In gmnr, so far a total of 1030 vascular species in 536 genera of 169 families have been listed, 141families, 486 genera, 949 species ( including intermination taxa, similarity hereinafter ) of the spermatophyta, including 4 families, 4 genera, and 7 species of the gymnospermae, and 137 families, 482 genera, 942 species of the angiospermae - - - - - - the dicotyledonae 117 families, 374 genera, 755species, and the monocotyledonae 20 families, 108 genera, 187 species
本文是對廣東省古兜山自然保護區種子植物區系的組成與基本特點的研究，現知古兜山共有野生維管植物169科536屬1030種（
蕨類植物28科50屬81種，裸子植物4科4屬7種，雙子葉植物117科374屬755種，
單子葉植物20科108屬187種） ，具有部分古老孓遺種，以木本植物為主，其次為草本，藤本不多。
Next, the difference between two systems is the range of genera. for example, the view of kato and sano, deparia include five genera of ching ' s system : dryoathyrium, lunathyrium, athyriopsis, diplazium, dictyodroma
如根據kato和sano的觀點， deparia包括秦仁昌（ 1978 ）系統中的五個屬：介
蕨屬、蛾眉
蕨屬、假蹄蓋
蕨屬、
單葉雙蓋
蕨屬、網
蕨屬。
Researches indicate that, within a background of less complex, cosmopolitan zosterophyll and trimerophyll taxa, the posongchong flora has some plants with complex combination of morphological and structural characters, showing more advanced level of fertile and sterile organs than those found in contemporaneous land vascular plants from laurussia
研究表明坡松沖植物群在某些簡單的、常見的工蕨類植物和三枝蕨類植物組成的背景下，含有具復雜形態和結構特徵的植物類群，顯示了較勞亞大陸同期陸生維管植物更進化的營養器官、生殖器官分異的水平。
