|Helicia graciliflora Merr., Philippine Journal of Science 3 c (1908) Bot. 132.|
Synopsis: Known with certainty only from the type specimen collected by Mary Strong Clemens in September, 1907. It is distinguished by the thin papery leaves and the inflorescence stalk being very slender, hardly twice the breadth of the flower stalks, and the whole covered with a light red pubescence. Copies are found at least in B, BO, NY, L and K. Several digital images are available.
The specimen is not numbered and noted only as Camp Kiethley. Today, the site of Camp Kiethley on Lake Lanao lies within the completely urbanized center of Marawi City. However, the exact location of the collection is uncertain. Clemens referred to "Camp Kiethley" for plants that she collected within a days walk from the lakeshore, and for Mrs. Clemens, who would pioneer the botany of Kinabalu at the age of 65, a five kilometer walk was a mild stroll. Other collections from September 1907 include Vaccinium and Rhododendron and Medinilla, which suggests that she did at least once climb to some elevation. So, Helicia graciliflora might have been collected- and might still be found - on what is today Sacred Mountain National Park, a few kilometes north of Marawi City.
One other specimen is tentatively identified to H. graciliflora based on a duplicate at Kew: Philippine Plant Inventory 8550 on 10 August 1992, from Mt. Sayao on Biliran Island.
