样具有灌木习性、下延的叶基部以及发育良好且会增大的花萼，花萼覆盖着无毛的果实。……的独特之处在于其相对更纤细的习性、仅具星状无腺毛的毛被、增大但从不膨大且仅部分覆盖果实的结果时的花萼以及相对较短的裂片和严格为白色的花冠。根据国际自然保护联盟的标准，该物种面临灭绝威胁，被评估为易危（VU）。
