Cycas lacrimans

Cycas lacrimans A.J.Lindstr. & K.D.Hill, "Telopea 12(1):136–138, fig. 5" (2008). H—NY
"TYPE: Philippines: Mindanao: Davao, Mati, Ramos & Edaño BS 48953, Mar–Apr 1927 (holo NY, iso BM, BO, P)."[NY]

Etymology: The specific epithet is from the Latin lacrimans, crying, in reference to the drooping or weeping habit of the leaves.

Historical notes: Although first collected in 1927 by Ramos & Edaño, this taxon was not recognised as a distinct species until 2006.

Distinguishing features: The long megasporophylls with reduced lateral spines, the seeds with no spongy endotesta and the lax, drooping leaflets distinguish this from all other Philippine species.

Distribution and habitat: Philippines, known at present only from hill forests of eastern Mindanao. Serpentine soil.

Conservation status: If restricted to this small area the species is in need of urgent protection in situ. Deforestation and other habitat destruction is extreme. IUCN (2001) Red List status EN.
