Abstract Fourteen Families, 21 genera and 23 species have been described in this work, as motifs identified on the ancient wooden carved and painted vases known as keros. These date from the early colonial or transitional epoch between the pre-conquest Inca styles and those coming later with very strong Spanish influence. Although many of the well-known food, medicinal, ornamental and ritual plants are depicted, a large number of plants known to the Incas, both wild and cultivated, is absent. Certain motifs have been impossible to identify, but it is hoped that future studies may throw considerable light on the decorative and symbolic motifs in this interesting group of vases. food plants, Inca culture, keros, medicinal plants, plant motifs Footnotes * Translation by J.

Abstract The discovery is reported of a new endemic species of wild rice in series Sativae from northern Australia, Oryza meridionalis Ng. This species has previously been confused with O. rufipogon, O. nivara and O. sativa f. spontanea. Its geographical distribution is confined to northern Australia. It is also reproductively isolated from all other species of the series Sativae. Oryza, taxonomy, wild rice REFERENCES CHANG , T. T. , OU , S. H., PATHAK , M. D., LING , K. C. & KAUFFMAN , H.

Abstract Thrasya paspaloides Humb., Bonpl. & Kunth (Gramineae, Paniceae) is considered with respect to its status as the type species of its genus. Errors in Kunth's original description are identified and analysed in the light of opinions formed by Trinius and Nees; and by analogy with plants from collections subsequent to the type collection; morphological characters are discussed, and data provided for a comparison with the related species T. thrasyoides (Trin.) Chase and T. trinitensis Mez, with which T. paspaloides is commonly confused. The geographical distribution of the three species is examined, together with the habitat. The conclusions are used to support proposal of a modification of the description of T. paspaloides and the selection of a lectotype. distribution, Gramineae, lectotype, morphology, Paniceae, Poaceae, taxonomy, Thrasya REFERENCES CHASE , A. 1911 .

Comparative developmental morphology of two populations of Ceratophyllum L. (Ceratophyllaceae) and their taxonomySEHGAL,, ANITA;RAM, H. Y., MOHAN
doi: 10.1111/j.1095-8339.1981.tb00966.xpmid: N/A
Abstract Developmental morphology of two natural populations of Ceratophyllum inhabiting the waters of Delhi has been investigated under natural conditions and in aseptic culture. Both the populations show an extreme degree of adaptability to hydrophily. The embryo is unusually highly developed and contains 12–14 whorls of leaves and a few lateral buds. The two populations differ significantly in colour and dichotomy of leaf; structure and position of male flowers; number, position and colour of horns on the fruit; stylar length and distribution of sexes. The latter two parameters are probably responsible for the reproductive isolation of the populations, despite their sympatric association. On account of these differences, the two populations are assigned to two distinct species C. demersum L. and C. echinatum Gray, respectively and their taxonomy is discussed; C. echinatum is a New World species not previously recorded from India. aquatic weeds, Ceratophyllum, developmental morphology, hydrophily, population biology, taxonomy REFERENCES BISWAS , K. & CALDER , C.

Alien plants in central AustraliaBUCKLEY,, R.
doi: 10.1111/j.1095-8339.1981.tb00968.xpmid: N/A
Abstract The central Australian flora currently contains 78 alien species, of which 17 are predominantly summer-growing, 19 are southern winter-growing species reaching roadsides, stockyards and watercourses in the southern Northern Territory and 42 are at present confined to gardens in Alice Springs. A further 11 species reach the far north of South Australia or the far southwest of Queensland but not the Northern Territory. The central Australian alien flora may be classified by growing season and drought-tolerance, or broadly categorized on the basis of habitat and dispersal agent into ‘garden weeds’, ‘tourist weeds’ and ‘stock weeds’. Present ecological knowledge of central Australian aliens is limited, but indicates that whilst some will probably remain confined to better-watered habitats, many are likely to spread into the arid areas, becoming obvious only after a succession of wet years. The central Australian alien flora is increasing at present and this increase is expected to continue. aliens, central Australia, Northern Territory, weeds REFERENCES ANONYMOUS 1969 .

The diversity of stomatal development in Orchidaceae subfamily OrchidoideaeRASMUSSEN,, H.
doi: 10.1111/j.1095-8339.1981.tb00969.xpmid: N/A
Abstract The development of leaf stomata in species of Orchidoideae sensu Garay is agenous or hemimesogenous with a single mesogene cell. Both kinds of development occur in all 26 species studied and are found in a characteristic proportion which may differ markedly even between related species. Leaf and stem stomata develop similarly but surrounding cells may divide obliquely in the latter, so that perigene cells are formed. At maturity, mesogene and perigene cells resemble other epidermal cells, the stomata being anomocytic. In monocotyledons, the hemimesogenous development of stomata is previously known only from five orchid genera of the neottioid tribe Cranichideae sensu Dressler. This kind of stomatal development in monocotyledons is documented by micrographs for the first time. Mesogene and perigene cells are recorded for the first time in the Orchidoideae. The diversity of types of stomatal development in this group is emphasized. Orchidaceae, Orchidoideae, stems, stomatal patterns REFERENCES BÜNNING , E. & BIEGERT , F. 1953 .
