 »Annuum, caulis 4 — 8", e basi ramosissimus , ramis patentibus, ascendentibus, folia 

 omnia linearia, acutissima, umbellae 3 — 4-radiatae, radiis filiformibus; bracteolae acutae, 

 trinerves, fructu paulo breviores; umbellulae 3 — 5-florae; fructus ovati pedicello breviores, 

 mericarpia jugis acute 5-costatis.

Nota. Varietas humile sec. cl. Franch et speciraina parva B. Oerardii in memoriam 

 revocat, a quo praeter characteres sectionis involucelli phyllis prominenter 3-nerviis et pedicellis 

 gracilibus diflert; cum var. «., a qua habitu minore et foliis brevibus angustisque valde acuminatis 

 longe diversa, formis transitoriis conjuneta est; mihi proxima var. ß. khasiano vel forsan idem 

 esse videtur.
