General DescriptionGigantic suckering herb to c. 3 m tall, usually with one crown strongly dominant but eventually forming a clump of large crowns. Leaves several together, hastate to sagittate; petioles to 2.5 m long, irregularly and obliquely mottled white, green brown and pink, heavily armed with the spines coalescing into oblique combs; costae bright pink in young specimens, later with the laminas blotched reddish brown beneath and the costae green to brown; posterior lobes somewhat exceeding the anterior, to c. 70 cm long; peduncle similar to but shorter than the petioles. Spathe deeply and narrowly boat-shaped, 9-c. 40 cm long, rather abruptly more deeply and narrowly concave in the upper portion, erect, dark purple outside, pale dirty yellowish green within; spadix 7-25 cm long, with a short free stipe, somewhat glaucous; flowers hexamerous; anthers exserted at male anthesis; ovary 1- to 2-ovulate; fruit and seed unknown.DistributionKnown only from and widely distributed in cultivation, and said to have been introduced from the Solomon Islands. There are no collections which can be said with confidence to be of this species and from wild plants. However, Waterhouse 42-B (K), is from a juvenile plant collected at Hapan, Buka Island in 'open country'. Buka Island lies at the north-western end of the Solomon Island Chain. The specimen is labelled Caladium, suggesting that it may have had pink coloration in the leaf.DiagnosticStamens exserted from the tepals at male anthesis; flowers hexamerous; Petioles and undersides of laminae with reddish-brown blotches; juvenile leaves with pink costae.
