The Dioscoreabuchananii complex is shown to comprise three species, one of which is divided into two subspecies, based on morphological data. Two species, Dioscorearupicola Kunth and Dioscoreamultiloba Kunth, are endemic or subendemic to South Africa and of widespread occurrence in KwaZulu Natal. They differ markedly from each other in inflorescence and floral morphology and appear to be ecolog...

Studies of the morphology of the corn plant have led, according to Weatherwax (17) j^ to clearer and simpler explanations of the results of certain experiments with corn. It should be expected that further studies of the developmental morphology might prove to be equally helpful. Variations from the normal sequence of development which lead to abnormalities of the tassel and ear and variations ...

DESPITE frequent contact, inhalation of grasses is a rare occurrence in childhood. In a high proportion of the recorded cases the inhaled foreign material was an inhaled inflorescence (flower or seed head) which had tracked through the lung parenchyma, the pleura and the chest wall, to present as a swelling, either in relationship to a rib or in the subcutaneous tissue. Jackson (1952) reported ...

The abnormal inflorescence meristem1 (aim1) mutation affects inflorescence and floral development in Arabidopsis. After the transition to reproductive growth, the aim1 inflorescence meristem becomes disorganized, producing abnormal floral meristems and resulting in plants with severely reduced fertility. The derived amino acid sequence of AIM1 shows extensive similarity to the cucumber multifun...

Aratitiyopea lopezii is a robust perennial species of Xyridaceae from seasonally saturated, midto high-elevation, sandstone and granite sites in northern South America. The species lacks the scapose inflorescence characteristic of Xyridaceae and, having the gestalt of a rhizomatous bromeliad, it is seemingly aberrant in the family. However, closer examination confirms features consistent with t...

From the flowers of meadowsweet and inflorescence of hawthorn the whole set of phenolic acids and flavonoids was analysed by TLC. Phenolic compounds were determined both as free ones and those liberated by hydrolysis. Moreover, ethyl ether and ethyl acetate extracts obtained from the analysed plants before and after alkaline and enzymatic hydrolyses were evaporated under reduced pressure and re...

Bagging of female inflorescence following pollination has recently received growers attention. Although this process occurs early in the season but affects fruit quality, yield, and marketability. Date palm growers have used to use grocery paper bags for this bagging process. Since inflorescence bagging causes what is called the greenhouse effect, it was very important to investigate the effect...
