野蘭野蘭我愛您之二
尋日朝早帶麻煩去潟湖「晨運」,順便勘察其他地生蘭生長情況,不過依然未有 Orchis collina 以外嘅蹤影~ 老公知我渴望賞蘭,於是提議向 El Burgo 出發,沿途我都打醒精神,睇到有疑似蘭嘅物體或可能適合地生蘭生長嘅地段,我都叫停落車,展開「地毡式搜索」.... 雖然天陰有雨,能夠見到兩種之前未見過嘅品種,心情實在興奮!
Orchis olbiensis, 上年晌 El Torcal 附近已經見過
Ophrys picta, 屬於蜂蘭 scolopax 組別,第一次見!!!之前見過呢組內另一品種
估係 Ophrys lupercalis,屬於蜂蘭 fusca 組別,第一次見!!!眾多不同 dark bee orchid 品種實在分別細微,我並非專家,認錯機會好大!
呢個週末因為天災人亡關係,氣氛不免沉重,藉著欣賞大自然嘅美麗與巧妙,希望心情得以舒緩一下!
Ophrys 蜂蘭嘅少少介紹(節錄自維基百科)
Orchids of the genus Ophrys use sexual deception to attract pollinators to their flowers. In sexual deception, an orchid attracts male pollinators by producing the sex pheromone of virgin female pollinators in addition to providing visual and tactile cues. These signals stimulate mating behavior in the male pollinators, which then attempt copulation, called “pseudocopulation”, with the orchid labellum. During pseudocopulation, pollen from the flower’s column becomes attached to some part of the pollinator, usually the head or abdomen, and the pollinator inadvertently carries and transfers this pollen to other flowers when they are once again enticed into pseudocopulation. While the morphological cues such as the shape and texture of the labellum play a role especially at close range in inducing the pollinator mating behavior, the orchid’s pheromone mimic, or allomone, has been shown to play the most important role in enticing the pollinators to the flower.
The allomone produced by an orchid is specific for its pollinator, of which it usually only has one. The allomone is a mixture of alkenes and alkanes. There are one or more active species in this mixture that account for the attraction of pollinators. Pollinators and orchids use the same chemical compounds in the same absolute amounts in their pheromones and allomones, respectively.
The Bumblebee Orchid (Ophrys bombyliflora) is a typical example. It has flowers that look and smell so much like female bumblebees that males flying nearby are irresistibly drawn in by this chemical signal, stimulating them sexually. The insect gets so excited that he starts to copulate with the flower. The firmness, the smoothness and the velvety hairs of the lip are a further incentive for the insect to enter the flower. The pollinia inadvertently stick to the head or the abdomen of the male bumblebee. On visiting another orchid of the same species, the bumblebee pollinates its sticky stigma with the pollinia. The filaments of the pollinia have, during transport, taken such a position that the waxy pollen are able to stick to the stigma. Such is the refinement of the reproduction. If the filaments hadn’t taken the new position, the pollinia could not have pollinated the new orchid.
Every Ophrys orchid has its own pollinator insect and is completely dependent on this species for its survival. Furthermore, duped males are not likely to return. They even ignore other plants of the same species. Therefore, only about 10% of an Ophrys population gets pollinated. This is enough to preserve the population, since each Ophrys orchid produces about 12,000 minute seeds.

那天再重聚
上年尾嘅香港行內,包含咗一個我期待咗一年嘅聚會-12/18 中學母校舊生大團聚-呢個活動之所以能夠「誕生」,臉書可謂功不可沒!
我嘅中學母校已經晌 1994 年結束,佢係跟隨香港學齡兒童人口轉型嘅產物:1977年9月,一間六層官小校舍,五層係小學生用,而第六層就係三班中一用;我係1979年入讀,第三屆,當時已經再無小學生嘞;1984年我中五畢業,而母校亦係第一年同另一間應該都係官小變官中嘅學校合辦預科班,不過母校係辦理科,我地文科三班嘅同學(除咗重讀中五嘅),都一定要同母校講拜拜;至1994年母校終於難逃「殺校」命運,初期好似改為教育局 office,而家又改返成小學。好一個循環!
自己由畢業後同大約十多個舊同學一直有聯絡,隨住年月同人海飄流,從最初一年兩次十三、四人嘅活動至近年最多四、五人一年一聚.....不過仍要感恩擁有廿多年嘅友誼。
2009年中晌臉書嘅 group 功能內用母校嘅名去搜尋,竟然已經有校友開咗個舊生 group,我當然立即加入,而且短時間內仲「重遇」幾個同級嘅同學。或者因為母校已經不再存在,我地返而對佢更加懷念,呢個 alumni FB group 有五百幾成員,係母校歷年學生總人數差不多三分一。而2009年尾終於有校友發起攪個 mega reunion,大家利用臉書作為號召聯絡人手嘅平台,之後 organising committe 成立、開會、策劃、各種行動,臉書理所當然地成為分享資訊、相片、進度嘅工具之一。
2010-12-18 我終於見到唔少廿多年無見嘅面孔,興奮之情今日仍然歷歷在目!

終於開爐
上星期開始,太陽落山後室內陰陰凍,係時候要加啲温暖...... 之前十年都住有 radiators 嘅屋,首個冬天日日點火起爐..... 不過可能會換個有門又燒 pellets 嘅,暖啲又乾淨啲!

對鏡理紅妝
從來購買擺件時都只係諗住用嚟擺
尤其呢啲得個樣嘅中式嘢(某人晌上海買嘅)
勢估唔到竟然會有用得著嘅一日!
話說搬屋之後兩個茂李兩個星期都冇照過鏡,因為未買浴室鏡.... 某日見到呢個東東突然記起係有面鏡晌裏面嘅,即刻拿拿臨睇下個貓樣,驚覺原來雙眉「雜草叢生」!嚇親街坊多時!
