TOPULAR SCIENCE REVIEW. 
Fig. 36. Anther-tube and recurved stigmas, characteristic of the tribe Cicho- 
racece of Composites. 
„ 37. Cleistogamous flower-hud of Lamium amplexicaule. 
„ 38. Vertical section of the same, showing the stigmas lying between the 
anthers. 
„ 39. The pistil removed to show how the style has become bent under 
constriction of the corolla. 
„ 40. Corolla of Salvia clandestina. The essential organs are quite in- 
visible. 
,, 41. Stamens of the same. The anthers stand edgeways, so that the 
lines of dehiscence face each other. 
„ 42. The styles removed. In one, the very long stigmas are unrolled 
artificially. 
„ 43. Stamens and stigmas of Prunella vulgaris. The posterior branch is 
being pollinated. 
,, 44. Two stamens and pistil of Rhinanthus Crista-gcdli var. major , adapted 
for intercrossing by the stigma being protruded. 
„ 45. Two stamens and pistil of same, var. minor , adapted for self-fertilisa- 
tion by the stigma being reflexed. 
„ 46. Stamens and pistil of the garden variety of Calceolaria. 
„ 47. Homomorphic form of Primrose, which produced plenty of good seed. 
„ 48. Flower of Glaux maritima, with the stigma recurved to secure self- 
fertilisation. 
„ 49. Side view, and 
„ 50. Front view of the pistil of Pinguicula lusitanica. 
„ 51. Pistil and the two stamens of same. The stigma is inserted into the 
anther-cells. 
„ 52. Two stamens and one carpel of Alisma Plantago. One stamen is 
spreading as for intercrossing ; the other is reflexed, a subsequent 
condition, for self-fertilisation. 
„ 53. Ophrys apifera, showing the pollinia falling from the anther-cells in 
the position for striking against the stigmatic surface. 
„ 54. Pollinium removed, showing the bend in the caulicle. 
„ 55. Stigma and pollinium of Cephalanthera. 
„ 56. Self-fertilising flower-bud of Tradeseantia erecta. The withered 
corolla is partially removed, the calyx not being represented. 
The stigma is being pollinated by the one perfect anther. The 
rest are aborted. 
57. Stamens and pistil of Hordeum murinum as they occur in the per- 
manently closed florets.
