This chapter focuses on a single flower scent—the tuberose—strongly associated with the fragrance of Victorian decadence. Contrasting with the more delicate scent of the violet explored in Chapter 2 is the powerful perfume of the tuberose, an exotic hothouse flower, its fragrance evoking the body and decay. Starting with Shelley, this chapter tracks this heady fragrance through a range of texts to concentrate on three poems by late Victorian minor poets—Mark André Raffalovich, Mary Robinson, and Theodore Wratislaw—and shows how the scent of the tuberose is bound up with dangerous or voluptuous pleasures, with love, eroticism, criminality, and death.

Six populations of apparently morphologically similar sessile-flowered Trillium (known taxonomically as T. cuneatum Raf. and T. luteum (Muhl.) Harb.) observed growing at elevations between 800 and 1700 ft in the Appalachians of western North Carolina and eastern Tennessee exhibit a wide range of variability by observation. The extent of variability was assessed by using statistical and karyotypic methods of analysis and by intraspecific cross-pollination. A correlation exists between the mean coefficient of variability and (1) the size of the population and (2) the degree of geographic isolation. The number of types of each kind of chromosome (A–E), as resolved by cold treatment, varies by one type from population to population. The homozygosity for the six populations is 85.8%, and the distribution of euchromatin is not complex. Intraspecific cross-pollination was effective among 76% of the test crosses. A review of the statistics and other morphological data indicates that the presence or absence of anthocyanins, flower scent, and the degree of geographic isolation are the three major variants among the six populations. These kinds of Trillium grow sympatrically with T. grandiflorum (Michx.) Salisb., T. simile Gleason, T. erectum var. album (Michx.) Pursh, T. flexipes Raf. (T. gleasoni Fern.), and T. erectum L. The cumulative karyotype for the six stands indicates that these plants have not hybridized with any of the above species and varieties. Although these plants have been classified as T. cuneatum Raf. in some stands and as T. luteum (Muhl.) Harb. in others the data demonstrate that these six stands represent one discontinuous population of a sessile-flowered Trillium. Trillium discolor Wray, although relatively rare in western North Carolina, also grows here. Although T. discolor is not directly involved in this problem, its description and distinctive karyotype are included.

Floral Oil

The chemistry of the floral oils of Phymatidium delicatulum and P. tillandsioides (Orchidaceae) is described. These small epiphytes produce the oils in a complex gland (the elaiophore) located on the median petal. The floral oils of P. tillandsioides were shown to be comprised mostly of acylglycerols, as in many other Oncidiinae orchids from southeastern Brazil. Surprisingly, the floral oil of P. delicatulum was composed, predominantly, of relatively simple linear hydrocarbons. Evidence that P. delicatulum is pollinated by females of the oil-gathering bee genus Tetrapedia (Apidae: Tetrapediini) is presented.

Pollinator Rewards

Floral oils as reward to pollinators occur in eleven plant families and appeared at least 28 times in the evolutionary history of flowering plants. They are produced in epithelial or tricomatic glands and collected by oil bee visitors. The present paper focuses on floral-oil-producing species of Plantaginaceae, a Neotropical group namely Angelonia clade. This group comprises around 40 described species in the genera Angelonia, Basistemon, Monttea, Monopera and the oil-less Melosperma. We present a revision of all species of the Angelonia clade, their geographical distribution, resources offered to pollinators and records of flower visitors, especially oil-collecting bees. These plants rely only on oil-collecting species in the tribe Centridini and Tapinotaspidini for a successful pollination, being the interaction between both partners an especial case of bee/flower adaptation in Neotropical region. Some bee species depend only on the oil of Plantaginaceae flowers to survive, while others can collect on several floral oil sources. The pollinating bees explore the oil glands located in sacs using specialized hairs in the forelegs. With this study, we hope to inspire further research relating to this fascinating group of plants, in which most species are rare and occur in highly endangered habitats in South American open vegetation biomes.
