Klettaburknaætt – Aspleniaceae
Aðeins ein ættkvísl telst til ættarinnar og því óþarft að lýsa henni sérstaklega.

Klettaburknar – Asplenium L.

Flestar tegundir ættkvíslarinnar, sem eru um 700, eru ásætur eða vaxa í grjóti; aðeins örfáar lifa í mold. Jarðstöngullinn er mjósleginn, næringarlítill, og getur smeygt sér inn í hinar minnstu glufur. Blöðin eru yfirleitt mjög þurrkþolin. Gróbelttir eru flestir aflangir meðfram leiðsluvefjum; gróhula aflöng og fest á annarri hlið.
Margar tegundir ættarinnar eru ræktaðar í heimahúsum, ekki sízt í hengikörfum.

Greiningarlykill að tegundum:
1. Blöð kvíslgreind, mjög sjaldgæfur ……………………. skeggburkni (A. septentrionale)
1. Blöð fjöðruð …………………………………………………………………………………………….. 2
2. Blaðstilkur svartur-dökkbrúnn, einnig miðstrengur blaðs nema allra fremst ………….. …………………………………………………………………………. svartburkni (A. trichomanes)
2. Blaðstilkur brúnn neðantil, grænn ofantil eins og miðstrengur blaðs ……………………. ………………………………………………………………………………….. klettaburkni (A. viride)

Stilkur er um 7/10 af blaðlengd; grænn nema allra neðst er hann brúnn og vaxinn stuttum, glærum kirtilhárum. Blaðka er óreglulega kvíslgreind. Gróblettir dökkbrúnir, renna saman við þroskun og þekja nær allt neðra borð. Gróhula smábugótt á jöðrum.

Til gamans má geta þess, að höfundur fann klettaburkna í Kelduhverfi 1977, sem þá þóttu allnokkur tíðindi, því að hafði hann aðeins fundizt á Suð-Austurlandi. Maður nokkur tók sig til og skrifaði um þennan fund í tímaritið Týli að höf. fornspurðum áður en honum gafst ráðrúm til að skrifa um þetta sjálfur. Grasafræðingur á Náttúrufræðistofnun hóaði í samferðarmann höf. og bað hann um að segja sér nákvæmlega, hvar höf. hafði fundið tegundina, svo að unnt væri að merkja fundarstað inn á kort. Síðar var því hvíslað að höf., að þetta hefði verið gert, svo að þessir frómu menn þyrftu ekki að vitna í skrif höf. í sambandi við þennan fund.
