A name for common words that use uncommon kanji?


I didn't see a duplicate for this in the similar questions, so here goes. Is
there either a list of words like this, or a name for this type of word (made
of two very rare/complex kanji, but the word itself is fairly common)?

These are the ones I have so far, for reference:

> 癇癪{かんしゃく}  
>  躊躇{ちゅうちょ}  
>  顰蹙{ひんしゅく}

These two are just plant/mineral names, but are also somewhat common/Jouyou
kanji:

> 薔薇{バラ}  
>  瑠璃{ルリ}




> ... a name for this type of word (made of two **very rare/complex kanji, but

How about...  
「読めるけど書けない漢字」  
or maybe...  
「読めるけど書けない(二字)熟語」

such as:  
薔薇、憂鬱、蒟蒻、痙攣、葡萄、贔屓、曖昧、檸檬、麒麟、挨拶、絨毯、凱旋、潰瘍、魑魅魍魎
