HOUSTONIA. [Cinchonaceae.] Pretty little tufted per- 

 ennial herbs, associating with alpines. Soil, a sandy mixture 

 of tbree parts peat to one of loam. Increased by division. 



HOVEA. [Leguminos£e, § Papilionaceae.] Beautiful green- 

 house evergreen shrubs. The flowers are of the shape of 

 those of the garden pea, which form is called butterfly-shaped ; 

 and hence papilionaceous, from papilio, a name given to 

 butterflies. Hoveas require a light fresh soil, but not rich : 

 three-fourths of fibry peat to one-fourth of light loam, adding 

 an eighth part of sand and as much of small charcoal, will 

 suit them. The drainage must be good : one-third of tlie 

 depth of the pots should be filled with crocks. They should 

 be watered with great caution, so as to avoid either wetness 

 or drought, and with clean rain water if possible. The best 

 plants are raised from seed, which is often perfected ; but 

 cuttings, which should be the tips of unblooming shoots two 

 inches long, will strike in sand. The cuttings are prepared 

 by cutting off the leaves from the lower half without bruising 

 the bark, and cutting the lower end clean through close 

 under where a leaf had grown ; they must be planted in pots 

 prepared b}^ being filled one-third with broken crocks, on this 

 half an inch of rough turfy lumps of soil, then to within an 

 inch of the top with sandy peat, pressed down very firm and 

 even ; the remainder is then to be filled up witli clean silver 

 sand, also pressed quite firm, and the whole must be watered 

 thoroughly with a fine-rosed pot. In an hour or two, when 

 it has drained, it will be fit for the cuttings. Insert them by 

 making a little hole with a smooth-pointed stick just to the 

 bottom of the sand ; put in the cutting so tha,t it rests on the 

 bottom, and press in the sand with the end of the stick to
