日本におけるダイズアブラムシの生活環

1) 日本でのダイズアブラムシの生活環は野外観察と飼育実験から,クロウメモドキ属のクロウメモドキ,クロツバラを一次寄主とすることを明らかにした。2) ダイズアブラムシの生活環と一次寄主の落葉期,萌芽期との同調性について考察した。3) これまで記載のなかった,ダイズアブラムシの幹母,幹雌,産卵雌虫と雄ならびに簡単な記載だけだった産雌虫を図示し,ワタアブラムシと比較して記載した。

The isolation and structure of three new lignans from Justicia procumbens Linn. var. leucantha honda

Six lignans were isolated from Justicia procumbens var. leucantha. Three of them, neojusticin A (V) and B (VI) and taiwanin E methyl ether (IV), are new compounds; the structure VI was verified by comparison with a synthetic sample. The others were justicidin A (I) and B (II) and diphyllin (III). Neojusticin A and B are the first examples of naturally occurring 1-oxygenated-2,3-naphthalide lignans.

REMARKS ON THE POSITION OF SOME AUSTRALIAN ACANTHACEAE

The taxonomic position of some Australian Ruelliinae and Justiciinae is discussed. In Dipteracanthus two new combinations are proposed, viz. D. primulaceus (F. v. Mull, ex Bth.) Brem. and D. corynothecus (F. v. Mul, ex Bth.) Brem., both originally described in Ruellia, and one new species and one new variety are described, viz. D. sessiliflorus Brem. and D. corynothecus (F. v. Mull, ex Bth.) Brem. var. grandiflorus Brem. The Australian specimens that hitherto have been referred to Justicia procumbens L (= Rostellularia procumbens (L) Nees) will have to be referred to various other Rostellularia species. Justicia kempeana F. v. Mull, is removed to a new genus Sarojusticia, which necessitates the new combination S. kempeana (F. v. Mull) Brem.
