It is distinguished from the allied P. kurrooa Royle ex Benth. by being 10–25 cm tall, having a moderately dense, (10–)15–25‐flowered spike, a zygomorphic, 2‐lipped, glandular‐ciliate corolla that is equaling or slightly exceeding the calyx and partly visible or sub‐exserted between the calyx lobes, a conspicuously long (longer than the corolla lobes), curved corolla tube (1/2–4/5 the length of the calyx), unequal corolla lobes that are ovate‐lanceolate to lanceolate, acute to sub‐acuminate and moderately ciliate, a mid‐lobe of the upper lip that is obliquely erect, galeate with retuse or emarginate apex, lateral corolla lobes that are slightly smaller than the mid‐lobe of the upper lip, a lower corolla lip that is slightly shorter than the lateral lobes, obliquely erect or spreading, didynamous, long‐exserted (2–3 times the corolla) stamens, pollen of the Paederota‐type and a style that is 2–3 times as long as the corolla.     

Two new species of <Emphasis Type="Italic">Gentianella</Emphasis> (Gentianaceae) from Peru

Two new species of Gentianella (Gentianaceae, Gentianeae, Swertiinae), G. grantii and G. wayqecha, are described from Departamento Cusco, Peru. These two species differ from other Peruvian species of Gentianella in a combination of stems 10–100 cm long; no rosette of basal leaves; cauline leaves 10–75 mm long; flowers in thyrses; and corollas 14–26 mm long, campanulate, and adaxially glabrous. The leaves of G. grantii consist of an appressed pseudopetiole and a spreading, narrowly elliptic-oblong to linear blade; the corollas are lavender; and the corolla lobes are 0.6–0.7× as long as the tube. Gentianella grantii is similar to G. lythroides, of Bolivia, but differs in having more closely spaced leaves and less deeply lobed corollas. The leaves of G. wayqecha are sessile, lanceolate to ovate; the corollas are rose-violet; and the corolla lobes are 0.75–1.35× as long as the tube. Gentianella wayqecha is similar to G. rapunculoides, of Colombia and Ecuador, and G. ruizii, of Peru, but differs from both in its adaxially glabrous corollas and from G. rapunculoides in its less deeply lobed corollas. Both G. grantii and G. wayqecha grow in moist habitats near tree line, and are known only from a area northeast of the city of Cusco.     

Primulina xiziae sp. nov. (Gesneriaceae) from Zhejiang Province,China

A new species of Gesneriaceae, Primulina xiziae Fang Wen, Yue Wang & G. J. Hua, from Zhejiang Province, China, is identified, illustrated and described. It resembles the widespread P. eburnea, and the stenochoric P. pseudoeburnea, but differs by the leaf blades being ovate‐elliptic or ovate, chartaceous with ciliate margins, 8.5–13.8 mm long, slender peduncle, ovate, ca 1.2 × 1.0 cm large bracts that are generally withered but persistent before full‐blooming stage, slender tubular‐infundibuliform, ca 25.0 × 7.5 mm corolla tube, limb lobes with acute apices, 3 staminodes, and by forming a dormancy bud in winter.     

Aristolochia bidoupensis sp. nov. from southern Vietnam

Aristolochia bidoupensis Do sp. nov. is newly described. This new species, currently only known from southern Vietnam, is most similar to Aristolochia faviogonzalezii (northern Vietnam) and A. moupinensis (China), but can be distinguished from the latter two by the following characters: flowers terminal, axillary, solitary, peduncle 1.3–1.5 cm long, bracteole ovate, 3–4 × 2–3 mm, limb discoid‐shaped with three expanded lobes, not revolute, internal surface uniformly dark purple, smooth, throat uniformly golden without dots. Morphological characters such as a 3‐lobed gynostemium and a 3‐lobed limb place the new species in A. subgen. Siphisia.

Length–weight relationships of two Nemacheilid fish species [Schistura fasciata Lokeshwor and Vishwanath, 2011 and Schistura reticulofasciata (Singh and Bănărescu, 1982)] from Simsang River,Meghalaya, India

Length–weight relationships (LWRs) are presented for two fish species: Schistura fasciata Lokeshwor and Vishwanath, 2011 and Schistura reticulofasciata (Singh and B?n?rescu, 1982), sampled from the Simsang River in Meghalaya, India. Fishes were caught seasonally from January to December 2015, with cast nets (10–15 mm mesh size) and electrofishing devices. The b values in the LWRs were determined as 3.09 for S. fasciata and 3.318 for S. reticulofasciata.

PICEA WOLFEI,A NEW SPECIES OF PETRIFIED CONE FROM THE MIOCENE OF NORTHWESTERN NEVADA

Several silicified ovulate cones from the late middle Miocene (Barstovian) represent a new species, Picea wolfei Crabtree. This is the second species of Picea for which structurally preserved seed cones are known to be reported from the Tertiary. The cones are 5.0–8.0 cm long and 1.5–2.0 cm at their greatest diameter. Ovuliferous scales are inserted helically around the cone axis and are recurved at their point of divergence. Each scale is broadly obovate to spatulate with a rounded apex and bore two seeds adaxially. The bract subtending the scale is 4.5–7.3 mm long and is fused to the scale for 1.4–2.0 mm. Each bract has an inflated keel-like base which projects abaxially between the seeds of adjacent scales. The fossil cones superficially resemble those of the extant Picea breweriana, yet differ from them anatomically. The new species also resembles Picea lahontense, a fossil compression from the Miocene Trout Creek Flora of south-central Oregon, but the different modes of preservation preclude meaningful comparison. Picea diettertiana, the only structurally preserved fossil cone of this genus previously described, is quite dissimilar in that it lacks a sclerotic pith.
