C. Jeffrey’s scientific contributions

... still remains valid at the end of the second decade of the current century. Heywood (1984) considering the design of Floras for the future two interrelated aspects have to be considered: (1) the purpose of Flora and audience aimed at, (2) technical aspects of data presentation in a computer oriented world. ...

... An excellent review of the systematic applications of palynology in the plant kingdom has been provided by Erdtman (1943) and examples of the usefulness of the pollen characters in delimiting plant taxa are given by Cerceau-Larrival (1971) in the Umbelliferae and Skvarla and Turner (1966) in the Compositae; Erdtman and Metcalfe (1963) gave an example in which palynology and anatomy could be used to solve a taxonomic problem; and Jeffrey (1964) used pollen morphology to establish a new system of classification in the Cucurbitaceae. The size and shape of pollen and spore (the principle characters), are being increasingly used in systematic studies along with type, number and position of the apertures and pollen wall architecture (Heywood, 1976). Thus, in our present communication, detailed pollen morphometric analysis with the aid of light microscope (LM) and field emission scanning electron microscope (FESEM) on four basal Bougainvillea species and their 22 Indian varieties was performed for the comparison of already generated, addition and refinement of palyno-morphological data. ...
