It is plausible that specialized ecological interactions constrain geographic ranges. We address this question in neotropical bees, Centris and Epicharis, that collect oils from flowers of Calceolariaceae, Iridaceae, Krameriaceae, Malpighiaceae, Plantaginaceae, or Solanaceae, with different species exploiting between one and five of these families, which either have epithelial oil glands or hair fields. We plotted the level of oil-host specialization on a clock-dated phylogeny for 22 of the 35 species of Epicharis and 72 of the 230 species of Centris (genera that are not sister genera) and calculated geographic ranges (km(2) ) for 23 bee species based on collection data from museum specimens. Of the oil-offering plants, the Malpighiaceae date to the Upper Cretaceous, whereas the other five families are progressively younger. The stem and crown groups of the two bee genera date to the Cretaceous, Eocene, and Oligocene. Shifts between oil hosts from different families are common in Centris, but absent in Epicharis, and the direction is from flowers with epithelial oil glands to flowers with oil hairs, canalized by bees' oil-collecting apparatuses, suitable for piercing epithelia or mopping oil from hair fields. With the current data, a link between host specialization and geographic range size could not be detected.

“…In summary, the unusual mirror‐image flowers and heteranthery associated with longitudinally dehisced anthers and extremely reflexed petals in H. benghalensis probably reflect a remarkable floral specialization to facilitate pollination by pollen‐collecting honeybees that do not carry out buzz pollination. Such floral evolution and pollinator shift appear to be distinctive in Malpighiaceae (Davis et al ., ; Cappellari et al ., ) and have important implications for the evolutionary adaptations of flowers under selective regimes with different pollinators (Ramirez, ; Arditti et al ., ). These findings can help to explain the evolutionary adaptations of Malpighiaceae during its long‐distance dispersal from tropical America to Africa and Asia (Davis et al ., ; Anderson et al ., ; Zhang et al ., ).…”

Mirror-image flowers without buzz pollination in the Asian endemicHiptage benghalensis(Malpighiaceae)

2013

Mirror‐image flowers represent a highly specialized pollination system that is normally associated with poricidal anthers and buzz pollination (pollen can be only released from anthers via pollinator vibration). In the Asian endemic Hiptage benghalensis (Malpighiaceae), mirror‐image flowers were found with longitudinally dehiscing anthers and such floral syndromes are firstly reported in the family. We investigated the floral biology and frequencies of left‐ and right‐styled flowers of H. benghalensis in Hainan Island, southern China. We conducted pollination manipulations to determine breeding systems and studied the pollination mechanism. We also examined the compositions of the secretions of the calyx gland. Controlled pollinations revealed that H. benghalensis is self‐compatible. Left‐ and right‐styled flowers are produced in the same inflorescence and a 1:1 ratio is found at both plant and population levels. Flowers have extremely reflexed petals, zygomorphic corollas and a single but oversized calyx gland. This gland secretes sugars and mainly attracts ants and wasps in both blooming and fruiting periods. Heteranthery is obvious with one large stamen producing more viable pollen than the nine small stamens. All anthers dehisce longitudinally and pollen grains readily adhere to floral visitors without the need of buzz pollination. The unusual association of mirror‐image flowers with longitudinal anthers probably reflects an adaptation to local pollen‐collecting (but non‐buzzing) honeybees such as Apis dorsata. These results indicate that floral syndromes and pollination adaptation in H. benghalensis differ completely from the New World Malpighiaceae and may help to explain evolutionary adaptations of the family during its long‐distance dispersals from the New World to Asia. © 2013 The Linnean Society of London, Botanical Journal of the Linnean Society, 2013, 173, 764–774.

“…In most Hiptage species, no or only one calyx gland is present (Chen and Funston , Ren et al , Ren ), but in H. lushuiensis two obvious calyx glands are visible and in some individuals additional smaller calyx glands can be found (Fig. G–H), suggesting that H. lushuiens is at an intermediate position in the evolutionary reduction of calyx glands (Cappellari et al ).…”

“…The calyx gland is a unique floral trait in Malpighiaceae (Anderson , , Ren et al ) and is important for taxonomical studies of the family (Anderson et al , Cappellari et al , Ren et al ). In Hiptage , calyx glands produce nectar (Ren et al ) and the number of calyx glands is greatly reduced as compared with American members of the family, in which the calyx glands secrete oils (Anderson , Davis and Anderson ).…”

Hiptage lushuiensis, a new species from the Hengduan Mountains, northwestern Yunnan Province, China, is described and illustrated here. This species was found growing at the margin of an open forest in the Nujiang Gorge of Lushui City. Hiptage lushuiensis is distinctive for its pink petals, 2 or more calyx glands, and large and pink samara with white hairs. This species is isolated in the deep gorge (25°51′N, 98°51′E, altitude 917 m), at the northern edge distribution range of the genus. These distinctive morphological differences and the geographic isolation suggest a history of long‐distance dispersal and allopatric speciation. Hiptage lushuiensis has a shorter filament but larger herkogamy than related species, suggesting that H. lushuiensis may have adapted to other pollinators with short but fat body such as Amegilla or Bombus spp.
