It can have a genetic predisposition for a specific allergy to start with. It can be repeatedly exposed to an irritating substance such as pollen when, at the same time, the body's mechanism for dealing with irritations is weakened. Generally weak adrenals causes this because the adrenal's job is to produce hormones that reduce inflammation.
For instance, a bulb of Hippeastrum aulicum produced four flowers; three were fertilised by Herbert with their own pollen, and the fourth was subsequently fertilised by the pollen of a compound hybrid descended from three other and distinct species: the result was that "the ovaries of the three first flowers soon ceased to grow, and after a few days perished entirely, whereas the pod impregnated by the pollen of the hybrid made vigorous growth and rapid progress to maturity, and bore good seed, which vegetated freely."
The sentries which guard the entrance to the hive pitilessly put to death the robbing bees which attempt entering the hive; but those stranger bees which come to the hive by mistake are left unmolested, especially if they come laden with pollen, or are young individuals which can easily go astray. There is no more warfare than is strictly required.
The perfumes of flowers have been developed so as to attract insects by the sense of smell, as their colours have been also developed to attract insects by the eye. The insects serve the flowers by carrying the fertilizing pollen from one flower to another, and thus promoting cross-fertilization among separate individual plants of the same species.
These, we perceive at once, are the work of starved, anaemic weavers, who, failing to satisfy their appetite and having eaten the last grain of pollen, have, before dying, done their best with their poor little drop of silk.
In unbalanced crosses of the genus Oenothera the hybrids of such reciprocal unions are often different, as we have previously shown. Sometimes both resemble the pollen parent more, in other instances the pistil-parent. In varietal crosses no such divergence is as yet known.
Pollen, and it will, it is hoped, prove a useful reference to the reader.
Water-dripping moss padded the lintels of grottos, before which dangled translucent ferns of delicate form, yet so rich and intense with life that crozier-tipped fronds took the hue of flowers coral-red, golden-bronze, and yellow; while golden dust clung to hairy undersides like pollen to the thighs of hive-returning bees.
At Mallicolo, on August 20, a horrible sight presented itself to the eyes of the two explorers when they walked inland with about eighteen most obliging and courteous natives an open space with four hollowed trunks of trees surrounding two stones, the trees carved into the shape of grotesque human heads, and among them, a sort of temple, made of sloping bamboos and pandanus leaves meeting at the top, from whence hung a dead man, with his face painted in stripes of red and yellow, procured, it was thought, from the pollen of flowers.
To meet him, Mrs. Ennis had asked her best, for the time being, friend, Mimi de Rochefort Mary was her right name and Mimi de Rochefort's best, for the time being, friend, Robert Pollen. Nowadays Pollen came when Madame de Rochefort came; one expected his presence. In the meeting of Pollen and Burnaby and Mary Rochefort, Mrs.
