云南樟科油丹属一新种——黄连山油丹

报道了樟科油丹属一新种，即黄连山油丹Alseodaphne huanglianshanensis H. W. Li & Y. M. Shui。它产自中国云南东南部绿春县黄连山海拔840-1300 m的热带阔叶次生林中，在体态上与同一分布区内的云南油丹A. yunnanensis Kosterm.十分相似，但叶为长圆形或倒披针状长圆形(5-13×(0.8-)1.2-2.8 cm)，明显较狭，两面几无蜂窝穴，总梗及果梗无毛，密被灰白色小瘤而不同。该新种也与油丹A. hainanensis Merr. 相似，但叶长圆形至倒披针状长圆形，坚纸质，先端锐尖或渐尖，两面几无蜂窝穴，侧脉每侧7-8条，果梗长5-7 mm，密被灰白色条形的小瘤而不同。     

徐氏蕨属——中国云南早泥盆世陆地植物的一个新属

  A new psilophytic plant, Hsüa robusta, is found in the Xujiachong Formation  (Emsian) of the Lower Devonian from the Qüjing (= Kütsing) district of Yunnan,  China.  This plant is tentatively referred to the Cooksoniaceae of Rhyniales.       Hsüa gen. nov.       Type species: Hsüa robusta (Li et Cai) C. S. Li.       Diagnosis:  Plants erect and then creeping. Main axes dividing pseudomonopodial- ly and bearing dichotomous lateral branches which somewhat differentiate into vegeta, tire and fertile ones, with dichotomous root-like and rhizophore-like appendages.  Spo- rangia terminal, round to reniform or wide reniform, dehiscing along distal margin into two equal halves.  Spores homosporous, trilete.  Stomata anomocytic.  Protostele cen- trarch.       Hsüia robusta (Li et Cai) C. S. Li, comb. nov.       Cooksonia zhanyiensis Li et Cai, Acta Geologica Sinica, 52 (1) 1978, p. 10, pl. II, fig. 6.——Taeniocrada robusta Li et Cai,ib. p. 10, pl. II, fig. 7—14.       Diagnosis:  Characters same as in generic diagnosis. Main axes 6—10 mm wide and at least 24 cm long, with vascular strands 1.2—2.4 mm acr  oss.  Fertile branches 3—4 times equally or unequally dichotomous, 10—1.5 mm in width and up to 11 cm in length, possessing a vascular bundle of 0.5 mm in its greatest diameter.  Branches circinately coiled in apical regions.  Axial tubercles, root-like and rhizophore— like appendages aris- ing from the main axes usually anterior to the lateral branches. Axial tubercle round with a diameter of 2.2—2.4 mm, having a vascular bundle about l mm across.  Root- like branches 3 times bifurcate, 1—0.3 mm wide and up to 1.5 cm long, with a vascular bundle about 0.1 mm across.  Rhizophore-like appendages forked, 3—1.7 mm in width, possessing a vascular bundle of 0.7 mm in its greatest diameter. Root-like protuberances sometimes arising from rhilzophore-like branches.   Epidermal cells of axes generally elongate, measuring 60—290μby 25—60 μ.  Stomata mainly fusiform, 90—110 μ long and 50—60μ wide, consisting of a pair of guard cells enclosing a pore 6—15μ  in length and 1—3μ  in width.  Cuticle of guard cells quite thick.  Stomatal density about 5 per mm2.  Sporangia 0.8—4.2 mm high, 1.0—8.2 mm across, usually having a dehiscent distal border which measures 50—100μ broad.  Demarcation between sporangium and its stalk quite clear.  Epidermal cells of basal part of sporangial walls elongate, about 100 μ long and 30μ wide, but those of distal part isodiametrally polygonal, about 50μ in diame- ter.  Stomata, radially arranged scattering over sporangial walls, generally round about 50μ in diameter and 50 per sporangium.  Spores round, 18—36μ (average 27μ) indiameter, and smooth.  Tracheids of protoxylem about 10μ across; those of metaxylem about 30μ across, with scalariform thickening.      This plant is similar to Renalia hueberi Gensel in general morphology, but differs from the latter in possessing root-like and rhizophore-like branches.      The generic name is derived from Prof.  Hsü Jen.     This paper is a thesis for M. Sc.
