USPP5751P - Banisteriopsis caapi (cv) `Da Vine` - Google Patents

Abstract

A new and distinct Banisteriopsis caapi plant named 'Da Vine' which is particularly characterized by the rose color of its flower petals which fade with age to near white, and its medicinal properties.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a continuation application of application Ser. No. 266,114, filed on May 21, 1981 now abandoned.

BACKGROUND OF THE INVENTION

The invention relates to a new and distinct variety (cultivar) of the species Banisteriopsis caapi. The plant was discovered by and caused to be asexually reproduced from cuttings by applicant. All asexual reproductions of the plant show that the plant is stable, being true to the form to the discovered plant in all distinguishing respects.

The new plant is named `Da Vine`. This plant was discovered growing in a domestic garden in the Amazon rain-forest of South America. The instant plant presents flower petals which are rose colored fading to white with age. The instant plant may be distinguished from the species per se in flower color, B. caapi having pale pink flowers fading to pale yellow.

SUMMARY OF THE INVENTION

The instant plant may be particularly distinguished from typical forms of B. caapi by the following list of outstanding characteristics:

1. Leaves of different sizes, shapes, and texture. (see chart)

2. `Da Vine` has different size pedicels than are typical for B. cappi. (see chart)

3 The instant plant is more pubescent than is seen in the species. (see chart)

4. In flower petal color and size. (see chart)

5. `Da Vine` has no samaras. (nut)

The subject plant is being investigated for its medicinal value in cancer treatment and psycho-therapy. It is useful in treating post-encephalytic Parkinsonism and angina pectoris. It also has antiseptic, bactericidal properties and has both amoebicidal and antihelmentic action. It is an attractive house plant which seasonally blooms.

General observations: The plant appears to be seasonal in its flowering with flowering observed to occur from December through late March in Oahu, Hi. The plant parts are generally uniform in size throughout the plant; flower size and sizes of flowers parts are nearly identical as observed at Harold Lyon Arboretum, University of Hawaii, Oahu.
