Solanumdiphyllum L. and MalvaparvifloraL.reported as new distributional records for Bihar. A brief description, photographs and distribution are provided for both taxa.
Malvaceae, Solanaceae, new record, Bihar.
During the recent botanical exploration to Bhagalpur district, Bihar the authors found two interesting plants in two different parts of district. Malvaparviflora L. (Malavaceae) was growing in a Bara Chaur, Narayanpur, Bhagalpur and Solanum diphyllum L. (Solanaceae) was growing in university campus, Bhagalpur. On critical examination and perusal of literature [1,2,3,6,810,11,12] revealed that both plants were never reported from Bihar before.

Flowering & Fruiting: March – July
Exsiccatae: Bihar: Bhagalpur, T.N.B. College campus, University road, 5.4.2013, S. Halder& G. Krishna 53863(CAL).
Distribution: INDIA [Assam, Bihar, Karnataka, Maharashtra, Tamil Nadu and West Bengal], Mexico, Costa Rica, El Salvador, Guatemala, Honduras, Nicaragua.
Note: Solanum diphyllum L. (Solanaceae), a native of Mexico and Central America has been naturalised in India. Paul Biswas  recorded this plant as new addition to Indian flora from Howrah, West Bengal. Later Maity et al  and Reema Kumari  documented it as a new addition for flora of Assam and peninsular India respectively. While working on flora of Bihar, authors have collected the specimens from Bhagalpur district which turns out to be a new addition for Bihar.
