本科約20屬250余種,產熱帶至亞熱帶,中國產15屬190種,主產長江流域以南。山茶屬Camellia山茶Camelliajaponica山茶為常綠灌木或小喬木,樹形和樹勢因品種不同而有差異。葉為卵形。倒卵形或橢圓形。長5-11cm,葉端短鈍漸尖.葉表有光澤,花單生或對生于枝頂或葉腋,大紅色。花瓣5-7，但也有重瓣的?；ò杲鼒A形頂端微凹,花期2-4月。分布：產于我國東南地區(qū)和日本。我國以浙江,江蘇,安徽,福建,江西,上海為最多。栽培歷史悠久，北方多盆栽。編輯ppt變種品種:已達3000以上,常見的變種有:

白山茶花白色白洋茶花白色,重瓣,6-10輪,外瓣大,內瓣小,呈規(guī)則的覆瓦狀排列.紅山茶花紅色,花型似秋牡丹,有5枚大花瓣,雄蕊有變成狹小花瓣.紫山茶花紫色葉呈狹披針形,有似百合的葉形玫瑰山茶花玫瑰色,近于重瓣重瓣花山茶花白色而有花紋,重瓣,枝密生,葉圓形.金魚茶花紅色,單瓣或重瓣,葉端三裂,如魚尾狀朱頂紅花型似紅山茶,但呈朱紅色,雄蕊2-4枚魚血紅花色深紅,花型整齊,花邊覆瓦狀排列,有時外輪1-2瓣帶白斑什樣錦花色粉紅,常有白或紅色的條紋與斑點,花型整齊,花瓣呈覆瓦狀排列編輯ppt編輯ppt品種分類:單瓣型托桂型半文瓣型全文瓣型武瓣型

習性:暖帶樹種,適宜于溫暖濕潤氣候,過熱過冷均不利于生長.在半陰半干情況下安全越夏,強烈陽光直射回引起葉面嚴重灼傷,在酸性,排水良好和深厚肥沃的砂壤,黃土和腐殖土三者混合中生長良好.山茶花對海潮風有一定的抗性.觀賞:山茶是中國傳統(tǒng)的名花,葉色翠綠而有光澤,四季常青,花朵大,花色美,品種繁多,從11月即可開始賞早品種花而晚花品種至次年3月開始盛開.故觀賞期5個多月.而這時正是花開少的季節(jié).常作庭院及室內裝飾.編輯ppt編輯ppt編輯ppt金花茶Camelliachrysantha常綠小喬木,干皮灰白色,平滑,葉長橢圓形至寬披針形,花黃色至金黃色，花期11月至次年3月變種:大葉金花茶常綠灌木高2-4米,葉橢圓形16-25cm,花黃色,產于廣西。小葉金花茶常綠灌木,葉長橢圓形至倒卵形橢圓形,長10-15cm,寬4-6cm,花淡黃色,果實蒴果,小1.5-2.5cm,花期10-11月,產于廣西。編輯ppt山茶類為世界著名花木，各國園藝界竟相爭奪國際市場發(fā)掘種質資源及更多更美的品種。過去對山茶花培育有三個目標，就是提高抗寒性，花具芳香，和黃色品種。前兩個目標早以實現(xiàn)，后一目標不容易實現(xiàn)。后來發(fā)現(xiàn)了金花茶，這樣三個目標均可實現(xiàn)。編輯ppt五加科Araliaceae
