The Population Biology of Chamaelirium Luteum, A Dioecious Member of the Lily Family: Two-Sex Population Projections and Stable Population Structure

Matrix projection models as typically applied to data from natural populations of an- imals and plants fail to distinguish between male and female contributions to population growth. The well-known Leslie model, for example, considers only females, and thereby ignores the interaction of females with males in the production of offspring. In the present paper, a two-sex size-specific population projection model is developed for Chamaelirium luteum, a long-lived dioecious plant. Application of this model to C. luteum is based on a 5-yr study of three large (N > 1000) natural populations of this forest-floor herb. Differences between sex classes (male, female, juvenile) in size- specific survivorship and size transitions are taken into account, as well as particular differences between males and females in age at first reproduction, flowering schedules, and reproductive output per individual. Projections of the three populations studied using this model generally showed a slight male bias in the adult sex ratio. Furthermore, comparison of observed size distribution and sex composition with projected stable populations indicated that the populations studied are near a stable structure and should show only modest changes in population size from year to year. These results are in accord with one's expectations for a long-lived species growing in an ecologically stable habitat.

A Pharmacognostical and Phytochemical Study of Maianthemum Canadense (Desf.)

A number of valuable plant constituents have been obtained from the Lily family and, therefore, Maianthemum Canadense (Desf.) was deemed worthy of investigation. The taxonomy, distribution, and habitat of Maianthemum Canadense (Desf.) are recorded herein. A study of the morphological and histological features of the leaf, root, and whole plant powder, and the phytochemical and pharmacological properties of whole plant extracts are also described.

MISCELLANEOUS BOTANICAL NOTES-IV*

1. In connection with the first record from Malaysia (Atjeh, North Sumatra)of a species of Schoepfia (Olacaceae), viz. S. fragrans Wall, in Roxb., some notes on the genus are given, including a key to the species of section Schoepfiopsis (emended) and to the two Indian species of Schoepfia.The specimens of the Kew and Leyden Herbaria of these two species are listed. The name Schoepfia ffriffithii Tiegh. is validly published in the present paper, if this was not done before. 2. Smilax pygmaea Merr. (Liliaceae) is recorded from Atjeh, Sumatra. 3. The first indigenous species of Mivmlus (Scrophulariaceae), M. tenellus Bunge,is recorded for Malaysia from Atjeh, Sumatra. 4. A new species of Macadamia (Proteaceae) is described from Celebes: Macadamia hildebrandii Van Steenis. It belongs to the same genus as the common Australian bush nut, M. ternifolia, with edible seeds. 5. Some information, additional to a previous paper on Biophytum (Oxalidaceae)in Malaysia, is given. 6. Some records of plants new to Mount Pangrango, West Java, are mentioned. 7. The recent introduction and the present distribution in Malaysia of the weed Eupatorium odoratum L. (Compositae) is discussed. 8. Some additional records of the liana Hollrungia aurantioides K. Schum.(Passifloraceae) from New Guinea and from outside this island (Ternate, Moluccas)are published.
