The effects of floral display on pollinator visitation vary among populations of Phacelia linearis (Hydrophyllaceae)
-
Description
-
Individual plants in gynodioecious populations of Phacelia linearis (Hydrophyllaceae) vary in flower gender, flower size, and flower number. This paper reports the effects of variation in floral display on the visitation behaviour of this species' pollinators (mainly pollen-collecting solitary bees) in several natural and three experimental plant populations, and discusses the results in terms of the consequences for plant fitness.

Tricks of the Trade: Getting Going the First Day, Statistics in the Liberal Arts Workshop (SLAW), Technical Report No. 94-003
-
Description
-
What can we do the first day of class to give students a feel for what to expect in the course and generate some enthusiasm for learning and statistics? To investigate this question, a number of prominent statistics educators were recently asked "What do you like to do in your first class of the semester"? Their responses and experiences of the author are summarized in this paper to provide a collection of tips, stories, topics for generating discussion, and general advice for getting a course going in a positive direction.

Wood Anatomy of Darwiniothamnus, Lecocarpus, and Macraea (Asteraceae)
-
Description
-
The genera Darwiniothamnus Harling, Lecocarpus Decaisne, and Macraea Hook. f. are endemic to the Galapagos Islands. Although wood anatomy of Lecocarpus has been considered by Carlquist (1958) and Eliasson (1971), the material available hitherto has been twigs rather than mature wood. The other two genera have not been studied with respect to wood anatomy.

Wood Anatomy of Hydrophyllaceae. I. Eriodictyon
-
Description
-
Hydrophyllaceae is a characteristically herbaceous family; only Eriodictyon Benth., Wigandia H.B.K., and the monotypic Turricula Macbr. can be considered woody (stems attaining a diameter of more than 1 em). Are plants such as these relicts from a woody ancestry, or is the family secondarily woody?
