PLANT FAMILY: Costaceae
BOTANICAL NAME: Costus pictus 'Hieroglyphics'
FORMAL SCIENTIFIC NAME:
STATUS :
CONTINENT: Neotropical
SYNONYMS:


BOTANICAL NOTES:
Costus pictus in the form with the patterned stems is sometimes referred to as Costus heiroglyphicus or similar name. The registered cultivar name is 'Hieroglyphics', established by Glenn Stokes publication in his plant catalog. Stokes told me he received the plant fro Thomas Wiedeman in Costa Rica, but Tim Chapman has told me that this form has been in cultivation in the US for many years before it appeared in the Stokes Tropicals catalog.

While checking Costus ID's at Waimea Arboretum (Hawaii) with David Orr, we came across their accession #84P452, which they had listed as "Costus sp.". This is the form of Costus pictus that is common in horticulture with the patterned stems, sometimes called "Costus hieroglyphica". We looked up the accession data and found that their specimen was received in 1984 from the USDA Subtropical Horticulture Research Station in Miami, Florida. There is the notation that this plant was "collected by Jack Reark in the Black Creek Area of Belize." This may be the original source of this form of Costus pictus that is common in horticulture.

This form is consistent with Maas' description of the species having green, non-appendaged bracts with inconspicuous nectar callus, open type flowers with yellow corolla and red-striped labellum, and short ligules. It sometimes flowers at both the base on nearly leafless stems and terminally on normally leafy stems. The nectar callus on the bracts of this form are visible but somewhat indestinct (as described by Maas) being a dark green color against the lighter green of the bracts.

The cultivar registration description: Described in catalog as follows: We have dubbed it "Hieroglyphics' because of its interesting and busy pattern of red markings on the stems. It may be related to Costus pictus. It grows 7' (2.1m) to 8' (2.4m) in medium to full sun. Like pictus it produces both terminal and basal cones. Has rather thin stems and narrow leaves. Obtained from Costa Rica. Strikingly marked stems and cone inflorescences make great cut flowers. This plant is widespread in cultivation sometimes found under slightly different spelling. It can further be distinguished by the long stiff hairs at the ligules and the undulating form of the leaves.

ACCESSION NOTES:
R1572 purchased from a local nursery. This collection has been vouchered at the UC Berkeley, Jepsen Herbarium, UC2045787.

R1818 received as a "volunteer" with another plant received in trade. The 'Hieroglyphics' form of C. pictus has proven cold hardy in USDA zone 8.
