備註: reviewed by crawford law on 5-4-2023 鄧敏, 李謙盛, 曹明, 席世麗.雷公青岡和滇南青岡學名訂正[J].廣西植物,2011,(2):148-152. 雷公青岡 Q. hui 為Chun(1928)根據陳煥鏞 (W. Y. Chun)5868號標本發表的新種。在原始文獻中,陳煥鏞描述:“該種與Q:championii (嶺南青岡接近,區別在於葉片較薄,星狀毛被僅殘存於葉中脈近基部,較大果實”。筆者在對青岡亞屬進行全面修訂時發現,該種葉型和果實形態和分佈於越南北部的Q. auricoma A. Camus 在形態上完全一致 ,實為同種植物,故作為異名進行歸併。 internal ref loc 雷公新葉係銹色綿毛; 老葉沒毛.雌雄同株(thanks crawford's info) 深圳植物誌: 喬木。植株高10—15m。嫩枝密被黃色捲曲的絨毛,後漸無毛,有細小皮孔。葉柄長1—1.4cm,幼時被綿狀毛;葉片薄革質,長橢圓形、倒披針形或橢圓狀披針形,長7—13cm,寬1.5—3(4)cm,基部楔形,略偏斜,邊緣全緣或頂端有數對不明顯的淺鋸齒,葉緣反捲,先端圓鈍,稀漸尖,下面初被黃色絨毛,後毛漸脫落,中脈下面凸起,上面平坦,側脈每邊6—10條,網脈下面明顯。 雄花序2—4個簇生,長5—9cm,被黃棕色絨毛;雌花序長1—2cm,有花2—5朵,聚生於花序軸頂端。果序長1cm,有果1—2個;殼鬥淺碗形或深盤形,高0.4—1cm,直徑1.5—3cm,包裹堅果基部,殼壁厚約1mm,內外壁均密被黃褐色絨毛;同心環4—6圈,邊緣呈小齒狀;堅果扁球形,高1.5—2cm,直徑1.5—2.5cm,嫩時密生黃褐色絨毛,後毛漸脫落,果臍凹陷,直徑0.7—1cm,柱座凸起。花期:4—5月;果期:10—12月。 有關Quercus auricoma 跟Quercus cambodiensis 曾被處理為同物異名: Quercus cambodiensis Hickel & A.Camus Quercus cambodiensis Hickel & A.Camus, Bull. Mus. Natl. Hist. Nat. 29: 600 (1923); [P. H. Lecomte et al.] Fl. Indo-Chine 5: 946 (1929). Quercus auricoma auct. non A.Camus; Tagane et al., Tree Fl. Bokor National Park: 277 (2017). While Q. cambodiensis is treated as a synonym of Q. auricoma by Tagane et al. (2017), those two species are not sister to each other in both Bayesian and MIG-seq trees. The treatment of Tagane et al. (2017) is based on the broad concept of Q. auricoma adopted in the Flora of Thailand (Phengklai 2008) in which a species morphologically similar to Q. cambodiensis in northern and north-eastern Thailand is treated as Q. auricoma. However, after examining the collection of Q. auricoma from Son Tra (V3135, V3138) that is morphologically identical with the species of the type specimen of Q. auricoma, it is concluded that the species treated as Q. auricoma in the Flora of Thailand (Phengklai 2008) is different from genuine Q. auricoma, in that leaves are serrate along the upper 1/2–1/3 margin (vs. completely entire in Q. auricoma), nuts ovoid to oblong (vs. suborbicular) and cupules densely hairy (vs. less hairy). As far as is known, Q. auricoma is endemic to Vietnam. Further studies are needed to elucidate the identity of the species called “Q. auricoma” in Thailand. Bingh, H.T. & al. (2018).
