Galphimia gracilis Batling. from Sunder Nursery, New Delhi, photographed on September 1, 2009
This small shrub is most confused and often sold in nurseries under the name G. glauca or sometimes G. brasiliensis. Last one is mainly a South American species also like G. gracilis with deciduous petals but easily differentiated by peduncles being absent or less than 2 mm long and smaller corolla limb (ca 4 mm long). G. glauca is distinct in having persistent petals often spreading below the fruit, longer and denser inflorescence, peduncle much shorter than peduncle (less than 1/2 as long) with bracteoles borne well below the tip of peduncle (peduncle 1/2 to almost as long as pedicel in G. gracilis; bracteoles at peduncle tip), shorter claw (1.5-2 mm in lateral petals, 3-4 in posterior, as against 2-2.5 in lat and 4-5 in post. petals in G. gracilis) and shorter fruit (2.5 mm long as against 4.5-5 mm in G. gracilis).
