本文以台灣山螞蟬族(Desmodieae) 中十二個屬三十四種植物的花粉為材料,應用光學及電子顯微鏡來觀察花粉外 部形態及內部層次構造中所展現的特徵差異,這一族植物的花粉形態變異很大, 雖然都是三溝孔粉,但外壁花紋及層 次結構在種與種之間卻各異其趣。 山螞蟑族植物之花粉依目前所觀察的結果,由外部形態及層次結構將其分為六個類型。第一類型:外壁租網紋, 明顯雙緣溝, 具孔蓋似的構造,單純的圓柱層並無孔間顆粒存在。第二類型又分兩種亞型﹒ A外壁皆為粗網紋, 雙綠 溝,溝緣外壁雕紋侃細穿孔,溝孔處有細顆粒覆蓋, 基層則逐漸消退; B外壁細網紋, 壁層沒有很丸細管道及柱間顆粒, 最內層厚度大增o 第三額型外壁具租瘤狀突起, 蓋頂明顯半圓紋。第四類型﹒外壁微細穿孔或具有輕微的網狀散條 紋, 基層不連續或逐漸消退。第五類型:外壁皆細網紋, 基層不連續, 最內層厚度與蓋頂相當。第六類型:外壁具微 細穿孔,圓柱層被柱間顆粒取代,基層消失。 分類學者比較各屬問之外部形態, 將山螞握族又分為三個亞族, 台灣僅產兩個亞族即螞捏亞族及胡枝子亞族, 但 是由花粉形態上的差異來看,反在其間尋到一些相似性,可能是演化的過程中適應環境而在外部形態上產生變化, 內 部構造如花粉粒卻未及改變而保持相似的特徵。
The pollen morphology of 12 genera and 34 species belonging to the Desmodieae in Taiwan was stlldied by light microscope, scanning electron microscope and transmiss ion electron microscope. The great variation in pollen characteristics among these plants was examinecl. According to pollen morphology and exine stratification, the po l1巴n grains can be clivided into six types. (1) The tectllm is coarsely reticlllate and di stinctly l11arginate on colpi aJ margins. It has opercllllll11-like structure. Th 巴simple colll l11el1ae have no granular interstiti l1m. (JI ) This type is divided into two sllbtypes. (a) The tectum is finely reticl1 late, l11arginate and microperforated; the colpus membrane is finely granulate; and the foot layer is redllced. (b) The tectllm is reticlllate, and it has no l11icrochannel and gran l1 lar interstitilll11. The endexine is thicker than the tectll l11. (II1) Th 巴 t巴cWm is coarsely verrllcat巴0 1' weakly rug111ate. Only the poll 巴n of Alysicarpus sp. has mesocolpial pouches parti aJ ly covering the encloapertures. (IV) The tectl1m is microperforated or weakly ruglllate; and the foot layer is di scontinuol1s and redllcecl. (V ) The tectum is finely reticlllate; the foot lay巴r is thin and c1 iscontinllOl1s. (VI) The tectllm is micropelforated; the columel1ae are replac巴d by gran111ar interstitillm; and there is no foot layer.
