A new species of Polygonatum (Asparagaceae), Polygonatum caulialatum S. R. Yi from Bashan canyon of Xuanhan, Dazhou, Sichuan, China, is described in this paper, it is similar to P. cyrtonema Hua and P. odoratum (Miller) Druce in appearance for stem glabrous, leaves alternate, corolla campanulate, stamens not exposed, ovary glabrous and berries black, but differs from the former in middle and upper stem slightly flat with two distinct narrow wings, inflorescences 1–2(–3)-flowered, longer perianth lobes, filaments cylindrical and apically not inflated, longer styles and more seeds per berry; and differs from the latter in thicker moniliform rhizome, middle and upper stem slightly flat with two distinct narrow wings, longer perianth lobes, filaments cylindrical, longer anthers and styles, more seeds per berry.

A New Species

No species of Colletotrichum have been reported associated with Vaccinium dunalianum var. urophyllum, which is a significant medicinal plant in China. In this study, several endophytic strains were isolated from this host. Morphology and analysis of DNA sequences of nuc rDNA ITS1-5.8S-ITS2 (ITS barcode) and seven other gene regions (GAPDH, CAL, ACT, CHS-1, HIS, GS, TUB2) revealed a new species, Colletotrichum yulongense and a previously described species, C. rhombiforme. Both Colletotrichum species are described. The diversity and broad distribution of the host, suggest the likelihood of other endophytic Colletotrichum species in V. dunalianum var. urophyllum and this requires further investigation. The pathogenicity of the Colletotrichum species isolated from V. dunalianum var. urophyllum also needs testing.

A New Species

Paris polyphylla is an important perennial medicinal plant in China. A disease similar to gray mold on P. polyphylla occurred at the seedling stage in March 2016 and 2017 in Tengchong city, Yunnan Province of China. The disease resulted in up to 50% mortality in serious cases. Isolates from diseased plants grew 10.6 mm/day at 20°C on PDA. After 21 days, sclerotia were spherical to elliptical (0.4–2.5 × 0.3–1.8 mm). Conidia from diseased tissues were hyaline to pale brown, long, ovoid, unicellular, and measured 15.1–24.5 × 8.8–13.4 μm; conidiophores were 526–1,064 ×12–15 μm. Isolates did not form conidiophores or conidia on PDA or MYA. A phylogenetic analysis based on G3PDH, RPB2, and HSP60 sequence data supported assignment of three representative isolates as a new species of Botrytis. Based on morphological, phylogenetic characteristics and Koch’s Postulates, the causal agent of gray mold on P. polyphylla was identified as a novel species, Botrytis polyphyllae.

A New Species

Piper Linnaeus (1753:28) is a Pantropical genus that comprises about 2000 species (Quijano-Abril et al. 2006). This genus is economically important because is widely used as spice, as P. nigrum Linnaeus (1753:28) (black pepper) and as a medicinal plant across the world. Babu et al. (1993) described a new species and a variety to the genus from Southern India: Piper sugandhi Ravindran, Babu & Naik (1993:27) and P. sugandhi var. brevipilis Ravindran, Babu & Naik (1993:27). The authors provided diagnosis for the new species and variety, and compared it with the related taxa. However, they have indicated two gatherings as holotypes (a male and a female specimen) and according to Arts. 8.1 and 40.1 of the ICN these two names are not validly published (McNeill et al. 2012).

Important Medicinal Plant

A new species of the genus Psalmocharias Kirkaldy, 1908, P. akesensis sp. nov., from Xinjiang, China is described. A key to all species of Psalmocharias is provided. This new species feeds on the medicinal plant Ephedra intermedia Schrenk ex Mey, which contains various medicinally active alkaloids (notably ephedrine) and stimulates the central nervous system and influence muscle contraction of animals. The discovery of this new species may be informative for future studies of the detoxification mechanism in insects and for the protection of this important medicinal plant.

A New Species

Cyrtomon luridus (Boh.), a native insect of wild Solanaceae, has adapted to the medicinal plant Duboisia sp., introduced from Australia, causing damages up to 100% mortality. Microctonus sp. is the most important natural enemy of C. luridus and its potential for biological control was investigated in this work. This study was carried out in Arapongas, Paraná State, Brazil, from 1994 to 1996. Parasitism of C. luridus by Microctonus sp. was highest from February through June (maximum of 54% in May 1996), when the C. luridus adult population was decreasing. The female sex ratio of Microctonus sp. under natural conditions was 0.57 to 0.69, which was close to 1 male : 2 female. Production of males occurs parthenogetically (arrhenotoky). In the laboratory, parasitism reached 40% when two adult C. luridus were exposed per parasitoid. The number of Microctonus sp. adults that emerged per parasitized beetle ranged from 4.7 to 14.2. Larval-pupal viability was 31.7 to 64.8% and the female sex ratio ranged from 0.0 to 0.37, with prevalence of males. The egg-pupal period was 12.7 days and the pupal-adult period was 10.7 days, resulting in a mean life cycle (egg-adult) of 22.4 days for this parasitoid (25ºC, 70% R.H.). This is the first report of a new species of Microctonus sp. in C. luridus.
