creeping underground stem, flowers like dhose of Nicotiana afflnis, and 

 oval leaves. It gi'ows well in narrow border by Orchid House, but 

 cannot live in the open. 



Lobelia laxi flora, Mexico and Central America. — In a border against 

 corridor between two houses this is perfectly at home. It is not unlike 

 Siphocampylos hicolor. 



L. Tupa (L. Feuillei) Chile. — A fine plant, with red flowers, not 

 more than half-hardy. Against the wall of the stove it does well. 



Nieremhergia rivularis, La Plata. — Is said to be hardy, but in 

 Cambridge it succeeds only in a border close to plant-houses. 



Oxalis fiorihunda, Brazil. — Having woody stems above ground, 

 this cannot be classed with the species to be mentioned in next section. 

 • It is usually grown as a gTeenhouse plant. Here against the wall of 

 the Tropical Fern House it has flourished for a number of years, and 

 is very floriferous and showy. The white variety is also charming. 



Pelargonium Endlicherianum, Taurus. — This pretty species is 

 nearly hardy ; against the wall of Tropical Fern House it flourished for 

 some years. — P. triste, South Africa, is a very curious species, with 

 decompound leaves and blackish-yellow flowers, proceeding annually 

 from a woody rootstock. It has lived for many years against wall 

 of Tropical Fern House. 



Priva laevis, South America. — A low-growing Verbenaceous plant, 

 with lilac, very sweetly scented flowers. Nearly, if not quite, hardy. 



Rehmannia angulata [Bot. Mag. t. 8177), China. — Has lived 

 through 17° of frost in border by Palm House, flowering beautifully in 

 June. A very fine plant for outdoor cultivation where it can live. — 

 E. glutinosa, China, is not so ornamental as the last, but is hardier. 

 It has lived for many years in the border of the stove. 



Bulbous and tuberous plants receiving similar treatment at Cam- 

 bridge are: 



Agapanthus intermedins, A. Moorei, A, umhellaius, all from South 

 Africa, have sufficient hardiness to do quite well in borders between 

 the plant-houses. 



Amxiryllis Belladonna, Cape Colony. — The only true Amaryllis, and 

 one of the most beautiful of bulbs. It makes a great show along the 

 foot of the south wall of the Orchid House. There are several forms, 

 and variations in colour may be obtained from nearly white to deep 

 rosy -red. It is often a feature in the gardens of Devon and Cornwall, 

 and can be grown well at least as far north as Cambridge (fig. 69). 



Anoiganthus hrevifiorus, Natal. — Of the same family, this is very 

 different from the last, but grows with it under precisely the same 

 conditions. It has yellow flowers. 



Antholyza paniculata, South Africa. — Nearly, if not quite, hardy. 

 Useful as growing readily and not requiring much protection. 



Bowiea voluhilis, South Africa. — One of the most curious of bulbs. 

 The leaves may not be developed for years. Their place is taken by 

 abortive peduncles which recall those of Muscari comosum^mon-
